Generic name: Pseudoephedrine / Dexchlorpheniramine
Hexafed is a medicine to relieve running nose, itchy or watery eyes, congestion, itchy nose or throat, sneezing, associated with allergy, hay fever, flu, or cold. 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.
