Zyrtec - an antihistamine drug of the 2nd generation, has anti-allergic, antipruritic and anti-exudative action. The manufacturer of the drug is the Swiss pharmaceutical company UCB Farchim. Zyrtec is widely used to eliminate allergic reactions and prevent the recurrence of allergies in adults and children. Zyrtec has gained popularity as an effective and reliable drug that can fight allergic pathologies and prevent further progression of the disease.
Allergy - the scourge of modern society. High rhythm of life, constant stress, unhealthy diet, wide distribution of chemicals, environmental pollution - all these factors become provocateurs of allergic reactions. The insidiousness of the disease is that allergies may not manifest themselves for a long time by external symptoms. At the same time, inflammatory reactions continue to progress in the human body, supported by the supply of allergens from the external environment.
Over time, the severity of the pathology increases and can develop from mild food allergies to severe bronchial asthma or lead to other serious health problems. Prevent such complications and are designed to modern and effective drugs, one of which is Zyrtec. Let us consider in more detail what kind of therapeutic effect the drug has, from what Zyrtec helps and how to use it correctly.

Zyrtec - drug action

Zyrtec is antiallergic agent from the group of histamine blockers of the 2nd generation. Its therapeutic effect is the ability to block the production of histamine, which plays a major role in the development of allergic reactions and its main symptoms (skin rashes, itching, allergic rhinitis, conjunctivitis, tearing, swelling and redness of the skin).
In response to the penetration of allergens, the body begins to produce biologically active protective substances (histamine, serotonin), which are mediators of inflammation. The main active ingredient of the drug, cetirizine, prevents the release of large amounts of histamine and suppresses its action, due to which allergic reactions subside.
The drug has a pronounced antipruritic effect, prevents exudate secretion, reduces the permeability of the capillary walls, eliminates edema. In bronchial asthma, the drug prevents the development of bronchospasm.
The main active substance prevents the release of substances that provoke inflammation, stabilizes the state of cell membranes, eliminates smooth muscle spasm.
Allergens practically do not get used to the drug, even with prolonged use. Zyrtec in therapeutic doses does not have a sedative effect and does not cause adverse reactions from the cardiovascular system and other vital organs.
The therapeutic effect after a single dose of the initial dose of the drug comes after 20 minutes, and its effect lasts for a day. After ingestion, the drug is completely absorbed from the gastrointestinal tract and after 1 hour its maximum concentration in the plasma is noted. It is metabolized in small quantities in the liver, excreted mainly by the kidneys unchanged. After stopping the course of treatment, the therapeutic effect of the drug lasts for 3 days.

Application Reviews

Review number 1
    For the third consecutive year, I suffer from pollinosis. In the spring, in the period of flowering of plants, my torment begins. They suffer from allergic rhinitis, their eyes become swollen, itchy and watery, their nose is constantly blocked, some unpleasant dry cough and endless sneezing appear. Tried different drugs, but opted for Zyrtec.
    Before him, she took Suprastin, but after taking the pills was sluggish and inhibited, her head did not work at all, constantly wanted to sleep. There are no such problems with Zyrtec, besides, you need to take the drug only once a day. I usually drink a pill for the night, I feel very good in the morning, but in the evening the allergic manifestations usually increase. We have to take the drug for about 2 weeks, until my plants are fading - allergens. But with Zyrtec, this period is much easier.
Review number 2
    The daughter has food allergies, she is only 4 years old and she does not understand why many tasty things are forbidden for her to eat. Sometimes it can drag away an orange or slowly eat a chocolate bar. As a result, a rash appears immediately, the cheeks turn red, the skin itches and itches, the baby is naughty, not sleeping, and often cries. The doctor prescribed her an antiallergic drug Zyrtec in drops.
    She was afraid that the child would refuse to take them, but the baby drinks them easily, since the solution has a sweetish, rather pleasant taste. We strictly observe the dosage, give the drug only 2 times a day, the result from the treatment is good. If an allergic reaction occurs, then after taking the drops for 3 days, all unpleasant symptoms usually disappear.
    And Zyrtec very much helped out in an unusual situation. At the dacha, the little girl was stung by a bee, her face reddened before her eyes, the child began to choke, and before the ambulance arrived they gave Zyrtec drops to drink and soon she felt better. The doctors said that they did everything right, otherwise anaphylactic shock could be dangerous for life.
