Acetylsalicylic acid is a very popular medicine, but this does not mean that everyone knows how and when to take it. I hope we have given you a comprehensive answer in this article.

Aspirin is a “folk” medicine with many uses: it lowers the temperature, thins the blood, and moderates headaches (toothaches). Also, this wonderful pill has been taken since the 70s of the last century to prevent heart attacks, strokes and oncology. And housewives have long been able to use it even for preservation. Inexpensive and familiar medicine, time-tested: date of invention - 1838.

Acetylsalicylic acid is still a widely used medicine. It is a pain reliever and anti-inflammatory drug used to treat:

• migraine;
• fever;
• neuralgia;
• rheumatism.

Cases of childhood illnesses after taking aspirin during the flu put the antipyretic functions of this drug in second place.

The beneficial properties of aspirin include the antithrombotic and cardioprotective properties of acetyl salicylic acid.

Prevention of thrombosis and cardiovascular diseases

By suppressing platelet aggregation (through inhibition of the production of thromboxane A2) and the synthesis of prostaglandins, acetylsalicylic acid prevents the development of thrombosis and cardiovascular pathologies.

Today, aspirin is often used as a prophylaxis against thrombosis and associated dangers to the heart and blood vessels.

For the discovery in 1971 and evidence of the thinning and cardioprotective properties of acetylsalicylic acid, John Vane, an English pharmacologist, received the Nobel Prize in 1982.

Prophylactic administration of small doses of acetylsalicylic acid reduces the risk of thrombosis in the coronary and cerebral arteries, which prevents heart attack, ischemic stroke and other cardiovascular diseases.

Chewing an aspirin tablet during a myocardial infarction gives the patient a chance to survive and is used in first aid.

Controversies: swine flu, thrombosis and aspirin

A few words about the new season swine flu, in which the medical standard protocol does not recommend taking aspirin.

In 2016, it leads, by the way, not only to pneumonia, but also to thrombosis.

Leonid Zhabotinsky died from a complication of swine flu - thrombosis of the intestinal arteries. Maybe acetylsalicylic acid, on the contrary, would have saved the weightlifter?

If aspirin is contraindicated, other drugs should be used for thrombosis:

• Warfarin, phenylin, etc.

When choosing a medicine, you need to carefully study its composition, since a number of modern thinning drugs are based on the same acetylsalicylic acid: for example, cardiomagnyl, aspecard, cardopyrin.

Prevention of cancer with aspirin

Oxford University Professor Peter Rothwell, having examined large group patients, found that constant intake of acetylsalicylic acid leads to a decrease in the incidence of:

• cancer of the pharynx and esophagus;
• bowel cancer;
• lung cancer;
• colon and rectal cancer.

Aspirin was taken for 5 years in small doses: 75 - 100 mg.

Later, the experiment was repeated on specific tumors and the actual effect of aspirin on gastrointestinal tumors was determined - the likelihood of cancer decreased by 20%. A reduction in the likelihood of cancer of other organs (breast, lung, etc.) when taking aspirin has not been proven.

The short duration of the effect was also established: as soon as the drug was stopped, the risk of developing cancer resumed.

Long-term prophylaxis with acetylsalicylic acid, even in small doses, can lead to intestinal gastroduodenopathy, duodenal and gastric ulcers, as well as gastrointestinal bleeding. Therefore, it is necessary to periodically take protectors for the gastrointestinal tract and monitor the level of platelets in the blood.

When is aspirin prohibited?

What is a benefit - the thinning properties of aspirin, becomes deadly in the presence of:

• stomach or intestinal ulcers;
• internal bleeding;
• hemophilia;
• thrombopenia;
• impaired vascular permeability;
• allergies to aspirin.

All these pathologies are contraindications for taking the drug.

• Acetylsalicylic acid is strictly prohibited when uterine bleeding, heavy periods, disintegrating tumors.
• Taking aspirin for bleeding disorders and inelastic blood vessels can cause extensive hemorrhages, including in the brain.
• An allergic reaction to salicylates often manifests itself in the form of bronchial asthma, and one tablet is enough to develop an allergy

Myths and misconceptions

One of the misconceptions common among the population: aspirin irritates the mucous membranes due to the acetylsalicylic acid it contains.

In fact, acetylsalicylic acid has nothing to do with side effects medications on the gastrointestinal tract - this effect is characteristic of absolutely all drugs from the NSAID series, which include aspirin.

The method of any NSAID is to block cyclooxygenase (an enzyme involved in the production of prostaglandins, which cause inflammatory processes).

There are two types of enzyme - COX-1 and COX-2.

In addition to the synthesis of prostaglandins, COX-1 also has benefits - it protects the mucous membranes of the gastrointestinal tract, ensuring the proliferation (division) of epithelial cells.

Most drugs (and aspirin among them), except for selective ones that act selectively, block both types of enzyme, which leads not only to stopping inflammatory process, but also to the depletion of the protective mucous layer of the gastrointestinal tract and the subsequent development of erosion phenomena.

Selective drugs (movalis, nimesulide, celecoxib) inhibit only COX-2. They are less harmful to the gastrointestinal tract, but also have side effects. Such NSAIDs are intended for long-term use and are used mainly for diseases of the joints and spine.

Second myth: A coated aspirin tablet with additives is less dangerous for the stomach and intestines than a regular one.

This bluff was intensively spread by pharmacologists, producing all sorts of variants of expensive “mild” aspirin - in a shell mixed with other elements, in particular, magnesium hydroxide:

• aspirin cardio,
• cardiomagnyl,
• aspecard etc.

