Tell me about PrEP


PrEP is short for pre-exposure prophylaxis. It’s a pill that is proven to help protect people from catching HIV. The same medicine has been used for many years to treat people with HIV. The treatment needs to be started before sex. Studies have looked at 2 different ways to take PrEP. Both have been shown to reduce the risk of catching HIV by at least 86%.1,2


PrEP  contains 2 drugs – tenofovir and emtricitabine. In Europe the pill’s brand name is Truvada. In other parts of the world ‘generic’ versions are available (e.g. Tenvir-EM).


The NHS doesn’t currently provide free PrEP. However, you can buy it from our special PrEP clinic at NHS list price. It is also legal to buy PrEP more cheaply online. Either way we’re here to provide advice and safety monitoring free of charge.


For more detailed information about PrEP, there’s a really helpful leaflet on the ‘i-Base’ website.
