Pre-exposure prophylaxis, also known as PrEP for short, is a medicine that can prevent people from contracting HIV. This medication is taken by people who don’t have human immunodeficiency virus (HIV) but are at high risk for being exposed, or coming into contact with, the virus. 

PrEP blocks the enzymes, or proteins in the blood, that allow HIV to multiply. To block these enzymes, you must build up enough PrEP in your bloodstream. Once PrEP has reached a certain level in your bloodstream, it can prevent HIV from replicating in your body.