In reality, despite the protective coating of the tablets, the harm from them to the stomach and intestines is exactly the same as from a regular aspirin tablet: the side effect does not occur from direct contact of the drug with the surfaces of the gastrointestinal tract, but from its absorption into the blood. Therefore, regardless of the form in which NSAIDs are taken (intramuscularly, intravenously, orally or as a topical gel), only the absorption rate will be different—the side effects will remain the same.

Conclusion: everything is relative

• it is dangerous for influenza;
• it irritates the gastrointestinal mucous membranes;
• it causes bleeding...

As a result, the drug is unwittingly considered almost the most dangerous of all NSAIDs.

In fact, as you have seen, this medicine has a lot of useful properties, but the contraindications are relative:

• The danger of influenza occurs in the form of a rare Reye's syndrome in children.
• The risk of inflammation and ulceration of the mucous membranes is no greater than when taking other NSAIDs.
• The properties of the blood thinner, being contraindications for coagulation disorders and bleeding, become therapeutic indications for thrombosis and cardiovascular disorders.

Absolutely any medical drug has contraindications, and they should always be carefully studied, and not take the medicine indiscriminately, guided by the principle: the more pills I take, the healthier I will be.

Acetylsalicylic acid, the formula of which is as follows: C9H8O4, has been successfully used by doctors for more than a hundred years.

A well-known drug that has anti-inflammatory, analgesic, antipyretic and antiplatelet effects. It is widely used for various febrile conditions characterized by increased body temperature

Therapeutic effect

After taking acetylsalicylic acid into the body, hyperemia decreases, capillary permeability at the site of inflammation decreases - all this leads to a noticeable analgesic and anti-inflammatory effect. The drug quickly penetrates into all tissues and fluids, absorption occurs in the intestines and liver.

• provides a lasting anti-inflammatory effect 24–48 hours after starting the medication;
• eliminates weak pain and medium degree intensity;
• reduces elevated temperature body, but does not affect normal indicators;
• acetylsalicylic acid thins the blood, disrupts platelet aggregation - the load on the heart muscle is reduced, and the risk of a heart attack is reduced.

The drug can be taken to prevent thrombosis, strokes, and reduce the risk of developing circulatory disorders in the brain.

Note! The antiaggregation effect of ASA is observed for 7 days after a single dose of the drug. Therefore, the product should not be taken before surgery or shortly before menstruation.

Regularly taken acetylsalicylic acid inhibits (inhibits) the formation of blood clots (thrombi), which can close the lumen of the artery. This reduces the risk of heart attack by almost half

• aspirin asthma;
• exacerbation of peptic ulcer, gastric and intestinal bleeding, gastritis;
• vitamin K deficiency, poor clotting blood, hemophilia;
• increased blood pressure in the portal vein system;
• renal and liver failure;
• dissecting aneurysm.

You should not drink acetylsalicylic acid if you are hypersensitive to salicylates, while taking Methotrexate, and should not be taken simultaneously with alcoholic beverages or ethanol-based medications.

Most of negative consequences while taking ASA it is associated with the digestive system - most often patients complain of pain in the epigastric region, nausea, vomiting, and diarrhea. During treatment, pain in the head may intensify, tinnitus may appear, and the functioning of the urinary system may deteriorate. If you are prone to allergies, a rash, bronchospasm, and Quincke's edema may appear. IN in rare cases erosions and ulcers develop in organs digestive tract, renal or liver failure. But if patients take the medicine, strictly following the instructions, then adverse reactions rarely appear.

You should not take acetylsalicylic acid together with other non-steroidal anti-inflammatory drugs, anticoagulants; Aspirin reduces the therapeutic effect of diuretics.

Note! With long-term use of ASA, temporary deterioration in hearing and vision often occurs. The consequences are reversible and go away on their own after discontinuation of the drug.

People suffering from stomach ulcers, asthmatics and those taking anticoagulants should be careful with its use. If you experience tinnitus, nausea, vomiting and dizziness after taking aspirin, there is certainly an overdose or an allergic reaction to the drug.

Can pregnant and lactating women and children take Aspirin?

Pediatric dosage: 250 mg twice daily, maximum allowed daily dose is 750 mg.

Acetylsalicylic acid is strictly prohibited during pregnancy in the first trimester - the drug has a teratogenic effect and can cause the child to develop congenital heart defects, splitting upper palate.

Note! ASA often causes miscarriage in the early stages.

You cannot take acetylsalicylic acid or paracetamol even in the third trimester - the drug causes pulmonary hypertension in the fetus, which causes the development of pathologies in the respiratory tract and impaired blood flow. Using ASA at this time can cause severe uterine bleeding.

During breastfeeding ASA cannot be taken, since the acid penetrates into the milk, which can lead to a deterioration in the baby’s health and the development of severe allergic reactions.

During the second trimester, admission is possible, but only if available acute indications and with the permission of the doctor, in the last period of gestation the baby is completely prohibited

Treatment of fever with acetylsalicylic acid

Acetylsalicylic acid (ASA) is an ester of acetic acid, Chemical substance, which has a lot of different effects on the body. This substance is an active component of many medications, the most popular of which are aspirin and citramon. These medicines are in medicine cabinets in every home, and this is not surprising, because it is difficult to overestimate the role of these drugs in modern medicine. Acetylsalicylic acid reduces even very high temperatures, and also improves the patient’s well-being by reducing pain.

However, the risks accompanying the use of this substance are also known. When is acetylsalicylic acid necessary, and when is it better to avoid it?

Action of acetylsalicylic acid

• help overcome fever;
• reduce headache and muscle pain;
• thin the blood;
• relieve inflammation.

