Children's Zyrtec Hives Relief syrup (equal to Children's Zyrtec Allergy syrup, except it is labeled for hives, not for allergies).
As mentioned, allergies occur when the body's immune system reacts to normally harmless substances that do not bother most people. This reaction is partly caused by the release of histamine from certain cells in the body. Zyrtec blocks histamine from binding to histamine receptors and causing allergy symptoms. Since histamine is responsible for many of the symptoms of allergies, blocking it can be helpful. It is important to note that antihistamines (including Zyrtec) do not help treat nasal congestion caused by allergies, since this symptom is not due to histamine.
PRESCRIBED FOR: Cetirizine is used by people who suffer from allergic symptoms such as sneezing, itchy nose (allergic rhinitis) and itchy eyes. It also has been used to treat hives.
