What Is This Medication Used For?

Emtricitabine and tenofovir disoproxil fumarate treats HIV-1 infection in adults. It reduces viral load by preventing the virus from replicating. This combination is not used alone. You must pair it with a third antiretroviral drug.

It helps you achieve undetectable viral loads with consistent use.

How Does Emtricitabine Tenofovir Disoproxil Fumarate Tablet Work?

Both drugs block reverse transcriptase, the enzyme HIV uses to replicate. When this enzyme is inhibited, the virus cannot integrate into human cells. Emtricitabine and tenofovir disoproxil fumarate are chain terminators. They stop the virus from building new genetic material.

Without active viral replication, CD4 cell counts rise. Your immune function recovers.

When Should I Take This Medication?

Take Emtricitabine + Tenofovir disoproxil fumarate once daily at the same time each day. Taking it with food improves tenofovir absorption by up to 26 percent. Set a phone alarm or use a pill organizer to stay on schedule. Missing doses allows viral resistance to develop.

What if I Miss a Dose of Emtricitabine + Tenofovir Disoproxil Fumarate Tablet?

Take your missed dose as soon as you remember. Skip it if it is almost time for your next dose. Do not double-dose to make up for a missed tablet. Missing doses increases the risk of drug resistance.

Get back on your regular schedule immediately.

Report dark urine, swelling in legs, or severe fatigue to your doctor immediately.
