Important safety information:
- Indinavir may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Indinavir with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Indinavir is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
- Indinavir does not stop the spread of HIV to others through blood or sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors.
- When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Indinavir, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
- Indinavir may improve immune system function. This may reveal hidden infections in some patients. Tell your doctor right away if you notice symptoms of infection (eg, fever, sore throat, weakness, cough, shortness of breath) after you start Indinavir.
- Changes in body fat (eg, an increased amount of fat in the upper back, neck, breast, and trunk, and loss of fat from the legs, arms, and face) may occur in some patients taking Indinavir. The cause and long-term effects of these changes are unknown. Discuss any concerns with your doctor.
- Indinavir may raise your blood sugar. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
- Diabetes patients - Indinavir may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using Indinavir. To prevent pregnancy, use an extra form of birth control (eg, condoms).
- Lab tests, including liver function, cholesterol, complete blood cell counts, and CD4 counts, may be performed while you use Indinavir. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Caution is advised when using Indinavir in CHILDREN; they may be more sensitive to its effects, especially kidney stones.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Indinavir while you are pregnant. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or Indinavir to the baby. It is not known if Indinavir is found in breast milk.
