Reviews

We picked up some feedback from people about Zyrtec:
    Marina. Never faced with food allergies. A week ago, a friend came to visit and treated her with citrus dried fruit. I tried out of interest, because I hadn't done it before. After 15 minutes I started to have a strong itch, I was terribly frightened. With that, she ate very little. Not knowing what to do, I ran to the pharmacy. I was given a choice of several drugs. After a long time studying the instructions, I took a zyrtec. I took the pill right away. After 20 minutes itching and redness stopped bothering me. After this incident, I am very attentive to food, and bypass dried fruit, unfortunately.
    Inna. My son had a cough that did not go for about a month, although he gave medicines, did compresses and other means. In the end, she took the child to a paid pediatrician, where they said that the cause of cough is an allergy. Ascoril was prescribed to open the bronchi and improve breathing, and Zyrtec was prescribed for the treatment of allergies. The course lasted 2 weeks, during which time all the symptoms passed.
    Margo. I give Zyrtec drops to my little son, he suffers from allergies. Generics prefer not to give the child, so as not to save on his health. The original medicinal product is produced according to strict standards, tested auxiliary substances are used, the necessary research has been carried out on it. Zyrtec completely suits me, quickly relieves allergic attacks, did not observe drowsiness in a child.
