How long does it take to take tenofovir alafenamide fumarate tablets/viride for normal liver function?

Tenofovir alafenamide/Veridef (TAF) is approved for the treatment of HIV and hepatitis B (HBV) virus infections. Clinical indications include the treatment and prevention of human immunodeficiency virus (HIV) infection, often in combination with other reverse transcriptase, protease or integrase inhibitors. Tenofovir alafenamide tablets marketed as 25 mg tablets under the brand name Vemlidy, are also available in various fixed combinations with other antiviral drugs for the treatment of HIV infection. They are usually provided in a single oral daily dose. This is often referred to as a "single tablet regimen" (STR) and is very helpful in ensuring compliance with HIV treatment.

The main function of tenofovir alafenamide fumarate tablets is to inhibit viral replication, thereby reducing liver inflammation and damage. However, the drug itself may also have certain effects on the liver, leading to abnormal liver function. The recommended daily dose is25 mg, with lower doses considered important to reduce long-term side effects, particularly effects on phosphate metabolism and bone and kidneys. Common side effects include gastrointestinal reactions (such as diarrhea, nausea, vomiting, etc.) and neurological abnormalities (such as headache, dizziness, etc.). In addition, other adverse reactions such as rash, joint swelling and pain, skin itching, and physical fatigue may also occur.

After taking tenofovir alafenamide fumarate tablets, the time it takes for liver function to return to normal varies among individuals and depends on the severity of the disease, liver function status before treatment, virus replication and other factors. Generally speaking, if the disease is mild and the liver function damage is not serious, then the liver function may gradually return to normal within a few months under the influence of drugs. But if the condition is severe and liver function damage is severe, the recovery time may be longer.