Due to these effects, aspirin has been used for a very long time for colds, viral and bacterial infections, inflammatory diseases of various natures, accompanied by hyperthermia and pain.

Restrictions and contraindications

This drug gained immense popularity almost immediately after its introduction.

The main advantage of aspirin was that acetylsalicylic acid, which is part of it, lowers the temperature, and very quickly.

However, a little later, the physiological effects and mechanism of action of this substance were studied in more detail. It turned out that when taking these medications, some structures of liver and brain cells will be destroyed. These same structures suffer from the activity of viruses.

For this reason, it is not recommended to take acetylsalicylic acid to children for fever. This is especially true for ARVI. When taking aspirin, some children develop Reine's syndrome, a rare but deadly disease.

The syndrome is characterized by the destruction of liver cells and nervous tissue, and is accompanied by symptoms of acute liver failure. That is why ASA-based drugs are prohibited in most countries with developed medicine for use by children under 15 years of age.

For children would be better suited paracetamol. This antipyretic has far fewer side effects and the risk of overdose is lower.

As for adults, Reine's syndrome almost never occurs in them, but for people with liver problems it is better to limit the intake of aspirin and citramone.

In addition, it is known that ASA has a teratogenic effect, so its use is limited during pregnancy and lactation. In the first and third trimester of pregnancy, aspirin should be completely avoided, and in the second, you should consult a doctor.

In any case, you should be careful when taking such drugs during pregnancy and feeding. breast milk child.

Also, when taking ASA, it is worth considering its ability to thin the blood.

Thus, the following groups should refrain from using aspirin, citramone and other ASA-based drugs:

• pregnant women;
• nursing mothers;
• children under 15 years of age;
• patients with renal failure;
• people with problems with the blood clotting system.

Rules of use

For infectious and inflammatory diseases, acetylsalicylic acid is prescribed to adults for fever and headache in the form of aspirin. Aspirin is taken 0.5-1 tablet 3-4 times a day. You should not take more than 6 tablets per day, and the breaks between doses should be at least 4 hours. You should not take aspirin for more than 7 days without a doctor's prescription.

• dizziness;
• nausea;
• deterioration of hearing and vision;
• swelling of the throat;
• bronchospasm;
• in severe cases - stomach bleeding, loss of consciousness and coma.

During a cold, you should resort to ASA-based drugs in case of a strong rise in temperature. Acetylsalicylic acid for a cold without fever will do more harm than good. The result will be a double blow to the liver and brain (as mentioned, ASA and some viruses, including influenza, damage the same structures of hepatocytes and neurons).

However, aspirin does not directly affect the virus in any way. This drug is purely symptomatic, that is, it improves well-being, but does not destroy the cause of the disease.

Typically, ARVI is accompanied by a slight rise in body temperature - about 37-37.5 degrees Celsius. There is no need to knock it down, including with aspirin. By raising body temperature, the body fights infection. There is no need to be scared; you need to give your body time to cope with the pathogen.

The best treatment at this time is good rest and sleep, drinking plenty of fluids and clean Fresh air. Since ARVI is usually accompanied by inflammation of the upper respiratory tract, you need to worry about clearing them of phlegm. It is useful to gargle and rinse the nasopharynx with antiseptic solutions or simply saline solution. This thins the mucus and promotes its outflow.

Acetylsalicylic acid is needed if the temperature rises above 38 degrees during a cold.

This rise is usually observed with a bacterial complication. colds. In this case, the patient experiences severe headache and muscle pain, and sweats profusely.

Aspirin can help treat symptoms such as hyperthermia and pain, but it cannot eliminate pathogenic bacteria. Therefore, when high temperature It is necessary to take aspirin as an emergency drug, and immediately after that call a doctor.

He will examine the patient and determine the cause of the fever. If the disease is caused by bacterial inflammation, antibiotic therapy may be required. In some cases, hospitalization is recommended. This will ensure round-the-clock monitoring of the patient’s condition, and will also protect relatives from contracting a dangerous disease.

Please note that a temperature rise above 39 degrees is very dangerous, especially for children, so always monitor the child’s condition during illness.

Is it possible to give acetylsalicylic acid (aspirin) to children?

One of the very popular antipyretic drugs is the domestic drug Acetylsalicylic acid. Previously, it was often given to children with high fever or pain, but for several years doctors have been warning about the dangers of using this medication in children. At what age can a child be given Acetylsalicylic acid? Is this medicine allowed in pediatric practice or is it really dangerous in childhood?

Composition and release form

The main component in Acetylsalicylic acid is a substance with the same name. The German company Bayer also produces this medicine under the patented name Aspirin. Most forms of the drug are tablets. They can be regular, effervescent, or coated, which dissolves in the intestines. Acetylsalicylic acid is also found in powder from which an effervescent drink is prepared.

How does it work?

Acetylsalicylic acid belongs to medications called non-steroidal anti-inflammatory drugs. Like other representatives of this group of medications, it has analgesic and antipyretic, as well as anti-inflammatory effects.

The decrease in body temperature after taking acetisalicylic acid is due to the effect of this compound on the hypothalamus. The drug acts on the temperature regulation center located in this part of the brain, as a result of which the regulation point shifts (becomes lower). In addition, heat transfer is enhanced, and the processes of heat formation in the body under the influence of Acetylsalicylic acid are reduced. A person begins to actively sweat, his lung ventilation increases and the blood vessels of his skin dilate.

