Decongestant not effective without antihistamine. Why?
Sometimes I take decongestant to dry up my runny nose but it never works unless I add antihistamine. Isn't the decongestant supposed to do its constrictive duties with or without antihistamine?

A decongestant such as pseudoephedrine often is effective on it's own, but often an antihistamine such as chlorpheniraminemaleate is needed to assist with drying - Often when the runny nose is partly related to an allergic reaction. The older generation antihistamines are effective to assist with drying.
