Can I switch between daily and event-based dosing?
If you are able to use on-demand dosing, PrEP is very adaptable if your circumstances change.
If your HIV risk changes, you can stop and restart PrEP, or change the way in which you take it. PrEP can be individualised to your needs at different times.
Talk through ways of taking PrEP at your clinic and about how to stop or restart when you need to.
On-demand dosing is NOT an option:
- If you have hepatitis B.
- For women who want protection during receptive vaginal sex, as a seven day lead-in is needed.
- For trans women and trans men and non binary people who want protection from receptive vaginal or front hole sex.
