PrEP (pre-exposure prophylaxis) can prevent HIV. It is for people who are HIV negative, and at risk of getting HIV. PrEP is 2 medicines, tenofovir and emtricitabine, in a single tablet. There are two ways of taking it.
Anyone can use this but it is ideal if you have frequent sex, or if you have infrequent sex but prefer not to plan or delay sexual activity.
Daily PrEP involves taking 1 tablet every day, at about the same time each day. Have a regular routine for taking your tablet, eg, in the morning after you brush your teeth. It is important to take your PrEP tablet every day.
This is also known as event-driven PrEP or on-demand PrEP. It involves planning and using reminders every time you have sex, with specific dosing before and after sex. It is extremely important that you don't miss doses. This option is currently only shown to be effective for cisgender gay and bisexual men and may be an option if you have infrequent sex (less than twice a week) and if it is easy for you to plan or delay sexual activity.
