Tenvir-EM Tablets: Active Ingredients, Strength, Uses and Safety Information

Tenvir-EM is an antiretroviral medicine brand associated with a combination of two active ingredients: tenofovir disoproxil fumarate and emtricitabine. These medicines belong to a group called nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs), which act on enzymes that HIV needs to replicate.

The exact formulation, approved indications and availability of Tenvir-EM should be confirmed against the manufacturer's current product information and the applicable regulatory requirements in Singapore. Brand formulations and registration status can differ between countries.

Tenvir-EM Tablets: Active Ingredients and Strength

The commonly documented formulation of Tenvir-EM contains:

Tenofovir disoproxil fumarate: 300 mg

Emtricitabine: 200 mg

These ingredients work together to inhibit HIV replication. Always check the packaging and official product leaflet to confirm the ingredients and strength of the specific product supplied. Do not assume that every product sold under a similar brand name has an identical formulation.

What Are Tenvir-EM Tablets Used For?

Tenofovir and emtricitabine combinations may be prescribed for specific HIV-related indications, depending on the product's approved labelling and local regulations.

In appropriate clinical settings, this combination may be used as part of antiretroviral treatment for HIV-1 infection. It may also be used for HIV pre-exposure prophylaxis (PrEP) in eligible individuals when the product is authorised for that indication and prescribed according to clinical guidelines.

Tenvir-EM is not a cure for HIV. It does not treat every sexually transmitted infection and should not be considered a substitute for medical assessment, testing or other recommended prevention measures.

Potential Benefits of the Active Ingredients

When prescribed for an appropriate indication, the combination offers two active medicines in one tablet. This can simplify a treatment regimen and helps inhibit HIV replication through complementary activity.

For eligible people using an authorised PrEP regimen, tenofovir and emtricitabine can reduce the risk of acquiring HIV when taken as prescribed. PrEP does not protect against other sexually transmitted infections, and its effectiveness depends on correct use and appropriate clinical monitoring.

Individual suitability and expected outcomes must be assessed by a qualified healthcare professional.

Possible Side Effects of Tenvir-EM

Side effects vary between individuals. Possible effects associated with tenofovir disoproxil fumarate and emtricitabine include:

Nausea or vomiting

Diarrhoea

Headache

Dizziness

Tiredness or weakness

More serious but less common risks can include kidney problems, reduced bone mineral density and lactic acidosis. People with hepatitis B may experience a flare of the infection if these medicines are discontinued without appropriate medical supervision.

Seek urgent medical attention for severe or unusual symptoms. Tell your healthcare professional about existing medical conditions and all medicines or supplements you take.

Important Safety Information

Before starting treatment or PrEP, a healthcare professional should assess HIV status and kidney function and determine whether additional testing or monitoring is necessary. People at risk of HIV exposure should discuss testing schedules and appropriate prevention options with a qualified clinician.

Do not start, stop or change the dose without medical advice. If HIV exposure may have occurred recently, seek urgent medical assessment because post-exposure prophylaxis (PEP) is time-sensitive.
