emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate at a glance
Medicine class
Combination antiretroviral containing two nucleotide or nucleoside reverse-transcriptase inhibitors and the NNRTI rilpivirine.
Licensed role
Treatment of selected adults with HIV-1, guided by viral load and resistance information.
Food
Take with food; a nutritional drink alone is not an adequate substitute.
Tablet handling
Swallow whole with water; do not chew, crush or split.
What is emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate used for?
Licensed for HIV treatment, not HIV prevention or treatment of chronic hepatitis B alone.
Treatment of HIV-1 infection in selected adults without known resistance mutations affecting the NNRTI class, tenofovir or emtricitabine.
Resistance testing or documented historical resistance results should guide selection.
How does emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate work?
Rilpivirine blocks HIV reverse transcriptase non-competitively. Activated emtricitabine and tenofovir compete with natural building blocks and terminate developing viral DNA chains. Together they reduce HIV replication but do not eliminate the virus.

How to take emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate
Follow the schedule prescribed by the HIV team. Take the tablet with food and swallow it whole with water; do not chew, crush or split it. A nutritional drink alone does not replace food.
Check with a pharmacist before using indigestion or acid-reducing treatments; proton-pump inhibitors are contraindicated.
Do not stop or restart treatment without consulting the HIV team, particularly if hepatitis B is also present.

emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate in pregnancy
Available data have not identified malformative or fetal toxicity from the individual components, and the combination may be considered when necessary. Rilpivirine exposure can fall during pregnancy, so specialist review and close viral-load monitoring are important. Do not stop prescribed treatment without specialist advice.
emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate while breastfeeding
The product information instructs women not to breastfeed while receiving this combination. Emtricitabine and tenofovir enter breast milk, infant effects are insufficiently characterised, and HIV can be transmitted through milk. UK practice considers formula feeding safest; anyone wishing to breastfeed should discuss this early with the specialist perinatal HIV team.
emtricitabine + rilpivirine hydrochloride + tenofovir disoproxil fumarate interactions
Rilpivirine absorption and CYP3A metabolism create important interactions, while tenofovir can add to kidney toxicity.
Proton-pump inhibitors, including omeprazole and lansoprazole
Contraindicated because they can substantially reduce rilpivirine exposure and compromise HIV control.
Antacids and H2-receptor antagonists
Can reduce rilpivirine absorption and require separation as directed by the prescriber or pharmacist.
Carbamazepine, oxcarbazepine, phenobarbital or phenytoin
Contraindicated because they can lower rilpivirine concentrations and undermine treatment.