The anti-inflammatory effect of acetisalicylic acid is ensured by the binding of the drug to the enzyme “cyclooxygenase”, responsible for the production of inflammatory mediators called prostaglandins. As a result, the formation of these substances is inhibited, which is why the supply of energy to inflammatory processes stops.

A decrease in the concentration of a mediator in the blood called “bradykinin” is the basis for the analgesic effect of Acetylsalicylic acid. Due to this, taking the medicine reduces pain sensitivity. Also, the analgesic effect of the drug is due to its effect on prostaglandins, because they increase pain.

An equally important effect of Acetylsalicylic acid is its pronounced antiplatelet effect. The drug affects active substances called thromboxanes, due to which the drug thins the blood and reduces the risk of blood clots. This effect is especially in demand in adult patients (elderly).

Description interesting experiment conducted on the effect of aspirin on the human body, see the episode of the program “Live Healthy!”:

Can it be given to children?

Acetylsalicylic acid, as well as other drugs in which it is the main active ingredient or one of active compounds, are not recommended for the treatment of children under 15 years of age.

Once upon a time in pediatric practice, this medicine was prescribed to younger children, both at 2 years old and at 7 years old, but nowadays pediatricians prefer antipyretics that are safer for children, since Acetylsalicylic acid prescribed to a child can pose a serious danger.

Indications

Knowing the effect of Acetylsalicylic acid on the body, we can assume what this medicine helps with. He is appointed:

• For pain, such as toothache, muscle pain or headache.
• At high temperatures in adults.
• With a high risk of blood clots.
• For rheumatism, inflammation of the heart muscle or rheumatoid arthritis.
• For the prevention of cerebral vascular damage and myocardial infarction.

Dr. Komarovsky’s opinion on taking acetylsalicylic acid during a baby’s fever, see below:

Contraindications

Treatment with Acetylsalicylic acid is prohibited:

• In case of individual intolerance to such a medicine.
• For peptic ulcer disease, especially if it has worsened.
• For problems with blood clotting.
• For aspirin-induced asthma.
• During pregnancy in the first trimester and recent months gestation.
• When breastfeeding.
• For serious kidney diseases.
• For liver diseases.

Side effects

Like any other drugs, Acetylsalicylic acid can cause allergies, for example, urticaria, allergic rhinitis or anaphylactic shock. This medicine also has ulcerogenic activity, that is, it can provoke peptic ulcer disease or its exacerbation.

The use of Acetylsalicylic acid can also lead to:

• Disorders of the gastrointestinal tract. They often manifest themselves as nausea and heartburn. In some patients, the medicine causes vomiting or stomach bleeding.
• Problems with the urinary system. In rare cases, the drug causes kidney failure.
• Hematopoietic disorders. Long-term use of the drug leads to iron deficiency anemia, a decrease in the level of platelets and leukocytes.
• Bleeding. The risk of their occurrence increases with long-term treatment Acetylsalicylic acid. Most often, nosebleeds and bruises occur with the slightest damage to the skin.
• Disorders of the central nervous system. They arise due to high doses of the drug and are manifested by headaches, dizziness, and tinnitus.

Separately, it should be noted that the side effect of Acetylsalicylic acid in acute respiratory viral infections is the development of Reye's syndrome. This complication is often diagnosed in children under 15 years of age if they are given Aspirin for influenza, measles, chickenpox, or other viral infections. Its symptoms are liver damage and cerebral edema caused by disorders metabolic processes in these organs.

High risk of developing Reye's syndrome and possible complications after it they explain why Acetylsalicylic acid should not be given to children. This syndrome is dangerous due to the development of coma and a high percentage of deaths. Even if it is cured, the child may experience developmental delays and nerve damage.

Elena Malysheva’s program talks in detail about the causes and consequences of Reye’s syndrome in children:

Instructions for use

Tablets are taken only after meals, with either plain water, or some alkaline liquid, for example, mineral water rich in alkalis.

Dosage

Over the age of 15 years and in adult patients with high fever or moderate pain, give from 40 to 1000 mg of acetylsalicylic acid per dose. Often a single dose is 250 or 500 mg active substance, but a more precise dosage should be determined by a doctor.

The medicine is taken 2-6 times a day, pausing between doses for at least four hours. The maximum amount of Acetylsalicylic acid per day for a child over 15 years old should not be more than 3 g.

How long can I take it?

The duration of treatment with Acetylsalicylic acid, if the medicine is used to reduce fever, should not be more than three days. If the purpose of using the drug is an analgesic effect, use should not exceed seven days.

Overdose

If you drink Acetylsalicylic acid in a dose of more than 4 g per day, it can cause heavy defeat lungs and liver, as well as brain and kidneys. Poisoning with such a drug leads to heavy sweating, hearing loss, skin allergic reactions and others negative symptoms. For treatment, immediate gastric lavage and consultation with a doctor are indicated.

Terms of purchase and storage

You can buy Acetylsalicylic acid at any pharmacy. This is an affordable medicine, for the purchase of which you do not need to show a prescription. The medicine should be stored at home at room temperature and in a dry place, away from children. The shelf life of the tablets, depending on the manufacturer, is 3-5 years.

Reviews

The use of Acetylsalicylic acid in children has different opinions. There are mothers who do not see any particular danger in such a drug and give it to their child when they have a fever. However, many more parents and pediatricians refuse treatment with this drug in childhood, preferring other antipyretic drugs approved for children.

Acetylsalicylic acid is medicine with a pronounced anti-inflammatory, antipyretic, analgesic and antiplatelet (reduces the process of platelet aggregation) effect.

pharmachologic effect

The mechanism of action of acetylsalicylic acid is due to its ability to interfere with the synthesis of prostaglandins, which play a major role in the development of inflammatory processes, fever and pain.

