What is indinavir?
Indinavir is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults. Indinavir is always used in combination with other anti-HIV medicines.
Indinavir is a type of anti-HIV medicine called a protease inhibitor (PI). Indinavir works by blocking protease, an HIV enzyme. This prevents HIV from replicating and lowers the amount of HIV in the blood.
Indinavir does not cure HIV/AIDS. It is not known if indinavir reduces the risk of passing HIV to other people.
What should I tell my health care provider before taking indinavir?
Before taking indinavir, tell your health care provider:
- If you are allergic to indinavir or any other medicines.
- If you have liver problems, especially mild or moderate liver disease caused by cirrhosis (scarring of the liver).
- If you have kidney problems.
- If you have diabetes.
- If you have hemophilia.
- If you have high cholesterol and are taking cholesterol-lowering medicines called “statins.”
- If you are pregnant or plan to become pregnant. Whether indinavir can harm an unborn baby is unknown.
- If you are breastfeeding or plan to breastfeed. Do not breastfeed if you are infected with HIV or are taking indinavir.
- About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Indinavir may affect the way other medicines or products work, and other medicines or products may affect how indinavir works. Taking indinavir together with certain medicines or products may cause serious and/or life-threatening side effects.
How should I take indinavir?
Indinavir comes in three strengths:
- 100-mg capsules (brand name: Crixivan).
- 200-mg capsules (brand name: Crixivan).
- 400-mg capsules (brand name: Crixivan).
Take indinavir according to your health care provider’s instructions.
Take indinavir capsules every 8 hours around the clock, every day. Take indinavir with water (or other beverage such as skim or nonfat milk, juice, coffee, or tea) at least 1 hour before or 2 hours after a meal. Or you can take indinavir with a light meal that is low in calories, fat, and protein. Drink at least six 8-ounce glasses of liquids (preferably water) throughout the day to reduce the risk of kidney stones.
Always take indinavir in combination with other anti-HIV medicines.
If you take too much indinavir, contact your local poison control center (1-800-222-1222) or go to the nearest hospital emergency room right away.

What should I do if I forget a dose?
If you miss a dose by more than 2 hours, wait and then take the next dose at the regularly scheduled time. If you miss a dose by less than 2 hours, take the missed dose immediately. Then take your next dose at the regularly scheduled time. Do not take more or less than your prescribed dose of indinavir at any one time.
