Answer

An analgesic is a painkiller.  An antihistamine is to prevent an allergic reaction.  A muscle relaxant, a decongestant.... there are so many.

Answer

You can use all of those!  Another way to describe types of medicine would be their category, like:  antacid, anti-inflammatory, antibiotic, sedative, etc.  "I need an antacid, my stomach is killing me."  "I can't sleep, I wish I had some kind of sedative."
