Duovir - Lamivudine & Zidovudine 450 mg Tabs

Lamivudine and Zidovudine both belong to a class of antiretroviral drugs known as nucleoside reverse transcriptase inhibitors (NRTIs), which work by interfering with an enzyme HIV needs to copy its genetic material. When combined, these two medications target viral replication through complementary mechanisms, helping to more effectively lower the amount of virus in the blood. This reduction in viral load allows the immune system a better opportunity to recover, often reflected in improved CD4 cell counts over time. The combination is typically used alongside a third antiretroviral agent, such as an NNRTI or protease inhibitor, as part of a complete highly active antiretroviral therapy (HAART) regimen. It is generally taken orally, usually twice daily, and adherence to the prescribed dosing routine is important for maintaining viral suppression and reducing the risk of resistance. Regular monitoring, including blood tests to check viral load, CD4 counts, and complete blood counts, is typically recommended throughout treatment. Many patients on this combination achieve meaningful and sustained control of HIV infection with consistent use. As with all antiretroviral therapies, treatment should be guided by a healthcare provider familiar with the patient's overall health and treatment history.
