Diphenhydramine+Phenylpropanolamine is used in the treatment of common cold.

Diphenhydramine + Phenylpropanolamine is a combination of two medicines: Diphenhydramine and Phenylpropanolamine which relieve common cold symptoms. Diphenhydramine is an antiallergic which relieves allergy symptoms like runny nose, watery eyes and sneezing. Phenylpropanolamine is a decongestant which narrows the small blood vessels providing relief from congestion or stuffiness in the nose.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
