Trizivir is indicated for the treatment of HIV-1 infection in adults and children weighing at least 40 kg. It is typically used in patients who have not previously received antiretroviral treatment or in specific treatment scenarios as determined by a healthcare provider.
Trizivir contains three nucleoside reverse transcriptase inhibitors (NRTIs) that work by blocking an enzyme called reverse transcriptase, which HIV needs to multiply. By inhibiting this enzyme, the medication helps reduce the viral load and allows the immune system to recover.
Trizivir carries a boxed warning for serious hypersensitivity reactions associated with abacavir. Prior to starting treatment, patients should be screened for the HLA-B*5701 gene to assess risk. It is not a cure for HIV and must be taken consistently as part of a complete antiretroviral regimen. Common side effects may include nausea, headache, fatigue, and loss of appetite.
