Tenvir 300mg Tablet contains Tenofovir disoproxil fumarate, a widely used antiviral medicine for managing chronic hepatitis B (HBV) and HIV infections. It belongs to the NRTI (nucleoside reverse transcriptase inhibitor) class and helps control viral replication, reduce viral load, and support the immune system, thereby lowering the risk of disease progression and long-term complications.
Tenvir works by blocking the reverse transcriptase enzyme required by the virus to multiply, effectively slowing the spread of infection in the body. While generally well tolerated, some patients may experience mild side effects such as nausea, headache, dizziness, or fatigue. In rare cases, kidney problems, bone loss, liver issues, or lactic acidosis may occur, so regular monitoring and immediate medical attention for unusual symptoms are important during treatment.
Tenofovir is an antiretroviral medicine from the nucleotide reverse transcriptase inhibitor (NtRTI) class that works by blocking the reverse transcriptase enzyme needed by HIV and hepatitis B viruses to multiply. Tenvir, which contains tenofovir disoproxil fumarate, is converted in the body into its active form, tenofovir diphosphate, which interferes with viral DNA formation and stops further replication. By reducing viral load, it helps control infection, protect the immune system, and limit virus-related damage.
