A member asked:

Is it possible for too much decongestant/antihistamine to make my sinuses worse?

A doctor has provided 1 answer

Yes but not likely: Some antihistamines may thicken the mucous. Oral decongestants don't cause much in the way of tolerance. It is more likely that your condition itself has gotten worse or become complicated by infection perhaps.
