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

Ephedrine + Diphenhydramine is a combination of two medicines: Ephedrine and Diphenhydramine. Ephedrine is a decongestant. It narrows the small blood vessels in your nose. This relieves congestion or stuffiness in your nose. Diphenhydramine is an antiallergic which relieves allergy symptoms like runny nose, watery eyes and sneezing.

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
