Indinavir is used along with other medications to treat human immunodeficiency virus (HIV) infection. Indinavir is in a class of medications called protease inhibitors. It works by decreasing the amount of HIV in the blood. Although indinavir does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting the HIV virus to other people.
Indinavir comes as a capsule to take by mouth. It is usually taken every 8 hours (three times a day). Take indinavir at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take indinavir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Take indinavir on an empty stomach, 1 hour before meals or 2 hours after meals, with water, skim or nonfat milk, juice, coffee, or tea. However, if indinavir upsets your stomach, it may be taken with a light meal, such as dry toast or cornflakes with skim or nonfat milk. Talk to your doctor or pharmacist about what foods may be taken with indinavir.
Continue to take indinavir even if you feel well. Do not stop taking indinavir without talking to your doctor.
Your doctor may need to interrupt your treatment if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with indinavir.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
Indinavir is also used sometimes in combination with other medications to treat healthcare workers and other individuals exposed to HIV infection after accidental contact with HIV-contaminated blood, tissues, or other body fluids. Talk to your doctor about the possible risks of using this drug for your condition.
Drink at least 48 ounces (1.5 liters), which is approximately six 8-ounce (240-milliliter) glasses, of water or other liquids every 24 hours.
Talk to your doctor about eating grapefruit and drinking grapefruit juice while taking this medication.
