Today, various types of allergies are quite common. There are many reasons for the development of allergic reactions: food, plant pollen, household dust, pets, insect bites, medications. It is important to start timely treatment when a reaction is detected. Therapy is carried out through the use of antihistamines. Zyrtec is very popular. Zyrtec tablets and drops are second-generation drugs, which means they have fewer contraindications and adverse reactions.
Zyrtec tablets
Antihistamine tablets of the second generation Zyrtec have the following effect for allergies:
- Anti-inflammatory;
- Antipruritic;
- Anti-exudative.
Zyrtec blocks the release of histamine from mast cells. The drug does an excellent job in the treatment of allergic reactions, and is also used for preventive purposes. Also, tablets significantly reduce the area of migration of the allergen throughout the body. With the timely use of the drug, it helps to avoid the development of edema of the mucous membranes and tissues. Zyrtec is aimed at eliminating the skin manifestations of allergies.
The sedative effect from the use of Zirtek is very rare. Therefore, the drug is approved for use by people whose activities are associated with concentration, physical and mental stress. The active substance is cetirizine chloride. The result becomes noticeable after half an hour after taking the pill. The effect persists for at least a day. Absorption occurs through the digestive system almost completely. It is worth noting that the use of Zirtek can be independent of food intake.
In a small amount, the drug takes part in metabolic processes in the liver. Removal of Zirtek in adults occurs after 10 hours. Instructions for use indicate that most of the drug is excreted by the kidneys unchanged. In children, excretion occurs much earlier - from 3 to 6 hours. With problems with the liver and in the elderly, the absorption and excretion of the drug takes a long time. Therefore, in some cases, the dosage should be increased.
Zyrtec tablets are used by children from the age of six. If an allergy struck a young child, use similar drops. Adults take 10 mg tablets once a day. Children should be given 5 mg twice a day. If the desired result is not achieved at a dosage of 5 mg, it can be increased to 10 mg. In case of renal or hepatic insufficiency, the treatment regimen is adjusted only by the doctor.

Drops Zyrtec for allergies
This drug has the form of not only tablets, but also drops. The use of Zyrtec in this form occurs orally (internal use). Drops have cetirizine dihydrochloride as an active substance. Drops create a certain barrier to re-penetration of the allergen into the body. It also neutralizes already existing pathogenic microorganisms.
This form of Zyrtec significantly reduces the sensitivity of the bronchial and entire respiratory system to external and internal stimuli. The maximum concentration and action of the agent is observed an hour after application. Drops of this drug are excreted after 6-10 hours through the kidneys along with urine. In children, this process is a little faster. It should be noted that the agent has practically no effect on liver function and metabolic processes in this organ.
