Phenylephrine+Menthol+Diphenhydramine+Chlorpheniramine Maleate is used in the treatment of dry cough.

Phenylephrine + Menthol + Diphenhydramine + Chlorpheniramine Maleate is a combination of four medicines: Phenylephrine , Menthol , Diphenhydramine and Chlorpheniramine Maleate. Phenylephrine is a decongestant which narrows the small blood vessels providing relief from congestion or stuffiness in the nose. Menthol produces a sensation of coolness and relieves minor throat irritation. Diphenhydramine and Chlorpheniramine are antiallergics which relieve 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