A decrease in the number of prostaglandins in the thermoregulation center leads to vasodilation and increased sweating, which causes the antipyretic effect of the drug. In addition, the use of acetylsalicylic acid can reduce sensitivity nerve endings to pain mediators by reducing the influence of prostaglandins on them. When taken orally, the maximum concentration of acetylsalicylic acid in the blood can be observed within minutes, and the salicylate formed as a result of metabolism can be observed after 0.3-2 hours. Acetylsalicylic acid is excreted through the kidneys, the half-life is 20 minutes, the half-life for salicylate is 2 hours.

Indications for use of Acetylsalicylic acid

Acetylsalicylic acid, the indications for which are determined by its properties, is prescribed for:

• prevention of myocardial infarction with coronary disease heart or in the prevention of relapse;
• the presence of risk factors for silent myocardial ischemia, coronary heart disease, unstable angina;
• prevention of thromboembolism (blockage of a vessel with a blood clot), valvular mitral heart defects, prolapse (dysfunction) of the mitral valve, atrial fibrillation(loss of the ability of the muscle fibers of the atria to work synchronously);

Acetylsalicylic acid for fever in children and adults

Acetylsalicylic acid is the most popular drug in the treatment of many diseases. It is often used for fever by children and adults. However, many do not think about the fact that even such a popular medicine has side effects. Not every person can use it, as there are clear contraindications.

Acetylsalicylic acid is an acetic ester that is used in many drugs as active ingredient. A large concentration of it is contained in aspirin and citramone. These medications are well-known and are found in many people's medicine cabinets.

As soon as a headache begins, a runny nose or pain appears, people immediately start using acetylsalicylic acid. Its two main properties are the suppression of temperature and pain receptors. A person feels better after using the drug.

Why should you consider this medicine if it has such good effects? Because any medicine can cause harm to a person when used incorrectly. We’ll talk about this on the website ogrippe.com.

Action of acetylsalicylic acid

Before using any medicine, you should read the instructions and consult your doctor. Although acetylsalicylic acid is sold without a prescription, its effect can be negative. The doctor will be able to familiarize the patient with the effect of this drug, which will have a specific effect in a certain case.

Despite the popularity of this medicine, you should be aware. First, let's introduce all the properties that ASA has:

• Overcomes fever.
• Relieves inflammation.
• Reduces muscle and headache pain.
• Thins the blood.
• Reduces capillary permeability.
• Reduces vascular spasms and lowers blood pressure.

In some cases, this impact becomes negative. Let's take such a simple example as low temperature. Up to 38 degrees is considered to be a beneficial temperature, especially in case of illness. It is at such a high temperature that the body effectively fights the infection that caused the disease. If you knock it down, then you can reduce the activity of the immune system.

Due to its properties, acetylsalicylic acid is popular among many people. Almost every home has a drug with this component. It is used for any viral, inflammatory and infectious diseases which are accompanied by pain and high fever.

Contraindications and restrictions

Despite the usefulness of ASA, there are various contraindications and restrictions. People actively use this remedy because of its ability to quickly relieve fever. However, further research shows that long-term use The drug affects the structure of brain and liver cells. Some viral diseases have the same negative impact.

For this reason, experts prohibit the use of ASA by children under 15 years of age. Especially with ARVI, this medicine has a negative effect. When using the drug, children develop Reye's syndrome, a fatal rare disease. Its main symptom is defeat nervous system and liver, in which liver failure is noted. That is why developed countries have already abandoned this drug in the treatment of children.

If it is necessary to eliminate a headache or reduce a child's temperature, it is better to use Paracetamol. This drug has no side effects and no possibility of overdose.

Adults do not suffer from Reye's syndrome, but if liver disease is present, the medication should be discontinued. It is also contraindicated for pregnant and breastfeeding women to take ASA. In the 1st and 3rd trimester, this drug is prohibited, and in the 2nd trimester it should be taken only after consultation with a doctor.

Acetylsalicylic acid should be taken only as directed, given the fact that it thins the blood. Thus, aspirin is contraindicated in the following persons:

• Children under 15 years old.
• Pregnant women.
• Patients with liver failure.
• Nursing mothers.
• Patients with blood clotting problems.

Rules of use

Before taking the drug, you should read the instructions, which outline the rules of use. It is also recommended to take acetylsalicylic acid only after consulting a doctor. Overdoses are fraught with consequences.

For inflammatory or infectious diseases, the medicine is prescribed in the form of aspirin to adults for headaches and fever. The dosage is 0.5-1 tablet 3-4 times a day. The breaks between doses should be 4 hours, and you should not take more than 6 tablets per day. Taking the drug for more than 7 days is prohibited.

ASA is available in the form of tablets or effervescent drinks that are dipped into water. Take the medicine with plenty of liquid. It is better if it is milk or mineral water.

If the dosage is exceeded, one should not count on the absence of side effects, which may be in the form of:

1. Dizziness.
2. Bronchospasms.
3. Swelling of the throat.
4. Nausea.
5. Deterioration of vision or hearing.
6. Gastric bleeding, loss of consciousness and coma in severe cases.

As already mentioned, the drug is not prescribed to children under 15 years of age to avoid the development of Reye's syndrome. After 15 years, the dosage of this drug for children is 0.5 tablets (250 mg) 2 times a day. Maximum daily norm reaches 750 mg.

Before use, the tablet should be thoroughly crushed and washed down with plenty of liquid. The medicine is taken after meals. As an antipyretic medicine, it is used for no more than 3 days. It is used as a pain reliever for no more than a week.

