How Chlorphenamine Tablets Work
Chlorphenamine is a first-generation antihistamine that blocks H1 histamine receptors. By preventing histamine from binding to its receptors, it reduces allergy symptoms such as sneezing, itching, and watery eyes. Its fast action makes it suitable for short-term allergy management under healthcare supervision.
