Severe and sometimes fatal liver problems have occurred in patients taking Viramune. The risk of liver problems is greatest during the first 18 weeks of therapy but may occur at any time during treatment. This may occur in men and women, but the risk may be greater in women and in patients with a high CD4 cell count at the start of treatment. Certain pregnant women and women with a CD4 cell count higher than 250 have the greatest risk. Contact your doctor right away if you develop a rash or symptoms of liver problems (eg, dark urine, yellowing of the eyes or skin, pale stools, stomach pain, nausea, loss of appetite, unusual tiredness).
Viramune should only be used in patients who have been diagnosed with HIV. Do not use Viramune to prevent HIV infection if you have been exposed to the virus.
Serious and sometimes fatal skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, and allergic reactions have been reported in some patients taking Viramune. These reactions may also affect other areas of the body (eg, liver, kidneys). The risk of skin reactions is greatest during the first 6 weeks of therapy but may occur at any time during treatment. Contact your doctor right away if you develop blisters or sores in the mouth; fever; general ill feeling; muscle or joint aches; rash, including red, swollen, blistered, or peeling skin; red or swollen eyes; severe tiredness; trouble breathing; swelling of the mouth or face; change in the amount of urine produced; or symptoms of liver problems.

- Hormonal birth control (eg, birth control pills) may not work as well while you are taking Viramune. To prevent pregnancy, use an extra form of birth control (eg, condoms).
- Lab tests, including liver function, heart function, complete blood cell counts, and CD4 cell counts, may be performed while you take Viramune. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
