Tenvir Tablets Strengths and Composition

The commonly used strength of tenofovir disoproxil fumarate tablets is 300 mg. The exact strength and composition of the Tenvir product offered by a supplier should be confirmed using the manufacturer's approved product information.

Tenofovir disoproxil fumarate is a prodrug converted into tenofovir in the body. It interferes with viral replication, helping reduce viral activity when used for an appropriate indication.

Important: Do not confuse tenofovir disoproxil fumarate with tenofovir alafenamide (TAF), or with combination medicines containing emtricitabine and tenofovir. These formulations have different compositions and may have different dosing requirements.

Medical Uses and Potential Benefits

Tenofovir disoproxil fumarate may be prescribed for:

Chronic hepatitis B: Helps suppress hepatitis B virus replication and manage the infection.

HIV-1 infection: Used in combination with other antiretroviral medicines as part of an appropriate treatment regimen.

Potential benefits include reducing viral activity, supporting long-term disease management and helping prevent complications associated with uncontrolled infection. The response depends on the patient's condition, adherence to treatment and clinical monitoring.

Tenvir should be used only for an appropriate medical indication under the guidance of a qualified healthcare professional. It is not a cure for HIV or hepatitis B.

Tenvir Tablets Side Effects

Possible side effects of tenofovir disoproxil fumarate include:

Nausea or vomiting

Diarrhoea

Abdominal discomfort

Headache

Fatigue

More serious risks can include kidney problems, reduced bone mineral density and, rarely, severe complications involving lactic acid buildup or liver enlargement.

Patients may require kidney-function monitoring and other tests during treatment. Tell your healthcare professional about existing kidney or liver conditions, pregnancy, breastfeeding and all other medicines or supplements you use.

Do not stop treatment without medical advice. Stopping tenofovir in people with hepatitis B can cause the infection to flare up.
