What is HIV PrEP?

PrEP is a way of preventing HIV infection by taking a pill on an ongoing basis before sex and continued after sex. It’s taken by someone who doesn’t have HIV, to prevent them from getting HIV. The PrEP pill is an antiretroviral drug – the same type of pill taken by someone who already has HIV to treat HIV. You’re protecting your own HIV negative status by taking PrEP.
PrEP stands for pre-exposure prophylaxis.

What goes into PrEP?

One drug is approved for use as PrEP – the branded drug Truvada. PrEP is also available in generic, unbranded form – these drugs are known as generics. Generics contain the same ingredients as Truvada and work in the same way. Truvada and the generics contain 2 active drugs:
  • Tenofovir TDF
  • Emtricitabine FTC.


PrEP and STIs

PrEP only protects you against HIV. You need to take other precautions to reduce your risk of contracting other sexually transmitted infections (STIs) such as gonorrhoea, chlamydia, syphilis and hepatitis C. We recommend regular STI testing. You also need to do an HIV test every three months.
