Analgin is a widely used medication that has an affordable price. It belongs to the group of non-steroidal anti-inflammatory drugs. Its peculiarity is its pronounced analgesic and antipyretic properties.
The drug is produced in ampoules for intramuscular administration and in tablets. The second form is more popular. One tablet of the drug contains 250 or 500 mg of metamizole sodium. The active substance provides a strong analgesic, antipyretic and anti-inflammatory effect. It is quickly absorbed into the gastrointestinal tract and subsequently excreted by the kidneys.
Composition of the substance
The medicine is a strictly cylindrical tablet, designed with a chamfer and a score for convenient division into equal parts. Analgin tablets are usually dense white, sometimes with yellow splashes and a uniform yellowish tint.
The main active ingredient of the drug is metamizole sodium monohydrate. One tablet contains 500 mg. There are also tablets with a reduced dose of the active substance, equal to 250 mg.
In addition, the medicine contains a number of excipients, for example, potato starch, talc, calcium stearate and sodium lauryl sulfate.
The active components of the drug provide the drug with a pronounced analgesic, antipyretic and anti-inflammatory effect. Absorption of the components occurs in a short time through the gastrointestinal tract. After a certain period of time, it is excreted from the body by the kidneys without causing harm.
Analgin, solution
Dosage
The dosage depends on the intensity of pain, fever and individual sensitivity in response to taking analgin.
Low effective doses that control pain and fever should be chosen.
In children, to reduce fever, as a rule, a sufficient dose of metamizole is 10 mg per kilogram of body weight.
The onset of action ranges from 30 to 60 minutes after oral administration and 30 minutes after parenteral administration.
For children and adolescents under 14 years of age, a single dose of metamizole is 8-16 mg per kilogram of body weight. Adults and adolescents over 15 years of age (>53 kg) can take up to 1000 mg per dose. In case of insufficient effect of a single dose, depending on the maximum daily dose, the maximum single dose can be taken up to 4 times a day. The table below contains the recommended dosage and maximum doses.
The dosage for parenteral administration is usually from 6 mg to 16 mg of metamizole sodium per kilogram of body weight.
For patients aged 3 months to 1 year, analgin is administered only intramuscularly. The use of doses of more than 1000 mg of metamizole sodium parenterally should be carefully weighed due to the possible development of hypotensive reactions.
| Age (body weight) | Single dose |
| 3-11 months (5-8 kg) | 0.1-0.2 ml of analgin (50-100 mg of metamizole sodium) only intramuscularly |
| 1-3 years (9-15 kg) | 0.2-0.5 ml analgin (100-250 mg metamizole sodium) |
| 4-6 years (16-23 kg) | 0.3-0.8 ml analgin (150-400 mg metamizole sodium) |
| 7-9 years (24-30 kg) | 0.4-1 ml analgin (200-500 mg metamizole sodium) |
| 10-12 years (31-45 kg) | 0.5-1 ml analgin (250-500 mg metamizole sodium) |
| 13-14 years (46-53 kg) | 0.8-1.8 ml analgin (400-900 mg metamizole sodium) |
| Adults and patients over 15 years of age (> 53 kg) | 1-2 ml* analgin (500-1000 mg metamizole sodium) |
* - if necessary, it is possible to increase the single dose to 5 ml (which corresponds to 2500 mg of metamizole sodium) and the daily dose to 10 ml (which corresponds to 5000 mg of metamizole sodium).
Elderly patients
In elderly patients, the dose should be reduced, since the elimination of metabolites may be slowed down when taking analgin.
With decreased renal function and impaired creatinine clearance
In this category of patients, the dose should be reduced, since the excretion of metabolic products may be slowed down when taking metamizole.
Impaired renal or hepatic function
High doses should be avoided if renal or hepatic function is reduced. Short-term use without dose reduction is possible. Long-term use is not possible.
Method of administration
The route of administration depends on the desired therapeutic effect and the patient's condition. In most cases, oral administration is sufficient to achieve a satisfactory effect. If it is necessary to obtain a quick effect, intravenous or intramuscular administration of the drug is possible. When choosing a route of administration, it is necessary to take into account the higher risk of developing anaphylactic or anaphylactoid reactions with parenteral administration.
