What is Levocetirizine?
Levocetirizine is an antihistamine used for the treatment of allergic rhinitis and long-term hives of unknown causes, marketed under the brand name Xyzal, among others. It is less sedative than antihistamines which are older. It is swallowed by mouth. Sleepiness, dry mouth, cough, vomiting, and diarrhea are common side effects.
Levocetirizine uses
Levocetirizine is an antihistamine that is used for alleviating symptoms of some allergies, such as watery eyes, runny nose, eye/nose itching, and sneezing. It is sometimes used to alleviate hives and scratching. It works by blocking a certain natural substance that your body produces during an allergic reaction (histamine).
Levocetirizine does not deter or prevent or treat extreme allergic reactions (such as anaphylaxis). Always bring your epinephrine injector with you if your doctor has prescribed epinephrine to treat allergic reactions. In place of epinephrine, do not try to use levocetirizine.
