Nevirapine is an antiretroviral medication used to treat HIV infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which work by blocking the reverse transcriptase enzyme, preventing the virus from replicating in the body. Nevirapine is often used in combination with other antiretroviral medications to enhance its effectiveness. This medication is typically taken orally, either as a tablet or liquid, and is usually prescribed for adults and children over the age of two months. While Nevirapine can help manage HIV, it may cause side effects, including rash and liver issues, so regular monitoring by a healthcare provider is essential.