Analgin solution is administered intravenously or intramuscularly (in infants (3-11 months) - only intramuscularly). The temperature of the injected solution should be close to body temperature.
Analgin injection solution can be mixed or diluted with 5% glucose solution, 0.9% saline solution or lactated Ringer's solution. Due to the limited stability of these solutions, they should be used immediately.
Due to potential incompatibility, it is not recommended to use analgin solution with other drugs in the same syringe or intravenous infusion system.
Mode of application
The duration of treatment depends on the type and severity of the disease. Long-term therapy with Analgin requires regular monitoring of blood parameters, including counting the leukocyte formula.
Indications and contraindications
The scope of application of Analgin, instructions for which are included in the pack, is very diverse. It is used for pain of various origins, including those associated with injuries and surgical interventions, as well as those caused by tumor processes.
The instructions for use of the drug say that Analgin reduces pain in chronic pain of various origins. It facilitates the course of the disease in cases where it is not yet possible to carry out other correct treatment.
The pronounced antipyretic function allows the drug to be used at high temperatures during infectious diseases. It is used when other antipyretic drugs have failed to cope with elevated temperatures.

Most often, Analgin is used for headaches or toothaches, but its use is much wider than indicated in the instructions for the drug. In combination with antispasmodics, Analgin has shown high effectiveness in the fight against renal or biliary colic.
Analgin is strictly contraindicated for children.
There are not as many prohibitions on the use of the drug as there are for other similar drugs. However, you should be careful and not take the drug uncontrollably. It is important to take into account the patient’s condition and consult with a doctor to choose the right treatment regimen.
What does analgin help with?
The question of what analgin helps with is very common. The range of applications of this medicinal pain reliever is extremely wide. It can be used to relieve pain of various etiologies, in particular:
- After injury or surgery.
- Caused by spasms of the muscles of internal organs.
- Caused by the development of tumor processes.
As the instructions for Analgin indicate, it is indicated to alleviate the condition of patients with chronic pain of varying intensity. It allows you to stabilize the body’s condition when it is impossible to carry out other effective therapeutic measures. Analgin is used, the instructions for use indicate this, in order to lower high temperatures in infectious diseases, if this has not been achieved with other antipyretic drugs.
It is quite difficult to list exactly what analgin helps with due to the wide range of uses of the medicine. The most commonly taken tablets are for headaches and toothaches. It has proven its effectiveness in neuralgia and myalgia. In combination with antispasmodic drugs, analgin alleviates the patient's condition with renal and biliary colic.
Instructions for use
Independent and uncontrolled treatment with the drug is not allowed. Consultation with a doctor before using the tablets is required. This can be done at the MedArt clinic by making an appointment at a convenient time.
It is recommended to swallow each tablet whole without chewing it first. Be sure to drink plenty of water.
For acute pain, it is recommended to take a tablet with a dosage of 500 mg. If the intensity is pronounced, you can take two tablets at once, but keep in mind that no more than 3-4 tablets can be used per day. In this case, the course should not exceed five days from the start of treatment.
Analgin, the use of which is caused by spasms or fever, requires determining the exact dosage. As an antipyretic, tablets are taken in the smallest amount that is safe for the body, and also gives a reaction to high temperature. The course of treatment is no more than three days.
For children over 8 years old to 14 years old and weighing from 32 to 53 kg, a single dosage of the substance is 500 mg of the active component of the drug, that is, take one Analgin tablet. You can take up to four tablets per day, which is a multiple of 2000 mg of the substance.
Adult patients and adolescents over 15 years of age and weighing more than 53 kg can take 1-2 tablets at a time, which is a multiple of 1000 mg of the active ingredient. You are allowed to take no more than eight tablets per day, which is equal to 4000 mg of the active ingredient.
