LEVOCETIRIZINE+AMBROXOL is a combination respiratory medication used to treat symptoms associated with chronic bronchitis, chronic obstructive pulmonary disease (COPD), allergic rhinitis, and respiratory tract infections, such as cough, sneezing, runny nose, and watery eyes. It consists of Levocetirizine (anti-histamine) and Ambroxol (mucolytic agent). Levocetirizine is an antihistamine (anti-allergic) drug that reduces the effects of histamine, a chemical substance that causes allergies like runny nose and skin rash. Ambroxol is a mucolytic agent and an expectorant that works by thinning and loosening phlegm (mucus) in the lungs, windpipe and nose.
