💊 Reliable protection: PrEP provides effective protection against HIV - if taken correctly.

💬 Available on prescription: The costs are covered by health insurance.

🩺 Rare side effects: Mostly mild, regular checks provide security.

📆 Flexible intake: Daily or occasionally - depending on your sex life.

What is PrEP?

PrEP stands for Pre-exposure prophylaxis - a preventive HIV medication. It blocks the virus before it can spread in the body. PrEP is particularly useful for gay, bi+ and trans men, but also for anyone who wants to actively reduce their HIV risk.

For whom is PrEP useful?

PrEP is ideal for anyone who:

  • regularly have sex with changing partners,
  • Practising sex without a condom,
  • live in a relationship with HIV-positive partners (without detectable viral load = U=U),
  • or simply want to take out additional cover.

If you are unsure whether PrEP is right for you, talk to an AIDS service organisation or HIV specialist practice. Counselling is confidential and queer-competent.

PrEP: Application & intake

PrEP can be taken in two ways:

  • Daily: One tablet a day provides constant protection against HIV.
  • Occasion-related („on demand“): Only around sex dates - about 2 tablets 2-24 hours before sex, then 1 tablet 24 and 48 hours afterwards.

Important: The effect does not start immediately. For the right dosage and safety, you need medical advice and regular check-ups (every 3 months with HIV and kidney check).

Side effects & experiences

Most people tolerate PrEP very well. Occasionally, mild symptoms may occur in the first few weeks - e.g. headaches, nausea or stomach problems. These usually subside on their own.
Long-term side effects (e.g. on the kidneys or bones) are rare, but are monitored regularly.
Many report that PrEP makes their sex life more relaxed and anxiety-free - a gain in safety and self-determination.

PrEP: costs, prescription & purchase

  • Prescription: You can get PrEP from doctors with HIV expertise
  • Costs: The statutory health insurance funds cover the costs. Privately insured persons should clarify in advance whether their insurance will pay.
  • Purchase: Only with prescription in pharmacies - no self-procurement online!
  • Controls: HIV and STI tests as well as blood and urine tests are mandatory every 3 months.

FAQ - Frequently asked questions about PrEP

Here you will find the most important answers about effects, use, costs and side effects - explained clearly, honestly and practically.

What is PrEP and how does it work?

PrEP is a medication that protects you from HIV by preventing the virus from taking hold in your body. The active ingredients (usually tenofovir and emtricitabine) specifically block the replication of HIV. For the protection to work, you must take PrEP regularly and as prescribed. PrEP only protects against HIV, not against other STIs - for this you also need condoms

How do I get PrEP?

You can get PrEP on prescription from doctors with HIV expertise. A health check (HIV test, kidney values, hepatitis tests if necessary) is carried out before the prescription is issued. After the prescription, you can pick up the medication at any pharmacy.

Who covers the costs of PrEP?

The statutory health insurance funds cover the costs. This also includes the quarterly check-ups. If you have private insurance, the costs may be covered differently depending on your tariff - clarify this with your insurance company in advance.

What side effects can PrEP have?

Mild gastrointestinal complaints, headaches or nausea may occur in the short term, but these usually disappear after a few days. Long-term side effects are rare, but can affect the kidneys and bones. Regular blood and urine tests are therefore important. Many people do not notice anything at all - the tolerability is very well documented.

How do I take PrEP correctly?

You can take PrEP daily or take on demand.
Daily: one tablet every day, always at about the same time.
On Demand: 2 tablets 2-24 hours before sex, then 1 tablet 24 hours and 1 tablet 48 hours afterwards.

Can I get HIV even though I am taking PrEP?

If you take the tablets regularly and correctly, the risk is extremely low. Only if there are gaps in your intake lasting several days or if you take counterfeit preparations can the protection weaken. Important: PrEP only protects against HIV - not against other STIs.

What happens if I forget a PrEP dose?

If you take it daily, take the tablet as soon as you realise. If you take them on demand, precise planning is crucial to ensure that protection is built up in good time. If you are unsure whether you are still protected, seek medical advice.

Does PrEP also protect against other STIs?

No. PrEP is only effective against HIV. Condoms, safer sex practices and regular tests help against other STIs such as syphilis, gonorrhoea or chlamydia.

What is the difference between PrEP and PEP?

PrEP (pre-exposure prophylaxis): You take them as a preventative measure before a risk arises.
PEP (post-exposure prophylaxis): You take it as an emergency measure within 72 hours of possible HIV contact (the sooner the better).
Both drugs have the same active ingredient, but different applications and time frames.

Can I buy PrEP online?

No, please don't. Only medicines from pharmacies with a doctor's prescription are safe. Online offers harbour risks - from counterfeits and incorrect dosages to a lack of medical supervision.

How does the regular check-up work?

HIV tests, blood and urine tests and STI screenings are carried out every 3 months. This allows you to recognise side effects at an early stage and stay on the safe side medically.

How long can I take PrEP?

As long as you have an increased risk or feel safer with it. Some people take PrEP for years without any problems. The only important thing is to keep up with your check-ups.
