Truvada is a highly effective antiviral medication used in the treatment and prevention of HIV-1 infection. Each tablet contains 245 mg of tenofovir disoproxil fumarate and 200 mg of emtricitabine, working together to inhibit the reverse transcriptase enzyme critical for viral replication. Truvada is a cornerstone in HIV therapy, often prescribed as part of a combination regimen. It is also approved for pre-exposure prophylaxis (PrEP) to reduce the risk of HIV infection in high-risk individuals. Regular monitoring by a healthcare provider is recommended to ensure optimal efficacy and manage potential side effects.
