Benadryl is a medication containing a combination of two substances, diphenhydramine and pseudoephedrine and is used in the treatment of various symptoms of allergies and common cold. Diphenhydramine is an antihistamine drug, positively affecting watery eyes, runny nose, sneezing and itching which frequently accompany allergic reactions. The other substance present in Benadryl – pseudoephedrine affects blood vessels in the nose, shrinking them and leading to relief from nasal congestion.
So, this combination of drugs is able to help people suffering from itching, skin rash, hives, cough, sneezing, runny or stuffy nose or some other symptoms related to common cold or allergies.
