PrEP is only effective, when taken both before and after sex. There are two ways you can take PrEP, depending on your circumstances and how often you have sex:

  1. Daily dosing – continuous use of PrEP every day.
  2. On-demand dosing or event-based dosing – see our FAQ about on-demand or event-based doing for more information.
