Generic name: Brompheniramine / Phenylephrine
Decon-A is a medicine to relieve sneezing, pressure, runny nose, sinus congestion associated with infections of upper respiratory tract, cold, and allergy. It may also be used by your physician to treat certain other conditions.
It refers to the decongestant and antihistamine combination. The antihistamine blocks histamine effects, which cause allergy symptoms like sneezing, and watery eyes. The decongestant drains nasal and sinus passages, thus relieving pressure and congestion.