Features of taking ASA for ARVI

ARVI is the most common disease that causes high fever. However, here too there are peculiarities of taking ASA. Preparations based on this acid are taken only at high temperatures (more than 38.5 degrees). If there is no fever, then acetylsalicylic acid is not used in treatment so as not to provoke a double effect on the liver and brain structure, since the influenza virus already affects them.

It should be remembered that ASA is a symptomatic medicine. It does not fight infection, but reduces fever and reduces pain. Therefore, intensive use of aspirin is not necessary.

ARVI is usually accompanied by a low-grade fever of up to 38 degrees. This temperature there is no need to knock it down, since it is it that helps the body fight viruses. If it begins to rise to high levels, then ASA can be used.

As long as the temperature does not exceed normal, other measures should be taken:

• Drink plenty.
• Have a full rest.
• Sleep.
• Freshen the air in the room.
• Rinse the nasopharynx and gargle with antiseptic medications and saline solutions.

Acetylsalicylic acid becomes necessary when the temperature rises above 38.5°C. In such a situation, the patient begins to sweat profusely and feels a severe headache.

An increase in temperature during ARVI indicates the attachment of bacteria to viruses. Taking aspirin in in this case will be an ambulance in relieving symptoms. However, the elimination of infections should be dealt with by a doctor, whom you need to contact or call to your home.

The doctor will determine the cause of the fever. If it is caused by bacteria, then antibacterial therapy will be prescribed. In some cases, hospitalization will be required. This measure will be carried out if the child’s temperature rises to more than 39°C.

Reception of ASA by children

IN old times The main antipyretic drug was ASA, which was used even in the treatment of children. However, taking this medication has side effects in the form of Reye's syndrome, which develops specifically in children under 15 years of age. In this case, toxic damage to the brain and the development of renal and hepatic failure occur.

Other side effects of taking ASA in children are:

If parents are interested in improving their child's condition, then instead of ASA they will give Paracetamol or Ibuprofen, which has fewer side effects and is approved for use by children.

Forecast

Acetylsalicylic acid is an effective antipyretic agent. She happens to be good remedy in a situation where it is urgently necessary to lower the temperature, which has a negative effect on the sick body. Only a single use of the drug gives a positive prognosis with no side effects.

ASA should only be used by persons over 15 years of age. Until this age, other drugs should be used, such as Ibuprofen or Paracetamol. Children should be treated by pediatricians who have a better understanding of the medications that will help them.

It should be remembered that aspirin relieves pain and fever, but does not fight viruses and bacteria. Using ASA alone as a treatment is useless and even disastrous. In this case, the disease can cause complications, which will affect the patient’s life expectancy.

Also, pregnant and lactating women should avoid taking acetylsalicylic acid, since the substances of the drug enter the body of the baby, who is included in the group of people for whom this drug is contraindicated.

Does Aspirin reduce fever?

Aspirin for fever is considered a popular antipyretic for infectious and inflammatory processes. The drug is based on the action of an acetylsalicylic derivative. It is recommended to start eliminating fever when the thermometer readings are more than 38.5 degrees, but if a person has severe symptoms of the disease and at the same time the temperature is difficult to tolerate, it is allowed to start using the drug at values ​​from 38 degrees.

Composition and pharmacological properties

The drug is a derivative of salicylic acid and is classified as an NSAID. Available in the form of tablets (100, 500 mg) and powder. It is preferable to use effervescent tablets or powder, since the effect from them comes faster.

The use of Aspirin can cause the following effects:

• Reducing pain in the head and muscles;
• Reducing fever and severity of inflammation;
• Blood thinning.

Considering the range of effects, the drug is prescribed mainly for acute respiratory viral infections and other infections that combine signs of inflammation and fever. Although today there are a large number of drugs with a wider arsenal of properties and fewer side effects (paracetamol, analgin), the use of Aspirin remains just as relevant. Basically, the choice falls on this drug, due to the fact that Aspirin brings down the temperature.

When is antipyretic action necessary?

The thermoregulatory center is located in the hypothalamic region of the human brain. At high levels of fever, in certain cases corresponding to febrile manifestations, Aspirin can be of great help. At values ​​less than 38 degrees, use is not recommended: the risk of side effects on the body is high.

Subfebrile temperature values ​​often correspond to the condition of ARVI mild degree severity in the form of a simple cold. And instead of reducing the temperature with antipyretics, it is better to carry out local measures in the form of rinsing and irrigating the nasal cavity and throat with saline and other antiseptics. A temperature of 37 degrees often indicates the body’s fight against the invading virus. The best thing that can be done is to provide rest and care, and increase fluid intake.

The drug Aspirin effectively reduces temperature in degrees. The main effects are noted on headaches and fever. However, if the pill is taken and the readings continue to rise, you should consult a doctor. Do not assume that with the help of Aspirin you can completely eliminate the inflammatory process in the body.

High temperatures can be caused by bacteria and viruses. Therefore, it is so necessary to contact a specialist. After the examination and examination, the doctor will prescribe the necessary medications (antibiotics, antiviral drugs and, if necessary, another remedy), normalizing the condition and eliminating the symptoms of fever.

Contraindications

Use is contraindicated for the following diseases and conditions:

• Ulcerative processes in the digestive tract;
• Pregnancy, lactation and menstruation;
• Disruption of the coagulation system, hemorrhagic diathesis;
• Bronchial asthma;
• Liver and kidney diseases;
• Childhood;
• Individual intolerance to the components of the drug.

