Etravirine 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. This medication is usually prescribed to people who have taken other HIV medications (e.g., efavirenz, nevirapine, delavirdine) that did not work well enough to control their HIV. Etravirine is known as a non-nucleoside reverse transcriptase inhibitor (NNRTI). It blocks the virus from growing and infecting more cells.
Etravirine 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.
In children, the dosage is based on weight.
If you have trouble swallowing this medication whole, you may place your dose in a glass with about 1 teaspoonful (5 milliliters) of water to dissolve the tablet. If needed, add more water to cover the tablet. Stir the mixture well until it looks milky. Use only water to dissolve the tablet before adding other liquids. You may then add a small amount of water, orange juice, or milk to the glass and drink all of it right away. Rinse the glass with more water, orange juice, or milk and drink all of it. Rinse and drink several times to make sure you have taken the whole dose. The manufacturer says you should not mix the drug with grapefruit juice, or with warm or carbonated drinks.
It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased.
Do not take 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. Doing so may cause the amount of virus to increase and/or make the infection more difficult to treat (resistant).
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.
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.
As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including: unexplained weight loss, severe tiredness, muscle aches/weakness that doesn't go away, headaches that are severe or don't go away, joint pain, numbness/tingling of the hands/feet/arms/legs, vision changes, signs of infection (such as fever, chills, swollen lymph nodes, 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 trouble breathing/swallowing/moving your eyes, drooping face, paralysis, trouble speaking).
Tell your doctor right away if any of these unlikely but serious side effects occur: increased thirst/urination, signs of kidney problems (such as change in the amount of urine), mental/mood changes (e.g., nervousness, confusion), seizures.
Get medical help right away if any of these rare but very serious side effects occur: chest/jaw/left arm pain.
Changes in body fat may occur while you are taking this medication (e.g., 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 role of exercise to reduce this side effect.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Etravirine can commonly cause a mild rash that is usually not serious. The rash usually occurs during the second week of treatment and goes away in 1 to 2 weeks. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe allergic reaction. Therefore, get medical help right away if you develop any rash, especially with symptoms such as fever, tiredness, muscle/joint pain, blisters, mouth sores, or red/swollen eyes.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
