Tavegil tablets contain the active substance clemastine and are a type of sedative antihistamine. So characterizes the "Tavegil" instruction. It works by inhibiting the action of histamine produced by the body. It is stored in a bound state in cells called mast cells in almost all tissues. When the body responds to a foreign body (an allergen, such as flower pollen, pet hair, dust mites), mast cells are stimulated by the allergen and histamine is released. It causes a chain reaction leading to allergic symptoms, as well as an increase in blood flow to the reaction area. As a result, other chemicals are formed that enhance the allergic reaction.
Thus, the release of histamine leads to symptoms of an allergic reaction. With hay fever , inflammation of the skin, eyes, nose, or respiratory tract begins. The eyes are watery and itchy, a person is tormented by a runny nose, swelling in the nose and sneezing. Histamine is responsible for the symptoms of an allergic rash and itching, as well as reactions to individual foods, medications, or insect bites. It can cause more serious forms of allergies, such as Quincke's edema, which includes severe swelling of the eyes, lips, tongue, or throat. Tavegil is capable of blocking the histamine H1 receptors. The instructions to it inform that nothing actually interferes with the actual release of histamine from mast cells, but prevents its binding to receptors. As a result, other chemicals that increase the symptoms of allergies are not produced . Clemastine is called a sedative antihistamine because it enters the brain in significant quantities and causes drowsiness.
In addition to drowsiness, this medicine can provoke visual impairment and dizziness. When treating with Tavegil, one should not work with machinery or drive a car and alcohol must be excluded. If Tavegil is prescribed for children, they should avoid potentially hazardous activities such as cycling or climbing trees. 48 hours before undergoing tests for the diagnosis of allergies, stop taking clemastine. After all, the drug can prevent or reduce skin reactions that indicate an allergen and reduce the reliability of test results.
If, despite treatment, the symptoms persist, then you should consult a doctor. Some people with extreme caution need to take Tavegil. The instruction recommends that you consult with a doctor for older people, those who are diagnosed with liver, kidney, epilepsy, glaucoma, thyroid enlargement, prostate hypertrophy, difficulty urinating (urinary retention), constipation. For children under the age of one year or people with hereditary blood diseases (porphyria), treatment with Tavegil is undesirable. This medicine should not be taken if you are allergic to clemastine or one of its auxiliary components, you should inform your doctor about this.
There are medicines that cannot be used during pregnancy or breastfeeding, while others can be safely used by pregnant women and nursing mothers. Therefore, you must inform your doctor about pregnancy or immediate plans for it. It has not been established that Tavegil is safe during pregnancy. The instruction prescribes to avoid taking it during this period, which is especially important in the first and third trimesters. Clemastine passes into breast milk and may be harmful to the baby, so you should not take the drug to nursing mothers.
Medicines have side effects and affect people in different ways. For example, drowsiness, headache, blurry vision, dry mouth, diarrhea, constipation, vomiting, nausea, and abdominal pain occur. Dizziness, fluid retention, palpitations, tremors, anxiety sleep, and depression are also possible. This is not a complete list of side effects, and also does not mean that they will be experienced by all people using Tavegil. You can read reviews about it, but it is better to read the instructions and use it only as directed by a doctor.
