There’s only one drug for PrEP: Emtricitabine/Tenofovir disoproxil. It’s available as a branded tablet called Truvada, or a generic tablet. There are different ways of taking it through, such as ‘Daily use’, ‘On-demand’ or ‘7-7-7’. How you take it depends on how often you’re having sex, and if you’re having vaginal or anal sex.
