Nelfinavir (also called Viracept®) is used to treat infection caused by the human immunodeficiency virus (HIV). This medicine is one of a group called protease inhibitors (PIs). Protease is the part of the virus that allows it to multiply, leave the cell, and move into the blood and body. Nelfinavir can slow down how soon you will see symptoms or slow the damage caused by HIV, but it cannot cure HIV infection. This medicine is available as an oral powder and as a 250-mg tablet. Both are taken by mouth.
