Tenofovir: Essential Info for HIV and Hepatitis B Treatment

Tenofovir, a medication used to treat HIV and hepatitis B infections. Also known as TDF or TAF, it's a cornerstone of modern antiviral therapy. tenofovir blocks the reverse transcriptase enzyme that viruses use to replicate. Without this enzyme, HIV and hepatitis B can't multiply effectively. It's not a cure, but consistent daily use keeps infections under control. Many people starting treatment wonder how this drug fits into their daily routine, especially when managing long-term conditions.

HIV treatment, a multi-drug approach to control the virus long-term typically combines tenofovir with other antiretrovirals like emtricitabine. This combination creates a powerful regimen that attacks the virus at multiple stages of its life cycle. For example, Truvada (tenofovir + emtricitabine) is a common first-line option. Adherence is critical—missing doses allows the virus to mutate and become resistant. Regular blood tests track viral load and immune health to ensure the treatment stays effective over time.

Hepatitis B, a liver infection that can become chronic often requires tenofovir to suppress viral activity. Unlike acute hepatitis B, which may resolve on its own, chronic cases need ongoing treatment to prevent liver damage, cirrhosis, or cancer. Tenofovir reduces the virus in your blood, lowering inflammation in the liver. Treatment usually continues for years, sometimes lifelong. Side effects like nausea or headaches are manageable for most people, but kidney and bone health need monitoring during therapy.

Drug resistance is a real risk if tenofovir isn't taken consistently. When the virus isn't fully suppressed, it develops mutations that make the drug less effective. For HIV, this often means switching to newer regimens with drugs like dolutegravir. For hepatitis B, tenofovir alafenamide (TAF) offers a safer alternative for some patients, with lower doses and fewer side effects on bones and kidneys. Always follow your doctor's instructions exactly—skipping doses or stopping treatment can compromise future options.