There are special conditions for elderly patients, as well as people suffering from kidney or liver failure. In this case, the minimum effective dosage of the drug is taken. High doses should be avoided, or the course of taking the drug should be significantly shortened.
Analgin, the dosage of which is determined by the nature of the disease, is effective and is often present in the medicine cabinet.
This is due to the difficulties of removing the breakdown products of the substance from the body. Since they are excreted by the kidneys, in such cases excretion will be slow or difficult, so the dosage is reduced to the minimum effective. During a long course of treatment, the doctor prescribes constant monitoring of the patient’s condition with regular leukocyte counts and blood monitoring.
Dosage
Only if it is impossible to take pills for any reason, intramuscular or intravenous injections are indicated. A single dose is 1-2 ml of a 50% solution of metamizole sodium. The daily dose should not exceed 4 ml.
To relieve pain, it is recommended to take a 500 mg tablet. For acute pain, the dose can be increased one-time to 2 tablets. You can take no more than 4 tablets per day, divided into 2-3 doses. The duration of therapy should not exceed 5 days. Analgin is taken as an antipyretic for no more than 3 days.
If you follow the dosage recommendations, problems with concentration and reaction speed are completely eliminated. Therefore, when using analgin to relieve pain, there are no restrictions on driving a car. Dangers arise only when large doses are used.
When using the drug, it should be taken into account that the toxic effects can be enhanced by other non-narcotic analgesics. It is also undesirable to use analgin simultaneously with tricyclic antidepressants and contraceptives. Barbiturates and phenylbutazone reduce the effectiveness of the drug, and sedatives and tranquilizers enhance it. The consumption of alcoholic beverages during pain relief with analgin is strictly prohibited.
Side effects
It is forbidden to use the drug for severe pain in the stomach, the origin of which has not been identified. Until a proper diagnosis is made, Analgin is not used in therapy. If the dosage and duration of the course of taking the tablets are not observed by the doctor, as well as when taking the drug under existing contraindications, allergic reactions may occur.
Most often, side effects are manifested by a skin rash, quite intense, as well as Quincke's edema. Less commonly observed are Lyell's and Stevens-Johnson syndromes, as well as anaphylactic shock. With long-term use of the drug as an anesthetic, changes occur in the blood formula.
Instructions for use of analgin highlight several side effects:
- risk of developing thrombocytopenia or leukopenia;
- bronchospasm attack;
- a strong decrease in blood pressure;
- malfunctions of the renal system.
When the first signs of deterioration in the patient’s condition appear, it is important to immediately stop taking the drug and report the incident to the treating doctor. To change painkillers, you need to visit a doctor to clarify the need to change the medication.
An overdose of a substance occurs in case of prolonged use of the drug, more than a week in a course in increased dosages, as a pain reliever. This may be manifested by nausea and vomiting, delirium, impaired consciousness, shortness of breath, and a sharp decrease in blood pressure.
If dangerous conditions of the body are determined, you should immediately consult a doctor and stop taking the drug. It is important to perform gastric lavage and also start using saline laxatives. They also increase their drinking regime and follow a diet. In particularly difficult cases, you will have to go to the hospital and undergo a hemodialysis procedure.
Contraindications and adverse reactions
The main contraindication for taking the drug is hypersensitivity to the active component in its composition. Treatment with the drug in the 1st trimester of pregnancy is strictly prohibited. If possible, you should refrain from taking it during other periods of pregnancy and during breastfeeding until the child reaches 3 months of age. The drug is not prescribed to children under 10 years of age, and before reaching adulthood, when using the medicine, you should first consult a doctor.
Treatment with analgin should be discontinued if hematopoiesis is suppressed. In particular, agranulocytosis, which is characterized by changes in peripheral blood, is a contraindication. This is accompanied by severe symptoms: weakness, bleeding, problems with the digestive system, etc.
It is strictly forbidden to use analgin to relieve acute pain in the abdominal area until the causes of their occurrence are determined. It is also not recommended to use the drug for the following pathologies:
- Kidney or liver failure.
- Anemia.
- Leukopenia.
- Bronchial asthma.
