PrEP for trans and non-binary people

PrEP is just as safe and effective for people who are transgender or non-binary as it is for cisgender people.

Dosing choices depend on the type of sex, although daily dosing has generally been recommended. 

Everyone can now start PrEP with a double dose (two pills). This works in two hours rather than the old advice to take daily PrEP for 7 days before sex.

After sex, take daily PrEP (one pill) for seven days if you want to use event-based dosing (called 2:7). If you want to continue on daily PrEP, it is important to take at least 4 daily doses each week.

Anyone having insertive or receptive anal sex or insertive vaginal/frontal sex can use 2:1:1 event-based dosing. Event-based dosing using 2:7 dosing is recommended for receptive vaginal/frontal sex.

PrEP is very safe with hormone treatment

Even though you might worry about drug interactions, neither your hormone or PrEP levels will be affected.

Liverpool University produces an excellent guide to drug interactions between hormone treatments and other HIV meds:

Ongoing studies are looking at other aspects of PrEP in trans women and men.
