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 as a tablet or liquid and is prescribed for both adults and children. While it can help manage HIV and improve the quality of life for those infected, it may also cause side effects, including rash and liver issues, requiring regular monitoring by healthcare providers.