- Pyelonephritis and glomerulonephritis
Failure to comply with contraindications and overdose may result in dangerous allergic reactions. This often manifests itself as a rash on the skin and Quincke's edema. In rare cases, anaphylactic shock, Lyell's syndrome or Stevens-Johnson syndrome develops.
You cannot take analgin for a long time for pain relief. Otherwise, you can provoke blood count violations. The risks of developing leukopenia or thrombocytopenia increase significantly.
Other possible adverse reactions of the body:
- An attack of bronchospasm.
- Reduced blood pressure.
- Malfunction of the kidneys.
If any negative side reactions occur, you should stop taking the drug. It is advisable to inform your doctor about this and consult about a possible replacement of the pain medication.
An overdose is recorded when using the medicine for a week in large doses to relieve pain. In this case, nausea and severe vomiting, decreased blood pressure and shortness of breath, delirium and impaired consciousness, as well as many other dangerous disorders of the body, may occur. You should urgently rinse and take saline laxatives. An increased drinking regimen and intake of absorbents are indicated. In severe cases, hemodialysis will be necessary.
Pregnancy and lactation
Research on the effects on the body of pregnant women taking Analgin has not been carried out to a sufficient extent. As a result of animal studies, no serious disturbances in the functioning of the body were identified.
And yet, the drug can provoke serious perinatal problems, so taking the drug in the first and third trimester is strictly prohibited. The use of a substance in the second trimester occurs with extreme caution, under the supervision of a doctor, and only when the potential benefit to the mother is higher than the well-being of the fetus.
The drug is also not used during breastfeeding, as it easily passes into breast milk and can harm the baby. Feeding is allowed only 48 hours after completion of the drug.
The dosage of analgin for children is also prescribed by the doctor. Self-medication is not allowed in case of pathologies or fever in a child. Even half of a pill taken can have a detrimental effect on the body, so you should first undergo tests and get detailed advice from a qualified doctor. Only a doctor can prescribe medication in accordance with the nature of the disease.
Interaction with other drugs
In the case of simultaneous use of Analgin with cyclosporine, the level of the latter in the blood can be significantly reduced. It is important to inform your doctor about this; you may need to increase the dosage of the drug if you need to take a painkiller.
Severe hyporemia can occur when the substance is combined with chlorpromazine. Elderly patients are at high risk of developing hematological toxicity when used concomitantly with methotrexate.
Analgin should be used with acetylsalicylic acid and bupropion with great caution. The drug interacts and reduces the effectiveness of antihypertensive substances.
Analgin, 500 mg, tablets, 10 pcs.
When treating patients receiving cytotoxic drugs, metamizole sodium should only be taken under medical supervision.
Anaphylactic/anaphylactoid reactions
When choosing a method of drug administration, it should be taken into account that parenteral use is associated with a higher risk of anaphylactic/anaphylactoid reactions.
The following conditions cause an increased risk of developing hypersensitivity reactions to metamizole sodium:
- bronchial asthma induced by taking analgesics;
- intolerance to analgesics such as urticaria or angioedema;
- complete or incomplete combination of bronchial asthma, recurrent polyposis of the nose and paranasal sinuses and intolerance to acetylsalicylic acid or other non-steroidal anti-inflammatory drugs (including a history);
- chronic urticaria;
- alcohol intolerance (increased sensitivity to alcohol), against the background of which, even when taking a small amount of certain alcoholic beverages, patients experience sneezing, lacrimation and severe redness of the face. Alcohol intolerance may indicate a previously unidentified syndrome of bronchial asthma associated with analgesics (aspirin asthma);
- intolerance or hypersensitivity to dyes (for example, tartrazine) or preservatives (for example, benzoates);
- a history of anaphylactic or other immunological reactions to other pyrazolones, pyrazolidins and other non-narcotic analgesics (see section “Contraindications”).
