Short General Description of Sustiva

Sustiva, also known as efavirenz, is a highly effective antiviral medication specifically designed for the treatment of HIV. This medication is classified under a group of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs).
NNRTIs work by targeting and inhibiting the reverse transcriptase enzyme, which is essential for the replication of HIV. By doing so, Sustiva prevents the virus from multiplying, reducing its impact on the immune system.
Here are some key points to understand about Sustiva:
1. Mode of Administration: Sustiva is predominantly available in oral form, commonly taken as a single tablet once daily. It is crucial to follow the prescribed dosage and instructions provided by your healthcare professional.

Common side effects include dizziness, trouble sleeping, headache, nausea, and rash. It is important to report any side effects to your healthcare provider to ensure appropriate management.
5. Drug Interactions: Sustiva can potentially interact with other medications, including over-the-counter drugs, prescription medications, and herbal supplements. It is crucial to inform your doctor or pharmacist about all the medications you are currently taking to prevent any potential interactions or adverse effects.
6. Special Considerations: Sustiva may not be suitable for everyone, particularly those with a known hypersensitivity to efavirenz or any of the components in the formulation. People with a history of mental health disorders or severe liver disease should exercise caution and consult with their healthcare provider before initiating treatment with Sustiva.
It is important to note that Sustiva is a prescription medication and should only be used under the guidance and supervision of a qualified healthcare professional. Regular monitoring and follow-up visits are important to ensure the effectiveness and safety of the treatment.
For more detailed information on Sustiva, you can refer to reputable sources such as the National Institute of Health’s AIDSinfo or consult with your healthcare provider.
