What is tenofovir fumarate used for?

Tenofovir fumarate is an antiviral medication primarily used to treat chronic hepatitis B and human immunodeficiency virus (HIV) infection, also known as AIDS. It controls disease progression by inhibiting viral replication. If severe nausea, vomiting, abnormal kidney function, or bone pain occur after taking the medication, medical attention should be sought promptly.

Its mechanism of action involves inhibiting the activity of viral reverse transcriptase, thereby blocking the synthesis of viral nucleic acids. This reduces viral replication and spread within the body, slows liver damage or deterioration of immune function, and helps patients maintain stable disease conditions.

The drug is suitable for adult and eligible adolescent patients with chronic hepatitis B, and can also be used in combination with other antiretroviral drugs for the treatment of AIDS. Medication must be taken strictly according to medical instructions; patients should not discontinue treatment or alter dosages without guidance.

During treatment, patients should maintain regular作息 (daily routines), avoid staying up late, follow a light and easily digestible diet, reduce intake of greasy and spicy foods, regularly monitor kidney function and bone density, avoid concomitant use of nephrotoxic drugs, and adhere to the prescribed treatment course to ensure therapeutic effectiveness.
