Tafnat Tablet is a prescription antiviral medicine containing Tenofovir Alafenamide 25 mg, which belongs to the class of nucleotide reverse transcriptase inhibitors (NRTIs). It is primarily used for the treatment of chronic Hepatitis B infection in adults with compensated (stable) liver disease. In certain cases, it may also be included as part of combination therapy for HIV-1 infection, depending on the patient’s condition and medical guidance.
Common side effects of Tafnat Tablet include headache, nausea, diarrhea, abdominal discomfort, joint pain, and indigestion, which are generally mild and temporary. However, if these symptoms persist or worsen, medical advice should be sought. Before starting treatment, patients should inform their doctor about any liver, kidney, or existing health conditions, and regular monitoring through blood tests may be required. Alcohol should be avoided due to the risk of liver damage, and pregnant or breastfeeding women should consult a doctor before use. Practicing safe habits, including avoiding the sharing of personal items and using protection, is important to reduce the risk of infection transmission.
Tafnat Tablet contains Tenofovir Alafenamide (TAF), which is a prodrug of tenofovir. After being absorbed, TAF is converted inside liver cells into its active form, tenofovir diphosphate. This active form works by inhibiting the enzyme reverse transcriptase, which is essential for the replication of the hepatitis B virus (HBV). By blocking this enzyme, the medicine prevents the virus from multiplying, reduces viral load in the blood, and helps slow down liver damage. Compared to older forms of tenofovir, TAF delivers the drug more efficiently to the liver, with lower risk of kidney and bone side effects.