The medicine must be used strictly in accordance with the instructions and for no more than 1 week. If the basic rules of use are not followed or the body reacts, various types of adverse reactions may occur. Often there are disturbances in the coagulation system, leading to exacerbation of ulcers and even gastric bleeding.

Side effects of the drug

In some cases, allergies may occur. Allergic reactions may include urticaria, Quincke's edema, and spasmodic cough. To reduce the likelihood of side effects of the drug, it is necessary to take the drug with plenty of liquid and only after meals.

Overdose may cause hearing problems, skin reactions(sweating, rashes), symptoms of suffocation (swelling of the throat, difficulty breathing), hyperglycemia and coma. All these conditions are very dangerous, therefore, when the first signs of drug resistance appear, you cannot take Aspirin for fever and you should immediately consult a doctor.

Dosage regimen

In pediatric practice, taking Aspirin for fever is not recommended until age 15. This is due to the fact that the child is at high risk of developing Reine's syndrome, which leads to encephalopathy and fatty liver degeneration. Therefore, before starting use, you should consult a specialist.

The following daily dosages for children are possible:

At a temperature of 38, an adult can take Aspirin in a single dose of 0.04 to 1 gram. Instructions for use allow a daily load of up to 8 grams. The frequency of administration is 2-6 times a day. But basically the recommended dose for adults is 1 tablet (100 mg) 3 times a day. You should drink plenty of water after eating.

Pharmacological properties of the drug

Acetylsalicylic acid, when ingested, disrupts the synthesis of prostaglandins, substances that play a major role in the development of febrile conditions, inflammatory processes and pain.

Suppression of prostaglandin production leads to dilation blood vessels, which helps to increase sweat secretion, which explains the antipyretic effect of the drug.

The use of drugs based on acetylsalicylic acid in therapy leads to a decrease in the sensitivity of nerve endings, which explains the pronounced analgesic effect of this drug. Acetylsalicylic acid is excreted from the body through the kidneys.

• Pain syndrome of various origins - severe headaches, toothache, muscle pain for influenza and viral infections, menstrual pain, migraines, joint pain;
• Diseases of the spinal column accompanied by severe pain – osteochondrosis, lumbago;
• Increased body temperature, fever caused by infectious and inflammatory processes in the body;
• Prevention of the development of myocardial infarction or ischemic stroke due to impaired circulatory function, thromboaggregation, and very thick blood;
• Unstable angina;
• Genetic predisposition to thromboembolism, thrombophlebitis;
• Heart defects, mitral valve prolapse (impaired functioning);
• Pulmonary infarction, pulmonary embolism.

Contraindications for use

Acetylsalicylic acid tablets have a number of contraindications for use. These include:

• Hemorrhagic diathesis and vasculitis;
• Gastritis of erosive or corrosive origin;
• Peptic ulcer of the stomach and duodenum;
• Poor blood clotting, tendency to bleed;

The duration of therapy with this drug is determined by the doctor depending on the indications, severity of the inflammatory process and individual characteristics body, but this period should not exceed more than one day.

IN for preventive purposes To reduce the risk of myocardial infarction and thromboaggregation, adults are prescribed ½ tablet of aspirin once a day. The duration of therapy is about 1-2 months. During this period, it is necessary to constantly monitor the clinical picture of the blood, monitor the rate of blood clotting and the number of platelets.

Side effects

Before starting to use acetylsalicylic acid tablets, the patient should consult a doctor. If the dose is exceeded or uncontrolled and long-term use of this drug, the following side effects may develop:

Tablets are used strictly specified dosage(minimally effective) and under strict medical supervision. During the treatment period to the expectant mother You need to regularly take blood tests to assess your hematocrit and platelet levels.

The use of acetylsalicylic acid in the 3rd trimester is prohibited due to the huge risk of early closure of the aortic duct in the fetus. In addition, the drug can lead to hemorrhages in the ventricles of the brain in the fetus and cause the risk of massive bleeding in the expectant mother.

The use of acetylsalicylic acid tablets during breastfeeding is prohibited due to high risk development of liver and kidney failure in a child. In addition, if acetylsalicylic acid enters the baby's body with mother's milk, it can lead to severe internal bleeding in the child. If it is necessary to use this drug during breastfeeding, the baby should be switched to artificial nutrition with an adapted milk formula.

Every day, millions of people open their home medicine cabinets in search of aspirin. It is taken for headaches, hangovers, and in many other cases. The medicine is so familiar that rarely does anyone look at the instructions to find out what acetylsalicylic acid helps with. But is this drug so safe, how can it help and harm the body?

One of the most famous medications is aspirin. Many people trust only him: it is inexpensive, tested over several generations. If your health worsens - you have a headache, a fever, or symptoms of ARVI appear, then aspirin becomes your salvation. Those who have had too much alcohol also resort to it. Even if you have a stomach ache, the same pill is used.

Over the years of “work” as an analgesic and antipyretic agent, acetylsalicylic acid has acquired a good reputation among patients. This drug is used all over the world and consistently demonstrates high efficiency. In addition, aspirin can prevent the formation of blood clots and is prescribed to older people to thin the blood and prevent strokes.

At the same time, doctors began to suspect that aspirin was not as harmless as it previously seemed. Studies have shown that this medicine often provokes internal bleeding. If taken regularly and uncontrolled, it can cause serious disturbances in the functioning of the gastrointestinal tract (including causing ulcers). There have been recorded cases of the development of other pathologies due to constant use of the drug. Thus, due to the ability of acetylsalicylic acid to increase vascular permeability, the composition of the blood may change, which negatively affects the clotting process.

