Analogs

• Clemastine-Eskom;
• Clemastine;
• Rivtagil.

Instructions

The antihistamine is available in tablets, injection solutions, syrup. Pills are most commonly used internally.

The neutralization of allergy symptoms in adult patients and children who have turned 12 years old is carried out with the help of one tablet, prescribed 2 r. in a day. With the development of complicated symptoms (anaphylaxis), the dosage of the drug is increased to six tablets per day.

Children from one to 12 years old take 0.5 tablets no more than twice a day. The drug is recommended to be taken before meals. For better absorption, the tablet must be washed down with a minimum amount of water.

Before using the drug, you must check the expiration date.

It is important to remember that children under one year old are not allowed to give Tavegil.

In case of a complicated course of allergies, Clemastine can be administered to the patient intravenously. The dosage for intravenous infusion should be no more than 2 ml. The drug is administered very slowly, under the control of blood pressure.

Pediatric dosage for intravenous administration is calculated by the child's body weight: per 1 kg - 0.025 mg of the drug.

The dosage of the drug must be reduced when treating allergies in patients over 55 years of age. This is due to the possibility of developing negative symptoms (lowering blood pressure, drowsiness).

Important! Tavegil tablets, like all other antihistamines, must be taken for 7 days. Longer use of one drug leads to addiction, which reduces the effectiveness in treating allergies.

As a rule, if necessary, after the prescribed treatment course, Tavegil is changed to another similar drug.

Overdose

In the event that the patient neglects medical prescriptions, independently increasing or decreasing the dose of the drug, an overdose of the drug may occur. It is manifested by the following symptoms:

• spastic headache;
• dry mucous membranes;

• dizziness, short-term loss of consciousness;
• attacks of nausea, accompanied by vomiting;
• in addition, an overdose of Tavegil can provoke the development of depression of the nervous system, as a result of which the patient is in complete relaxation and euphoria;
• maybe, on the contrary, the central nervous system intensifies its activity. This is accompanied by an increase in nervous excitability and trembling of the limbs. In any of these cases, emergency assistance is required.

First of all, you need to try to find out how much of the drug caused the intoxication. The next step is to stop the intake of toxic substances in the body. Then the patient's stomach should be flushed, causing vomiting.

After that, it is necessary to give the patient Activated carbon, Enterosgel or any other sorbent to remove toxins from the body. Further therapeutic manipulations are carried out symptomatically.

Reviews

Despite the fact that this drug belongs to the first generation of antihistamines, many patients use it to treat allergies. They note that it eliminates all the symptoms of the disease, from skin rashes to allergic rhinitis.

Tavegil tablets are still in demand in the pharmacy chain, in addition, many doctors prescribe this drug to treat the disease. Clemastine quickly relieves negative manifestations and significantly alleviates the patient's condition.

Many are attracted by the low cost of the drug. The average price for Tavegil tablets is 120 rubles per pack (10 pcs.). It is quite inexpensive in comparison with similar antihistamines, which have a similar effect, but cost several times more.

Almost every medication has its own drawbacks. Tavegil is no exception. The disadvantages of the drug include the fact that it cannot be used by pregnant and lactating women. The final conclusions about the negative manifestation of Tavegil during this period of time have not been clinically proven, however, in order not to harm the fetus and the woman, it is better to avoid its use.

Some patients note the presence of side symptoms: tachycardia, drowsiness. It is especially difficult to tolerate injections in case of illness. Patients feel dizzy, they have a sharp drop in blood pressure. Therefore, the introduction of the solution should be carried out very slowly, only in a hospital or emergency room, with compliance with sterility and in the presence of a doctor to provide emergency care for the treatment or occurrence of anaphylactic reactions.

Parents note that the drug is poorly tolerated by children. They become restless, moody, and agitated. Therefore, parents prefer antihistamines of a later generation, which do not have such side effects.

In no case should you self-medicate! The dosage of the drug and the conditions for its administration are chosen by the attending physician, who first examines the patient's history and diagnoses the cause of the allergy.
