How is emtricitabine/tenofovir disoproxil taken?

Daily dosing is common, while event-based schedules are suitable only for some people and settings. The clinician chooses the schedule and arranges follow-up testing.

What side effects can emtricitabine/tenofovir disoproxil cause?

Can I get a consultation for Emtricitabine/tenofovir from Cádiz?

Yes. Hi-Doctor runs 100 % online across the EU, so if you live in Cádiz you can fill in the questionnaire and receive the medical review without travelling. The electronic prescription issued by the licensed doctor is valid in any EU pharmacy under Directive 2011/24/EU; in Spain it is dispensed directly from the prescription QR.

Is my sexual health consultation fully confidential?

Yes. All communication happens in the private chat of your account, GDPR-compliant. The doctor treats discretion as a core of the service and there is no history visible outside your consultation.

What is the private electronic prescription and why is it valid across the EU?

The private electronic prescription (Receta Médica Privada Electrónica) is issued by a licensed doctor in Spain. It is a PDF carrying every field required by EU Directive 2011/24/EU (patient, prescriber with country of registration, active ingredient, dose), which makes it legally recognised across all 27 EU member states. In Spanish pharmacies it is dispensed from the QR; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.

About

What is Emtricitabine/tenofovir?

Active ingredient: Emtricitabine-tenofovir · Dosages: 200 mg / 245 mg

Emtricitabine with tenofovir disoproxil is an antiviral combination used for HIV pre-exposure prophylaxis (PrEP) in eligible people at higher risk. It is one part of a prevention plan that includes regular HIV and STI testing.

The indication, regimen and follow-up depend on your history and country guidance. A licensed doctor decides whether it is appropriate; prescribing is never automatic.

How it works in the body

Both medicines block reverse transcriptase, an enzyme HIV needs to copy its genetic material after entering a cell.

How it helps

What it can offer when appropriate.

Established PrEP option

The combination is authorised in the EU to reduce sexually acquired HIV risk alongside safer-sex practices.

Monitoring built in

HIV status, kidney function, hepatitis B and STI screening are checked before and during care.

Schedule matched to the person

Daily dosing is common; event-based dosing is only appropriate for specific people and situations.

What to expect

A doctor-defined regimen.

Daily PrEP commonly uses one tablet per day. The doctor decides whether daily or another evidence-based schedule is appropriate and confirms when protection can be relied on.

Before starting · Negative HIV test and baseline checks
During PrEP · Take the agreed schedule consistently
Follow-up · Repeat HIV, kidney and STI checks

Typical regimen

Fixed-dose tablet200 mg / 245 mg
Common scheduleOne tablet once daily

Your schedule is personal

These are typical steps only. Your doctor adjusts the plan to how you respond and tolerate it — and you can message them at any point.

Safety first

Safety, in full.

Emtricitabine/tenofovir is an effective medicine — and like any medicine it carries risks. Your doctor screens for all of this before prescribing. Here's the honest picture, not just reassurance.

Pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 in HIV-negative adults at elevated risk.

One tablet once a day, preferably with food.
Only start after a confirmed negative HIV test — and repeat the test every 3 months while on PrEP.
Protection depends on taking it every day; missed doses lower it substantially.
Keep using condoms — PrEP does not protect against other STIs or pregnancy.

Who should not take it

Anyone who is HIV-positive or whose HIV status is unknown — PrEP alone is not an HIV treatment.
Allergy to emtricitabine, tenofovir or any tablet ingredient.
Significantly reduced kidney function.
Hepatitis-B status should be checked before starting, because of the stopping-flare risk.

When to seek urgent care

For severe, sudden or unexpected symptoms, call your local emergency number or go to the nearest emergency department. Then let your doctor know through your account chat.