There have been rumors that in some countries aspirin has become a banned drug. This is not true. It’s just not prescribed to children under 15 years of age, pregnant women, breastfeeding women, and those who suffer from diseases of the digestive system. Acetylsalicylic acid is useful only for those individuals who are at risk for cerebral hemorrhage. Healthy people can take 1-2 aspirin tablets, but this should only be done if absolutely necessary. To avoid unpleasant (and dangerous) side effects, it is better not to abuse it.

Every medicine, even one as well-known and accessible as aspirin, should be used as directed. The main indications for its use are the following diseases and conditions:

• fever;
• headache (including migraine);
• circulatory disorders (including blood supply to the brain);
• thrombosis;
• heart attack;
• rheumatism;
• pain of various origins.

During the cold season, acetylsalicylic acid can be especially useful. What does it help with? From the temperature that accompanies the infectious-inflammatory process. It is preferable to knock it down with water-soluble tablets or powders. The pop contains not only acetylsalicylic acid, but also vitamin C, which will help you fight a cold faster. If you only have a regular aspirin tablet on hand, you need to crush it. Effervescent aspirin is diluted in 50-70 ml of water at room temperature. The powder is poured into hot water.

Aspirin should not be taken on an empty stomach! You should take the tablet with a large portion of water or jelly, or even better, use milk for these purposes. The standard dosage is 0.25-1 g 3 to 4 times a day.

If the temperature lasts longer than 3 days, then you should stop taking acetylsalicylic acid and immediately call a doctor.

Today, more effective and safe drugs have been developed to combat fever - based on paracetamol or ibuprofen: Panadol, Paracetamol, Efferalgan. The likelihood of side effects when taking them is much lower than when using aspirin.

Many people have experience treating headaches with aspirin. The result is not always successful. So does acetylsalicylic acid help with headaches? If a person is suffering from ordinary pain (and not a migraine) and takes the pill at the first sign of discomfort, then yes, this drug will be effective.

If a headache strikes an adult healthy person at work, you can take a loading dose of acetylsalicylic acid - 2 tablets. If you have the opportunity to rest, then you shouldn’t risk it, it’s better to take 1 tablet.

Aspirin cannot be taken for a long time, so if the discomfort does not go away for several days, then you need to stop taking it and get examined, since headaches are a symptom of 40 diseases!

IN pharmacy assortment you can find more potent drugs of the same spectrum. They cost much more, but they also act quickly and much more delicately. These are Imet, Nurofen, Ibuprom.

Withdrawal (or hangover) syndrome is a painful condition that deprives a person of his ability to work and brings a lot of inconvenience. Many people know that aspirin is a good helper for someone who has drunk too much. Acetylsalicylic acid will provide relief from a hangover, but will only eliminate external manifestations poisoning (that is, headache, aching joints and muscles), but not the poison itself, will not help free the body from ethanol breakdown products. Drinking aspirin is allowed no earlier than 6 hours after drinking alcohol.

The best option for eliminating hangover syndrome is effervescent aspirin. It contains adsorbents that remove toxins. The tablet is diluted in large quantities water - this will reduce dehydration.

To others known drug, which will “heal” after drinking too much is Alka-Seltzer.

How to take aspirin to thin the blood?

A problem like thick blood, becomes relevant in old age. On the background hormonal imbalance platelet aggregation decreases, which leads to the appearance of blood clots. After 40 years (for women) and 45 years (for men), it is recommended to take blood thinning medications. And the first on their list is acetylsalicylic acid.

Aspirin is often prescribed to prevent thrombosis in adulthood. To do this, the drug should be taken for a long time (lifelong) in very small doses. The tablets are taken in the evening before bed with water. In an emergency, the tablet should be chewed or placed under the tongue. The daily dose of acetylsalicylic acid is 100 mg.

The drugs Cardiomagnyl, Warfarin, Aspercard have a similar effect.

Aspirin can not only be taken orally, but also used externally. In cosmetology, acetylsalicylic acid is often used for acne. To do this, apply a mask to the problem area. It’s easy to prepare: crush a few tablets, dilute with cool water, bring to a mushy consistency and apply to pimples for 5-7 minutes.

When does aspirin become poisonous?

Before you swallow another aspirin pill, it is advisable to make sure that you have no contraindications to taking it. First of all, this applies to women, since the drug cannot be taken during pregnancy and breastfeeding.

Medicines based on acetylsalicylic acid should not be taken if you have the following pathologies:

• ulcer;
• internal bleeding;
• kidney and liver diseases;
• nasal polyps in combination with asthmatic syndrome;
• thrombocytopenia;
• allergy to active ingredients.

For patients who suffer from gout, gastritis, anemia and cardiac dysfunction, it is better to obtain a doctor's permission before taking aspirin.

If the child is under 15 years old, then it is better not to conduct experiments and refuse treatment with aspirin, since WHO does not recommend this to avoid unforeseen complications. IN as a last resort, it is better to give preference to an effervescent drug: it has a more gentle effect on the digestive tract.

To minimize or completely eliminate side effects, you should not take the medicine for longer than 2-14 days, and the largest daily dose should not exceed 3 g (and it should be divided into 2-3 doses).

It is believed that 1-2 tablets of aspirin will not cause harm. In most cases this is true. But even short-term use of acetylsalicylic acid can cause the following undesirable reactions:

• nausea, heartburn, loss of appetite;
• vomiting, stomach pain;
• disturbances in liver function;
• dizziness;
• hearing loss;
• bleeding;
• skin rashes.

An overdose of the drug is extremely dangerous.
