Aptivus (generic: tipranavir) is a prescription medication used to treat Human Immunodeficiency Virus (HIV) in adults.  Aptivus belongs to a group of drugs called protease inhibitors, which limit the production of new viruses. 

This medication comes in capsule and liquid forms and is taken twice a day. Aptivus is always taken with Norvir (ritonavir), another HIV medication, and at the same time as Norvir. Norvir increases the level of Aptivus in the blood, helping Aptivus to work better. 

Common side effects of Aptivus include diarrhea, nausea, headache, and fatigue.
