What is the difference between tenofovir alafenamide fumarate tablets/Veride and whether it is imported or domestically produced?

Tenofovir alafenamide/Veridex (TAF) is a prescription medicine used to treat chronic (persistent) hepatitis B virus (HBV) in adults with stable (compensated) liver disease. Tenofovir alafenamide fumarate tablets may reduce the HBV content in patients, and may also improve the patient's liver condition. Tenofovir alafenamide is a small tablet that is taken once a day with food. Patients should not stop taking this medicine unless told by their doctor; this is because HBV infection in the body may worsen (sudden attack) if the medicine is stopped suddenly. A "flare" is when the HBV virus infection suddenly returns in a worse way than before.
