Tipranavir is one of a new class of HIV protease inhibitors called dihydropyrones or non-peptidic protease inhibitors. It is designed to be active against HIV strains that have become resistant to other protease inhibitors. For this reason it is most useful in salvage or multiple-treatment experienced regimens.

Like most anti-HIV drugs, tipranavir must be taken in combination with other drugs to be completely effective. Commonly, tipranavir is combined with one other nucleoside (NRTI) drug and either a protease inhibitor or non-nucleoside, although other combinations are sometimes used. Your doctor will advise you on the right combination of drugs to suit your circumstances.

All drugs can produce side effects in some people. These may be mild, moderate or severe, so you should be aware of potential side effects before starting any drug, and speak to your doctor if you experience side effects that concern you.
- Common side effects may include nausea (upset stomach, feeling sick to the stomach), diarrhoea, vomiting, headache, fatigue, stomach pain.
- Less common side effects may include rash or sensitivity to the sun, joint pain or stiffness, itching, tightness in the throat..
- Rare side effects may include hepatitis, increases in cholesterol and triglycerides (blood fats), liver failure.
It's unlikely you will experience all of these side effects, and you may not experience any side effects at all. Before starting any new drug, ask your doctor about side effects you might experience and discuss strategies for dealing with side effects if they do occur. If you experience any significant side effect you should continue taking your medicine and see your doctor as soon as possible.

The herb St. John's Wort lowers the blood levels of some protease inhibitors. Do not take it while taking tipranavir.
