indinavir Oral Warnings
indinavir Oral Uses
This drug is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life.
Indinavir belongs to a class of drugs known as protease inhibitors. It may be given with ritonavir, another protease inhibitor, to increase ("boost") the levels of indinavir. This helps indinavir work better.
Indinavir is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
This medication may also be used in combination with other HIV medications to reduce the risk of getting HIV infection after contact with the virus. Consult your doctor for more details.How to use indinavir Oral
Read the Patient Information Leaflet provided by your pharmacist before you start taking indinavir and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) on an empty stomach (at least 1 hour before or 2 hours after food), usually 3 times daily or as directed by your doctor. If upset stomach occurs, you may take it with other liquids (such as non-fat milk, apple juice, coffee, tea) or with a light meal (such as dry toast with jelly, corn flakes with non-fat milk and sugar). Avoid taking this medication with a meal high in calories, fat, and protein since this may decrease its effect. If you are directed to take ritonavir with this medication, take them both at the same times.
To help decrease the risk of kidney stones while taking indinavir, drink at least 6 full glasses (8 ounces or 240 milliliters each) of water or other liquids throughout the day.
This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.
It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not take more or less of this drug than prescribed or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat, or worsen side effects.
indinavir Oral Side Effects
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Some people may experience worsening of a previous medical condition (such as an old infection) as their immune systems improve, or develop new conditions because their immune systems have become overactive. This reaction may occur at any time (soon after starting HIV treatment or many months later). Tell your doctor right away if you have any serious side effects, including: unexplained weight loss, persistent muscle aches/weakness, joint pain, numbness/tingling of the hands/feet/arms/legs, severe tiredness, vision changes, severe/persistent headaches, signs of infection (such as fever, chills, trouble breathing, cough, non-healing skin sores), signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter), signs of a certain nerve problem known as Guillain-Barre Syndrome (such as difficulty breathing/swallowing/moving your eyes, drooping face, paralysis, slurred speech).
Tell your doctor immediately if any of these unlikely but serious side effects occur: yellowing eyes/skin.
Seek immediate medical attention if any of these rare but serious side effects occur: symptoms of a heart attack (such as chest/jaw/left arm pain, shortness of breath, unusual sweating), easy bruising/bleeding, persistent nausea/vomiting, stomach/abdominal pain, dark urine, decrease in the amount of urine.
Indinavir may cause kidney stones. Tell your doctor immediately if you have symptoms such as side or mid-back pain, pink/bloody urine, or pain with urination.

Tell your doctor immediately if you develop symptoms of high blood sugar such as increased thirst and urination. If you already have diabetes, check your blood sugar levels regularly. Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Changes in body fat may occur while you are taking this medication (such as increased fat in the upper back and stomach areas, decreased fat in the arms and legs). The cause and long-term effects of these changes are unknown. Discuss the risks and benefits of treatment with your doctor, as well as the possible use of exercise to reduce this side effect.
