GENERIC NAME: NEVIRAPINE - ORAL (neh-VYE-ruh-peen)
BRAND NAME(S): Viramune
WARNING: Rarely, nevirapine has caused severe (sometimes fatal) liver problems. Seek immediate medical attention if you develop symptoms of liver problems such as persistent nausea, loss of appetite, vomiting, stomach/abdominal pain, dark urine, pale stools, yellowing eyes/skin, unusual tiredness, rash.
Rarely, nevirapine has also caused serious (sometimes fatal) skin/allergic reactions. Seek immediate medical attention if you have any signs of skin/allergic reactions, including: rash, itching/swelling/redness (especially of the eyes/face), blisters, fever, persistent sore throat, unusual tiredness, mouth sores, severe dizziness, trouble breathing, unusual change in the amount of urine, muscle pain/tenderness/weakness, joint pain.
Women are at increased risk for developing these severe reactions. To help decrease the risk of skin/allergic reactions in all patients, nevirapine is started at a lower dose for the first 14 days. Also, people with higher T-cell counts at the start of nevirapine treatment are at greater risk for liver problems. Therefore, nevirapine is usually only started if the T-cell count is fewer than 250 in women or fewer than 400 in men.
Keep all medical and laboratory appointments so your doctor can monitor how you are responding to nevirapine. The risk of these serious side effects is high in the first 18 weeks and highest during the first 6 weeks of nevirapine treatment. However, these side effects may occur at any time while taking this medication.
If you have stopped taking nevirapine because of liver problems or skin/allergic reactions, you must never take any form of nevirapine again. Tell all of your doctors and pharmacists if you have ever stopped taking nevirapine because of these types of reactions.
