Forstavir-EM Tablet contains a combination of Emtricitabine 200mg and Tenofovir disoproxil fumarate 300mg, which are antiretroviral medications used in the treatment of Human Immunodeficiency Virus (HIV) infection. Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) that works by blocking the reverse transcriptase enzyme, essential for viral replication, thereby reducing the amount of HIV in the body. Tenofovir disoproxil fumarate is a nucleotide reverse transcriptase inhibitor (NtRTI) that also inhibits the reverse transcriptase enzyme, preventing the virus from multiplying and helping to improve immune function. Forstavir-EM is prescribed as part of combination antiretroviral therapy (ART) to manage HIV-1 infection in adults and adolescents weighing at least 35 kg. It helps to decrease viral load, increase CD4 cell counts, and delay the progression of HIV-related disease. This medication is not a cure for HIV but helps control the infection and reduce the risk of transmission. Patients should take Forstavir-EM exactly as prescribed, and regular monitoring of kidney function and viral load is recommended. Common side effects may include headache, nausea, fatigue, and gastrointestinal discomfort. It is important to consult a healthcare professional before starting or stopping therapy.
