PrEP (pre-exposure prophylaxis, meaning prevention before exposure) is a medication that HIV-negative people use to prevent HIV infection. Taken as prescribed, it lowers the risk of getting HIV through sex by about 99%. [1]
In Hungary few people know about it yet, and few places offer it. At the Sabjanics Medical Center clinic, our specialist explains your options in detail, does the tests you need, and follows you up regularly for the whole time you are on PrEP.
Who is PrEP recommended for?
PrEP is recommended for HIV-negative adults and adolescents who have an ongoing risk of HIV infection, for example: [3]
- who do not always use a condom with a casual or new partner,
- whose HIV-positive partner is not yet receiving effective treatment,
- in whom another sexually transmitted infection has been confirmed in the recent period,
- who have repeatedly needed PEP treatment. [4]
How is PrEP taken?
PrEP is most often a tablet taken every day. Maximum protection develops after about 7 days of regular use for anal sex, and about 21 days for vaginal sex. [3]
For anal sex – where suitable – event-based (“2-1-1”) dosing is also an option: 2 tablets 2–24 hours before sex, then 1 tablet each 24 and 48 hours later. This dosing cannot be used if you have hepatitis B infection. [2]
Our specialist will discuss with you at the consultation which method is right for you. [3]

- While taking PrEP, HIV and STI screening is usually recommended every three months, and kidney function also needs to be checked regularly. [2]
- How should I prepare?

What should you keep in mind while on PrEP?
PrEP only protects against HIV: it gives no protection against other sexually transmitted infections or unplanned pregnancy, so condoms are still important. [3]
Protection depends on taking it accurately and regularly: missed doses make it less effective. [2]
Protect yourself with confidence! If you feel PrEP could help you too, book an appointment at our clinic – discreetly, without judgement.
