Hello. If I’m taking prep on demand (2-1-1) and I take the followup doses (third and forth pill) hours early. should I extend and take another pill (2-1-1-1).
Ie
Day 1 – 6pm – 2 pills
Day 2 – 10am – 1 pill
Day 3 – 10am – 1 pill
Day 4 – Extra dose ?
Answer
Hi there
2:1:1 dosing for PrEP also involved knowing when you had sex and you didn’t include this info.
Please see this guide for more details about this:

You can always take PrEP for an additional day, though it isn’t needed – ie 2:1:1:1
