Tenofovir Alafenamide is this NRTI thingy that’s used to treat chronic hepatitis B and HIV. It stops the enzyme called reverse transcriptase, which is a big deal for virus. The drug comes in these 25 mg tablets with a coating.
You’re supposed to take 25 mg of this stuff once a day, and make sure to eat something with it. They usually come in bottles with 30 tablets inside.
