General Info

Viramune is an HIV medication. It is in a category of HIV medicines called non-nucleoside reverse transcriptase inhibitors.

Viramune was approved by the U.S. Food and Drug Administration for use by people living with HIV in 1996.

Side Effects

The U.S. Food and Drug Administration (FDA) recommends that women with CD4 counts over 250 and men with CD4 counts over 400 should not take Viramune as their first antireflective (ARV) regimen unless the benefits outweigh the risks. This is because Viramune can lead to serious liver problems in people with higher CD4 counts who start Viramune for the first time. This is especially true in pregnant women with higher CD4 counts. People whose CD4 counts have significantly increased from taking another ARV regimen (to greater than 250 in women and 400 in men) may can safely switch to Viramune, however.

In rare cases, liver problems can be very serious and become life-threatening. Therefore, if you develop any of the following symptoms while taking Viramune, call your doctor immediately: general ill feeling, tiredness, lack of appetite, yellowing of the skin or eyes, darkening of the urine, pale stools, liver tenderness.

The most common side effect of Viramune is skin rash. In a small number of patients, rash has been serious and resulted in death. Therefore, if you develop a rash with any of the following symptoms, call your doctor immediately: general ill feeling, fever, muscle or joint aches, blisters, mouth sores, conjunctivitis (inflammation of the inner surface of the eyelids), swelling of the face, tiredness.

If you must stop treatment with Viramune because you have these types of serious reactions, you must not take Viramune again.
