Sustiva, also known by its generic name efavirenz, is a medication commonly used in the treatment of HIV infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which work by blocking an enzyme needed by the virus to replicate.

Sustiva is typically prescribed in combination with other antiretroviral medications to effectively manage HIV and reduce the viral load in the body. It is important to take Sustiva exactly as prescribed by your healthcare provider, as missing doses or not following the recommended dosing schedule can lead to treatment failure and the development of drug-resistant strains of the virus.

Like all medications, Sustiva can cause side effects. Common side effects may include dizziness, drowsiness, trouble sleeping, and vivid dreams. These side effects usually improve over time as your body adjusts to the medication. However, if you experience severe or persistent side effects, it is important to contact your healthcare provider.

It is also important to note that Sustiva can interact with other medications, including over-the-counter drugs and herbal supplements. Before starting Sustiva, make sure to inform your healthcare provider about all the medications and supplements you are currently taking to avoid any potential drug interactions.

Overall, Sustiva is an important medication in the treatment of HIV infection and can help individuals living with the virus lead healthier and longer lives. If you have any questions or concerns about Sustiva or your HIV treatment plan, do not hesitate to reach out to your healthcare provider for guidance and support.