Before using the drug Analgin, it is necessary to conduct a thorough interview with the patient. If it is determined that the patient is at particular risk of developing anaphylactoid reactions, the drug should be prescribed only after carefully weighing the risks and expected benefits. If a decision is made to use the drug Analgin in such patients, strict medical monitoring of their condition will be required and it is necessary to have the means to provide them with emergency care in the event of the development of anaphylactic/anaphylactoid reactions.
In predisposed patients, anaphylactic shock may occur; therefore, patients with bronchial asthma or atopy should be prescribed metamizole sodium with caution.
Severe skin reactions
Life-threatening skin reactions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been described with the use of metamizole sodium. If symptoms of SJS or TEN (such as a progressive skin rash often with blistering or mucosal lesions) appear, treatment with metamizole sodium should be discontinued immediately. It is prohibited to ever repeat treatment with the drug.
Patients should be informed about the subjective and objective symptoms of these diseases. They should be carefully monitored for skin reactions, especially during the first weeks of treatment.
Agranulocytosis
Agranulocytosis developing during treatment with metamizole is of immunoallergic origin and lasts for at least one week. Such a reaction occurs very rarely and can be severely life-threatening and even fatal. This reaction is not dose-related and may occur at any time during treatment.
All patients should be instructed to discontinue use of the drug and immediately consult their physician if the following subjective or objective symptoms possibly associated with neutropenia occur: fever, chills, sore throat, oral ulcers. In case of development of neutropenia (number of neutrophils <1500 per mm3), it is necessary to immediately stop treatment, urgently perform a comprehensive general blood test and continue monitoring the blood composition until the number of formed elements returns to normal values.
Pancytopenia
If pancytopenia develops, treatment should be stopped immediately; complete blood count parameters should be monitored until they return to normal.
All patients should be instructed to immediately seek medical attention if, during treatment with metamizole, subjective or objective symptoms suggestive of pathological changes in the blood appear (for example, general malaise, infection, persistent fever, bruising, bleeding, pallor).
Isolated hypotensive reactions
Administration of metamizole sodium may cause isolated hypotensive reactions. These reactions may depend on the dose of the drug and occur more often after parenteral administration.
Acute abdominal pain
It is unacceptable to use the drug Analgin to relieve acute abdominal pain (until the cause is determined).
Liver and kidney dysfunction
In patients with impaired liver or kidney function, Analgin should be used only after consulting a doctor, since in these patients the rate of elimination of the drug is reduced.
Impact on laboratory results
In patients treated with metamizole, changes in the results of laboratory tests performed using the Trinder reaction and similar reactions (for example, analysis of the concentration of creatinine, triglycerides, HDL cholesterol and serum uric acid) were recorded
Precautionary measures
Particular care should be taken when treating patients who receive cytostatic drugs, as well as people with atopic bronchial asthma and hay fever.
If symptoms of sore throat, stomatitis, chills, difficulty swallowing or fever are detected, you must immediately stop taking the drug and consult a specialist.
For acute abdominal pain, Analgin should not be used until the exact diagnosis is determined. Also, with long-term use of the drug, it is necessary to monitor and check the flow of peripheral blood by counting leukocytes.

Reviews
You can find a huge number of positive reviews online, as this is a time-tested medicine. The use of analgin is due to the low price of packaging the substance, as well as the popularity of the drug, because our mothers and fathers used it when such a variety of drugs was not on the market.
An excellent product, inexpensive and effective. I only get relief from headaches with Analgin. I always have it in my first aid kit and recommend it to my family. It’s very nice that regardless of price increases, a box of tablets can be purchased for just a ruble.
Anna, 45 years old
In a big city, headaches and muscle pain are constant companions. I always save myself with Analgin when I can’t stand the spasms. I carry it with me and always have a supply in the car. The low price of the drug is considered a huge advantage.

I have been using Analgin for many years and don’t even look towards newfangled expensive products. He saves 100%. An excellent product that the whole family uses.
Valeria, 62 years old
There are practically no negative reviews of Analgin. Users consider the only disadvantage to be inconvenience in swallowing and poor dissolution of the tablets. In this case, it is recommended to simply drink it with plenty of liquid so that it gets into the gastrointestinal tract more quickly.
