Overview
MyTaff 25mg (Tenofovir Alafenamide) Tablet contains tenofovir alafenamide 25mg, a nucleotide reverse transcriptase inhibitor used, as part of a combination antiretroviral regimen, in the treatment of HIV infection, and also used on its own to treat chronic hepatitis B infection in adults. This is a specialist-prescribed medicine requiring ongoing supervision by an infectious disease physician or hepatologist.
Tenofovir alafenamide is a prodrug that is taken up into cells and converted to tenofovir diphosphate, which is incorporated into the viral DNA chain by the reverse transcriptase enzyme of HIV or the polymerase enzyme of hepatitis B virus. This incorporation terminates the growing DNA chain, halting viral replication and allowing the immune system to gain better control of the infection.
How it Works
After entering cells, tenofovir alafenamide is hydrolysed and phosphorylated to its active form, tenofovir diphosphate, which competes with the natural building blocks of DNA. When incorporated by the viral reverse transcriptase (HIV) or polymerase (hepatitis B virus) enzyme, it lacks the chemical group needed to continue the DNA chain, causing chain termination and preventing the virus from replicating.
Directions for Use
Take MyTaff 25mg (Tenofovir Alafenamide) Tablet once daily with food, at the same time each day, exactly as prescribed. Strict daily adherence is essential – never skip, delay, or stop doses on your own, as inconsistent use can allow the virus to develop resistance to this medicine and to other antiretrovirals in the same class.
Dosage
The usual dose of MyTaff 25mg (Tenofovir Alafenamide) Tablet is one tablet once daily, taken as part of your prescribed treatment plan. Your specialist doctor determines the exact regimen, including any other medicines to be combined with it, based on your diagnosis, viral load, and kidney/liver function – never adjust the dose or combination yourself.

Frequently Asked Questions
What is MyTaff 25mg (Tenofovir Alafenamide) Tablet used for?
MyTaff 25mg (Tenofovir Alafenamide) Tablet is used, together with other medicines, to treat HIV infection, and is also used on its own to treat chronic hepatitis B infection. It is prescribed and monitored by a specialist doctor.
Why is strict daily adherence so important with this medicine?
Missing or delaying doses allows the virus to replicate at levels where it can develop resistance to tenofovir alafenamide and potentially to other medicines in the same drug class, making future treatment more difficult. Taking every dose on schedule is essential for this medicine to keep working.
Can I stop this medicine if I feel well and my hepatitis B seems controlled?
No, do not stop without your specialist’s guidance. Stopping treatment for chronic hepatitis B can cause a sudden flare-up of liver inflammation, which can be serious. Your doctor will advise if and how treatment can ever be adjusted.
What monitoring will I need while taking this medicine?
Your specialist will arrange regular blood tests to check your kidney function, liver function, and, if you are being treated for HIV, your viral load and CD4 count, to make sure the medicine is working and being tolerated well.
Can I adjust my own dose if I miss taking my tablet?
No, never self-adjust. If you miss a dose, follow the specific instructions your doctor or pharmacist has given you, and contact your care team if you are unsure, since correct dosing is critical to prevent resistance.
