Aller-Chlor

Aller-Chlor contains chlorpheniramine maleate, a first-generation antihistamine. It works by blocking histamine, a substance in the body that causes allergic symptoms. It is commonly used for temporary relief of sneezing, runny nose, and itchy eyes associated with allergies or the common cold, and can cause drowsiness.
