Q and A


I have taken PEP every 12 hours instead of every 24…

Hi, currently i’m on PEP. Today is my 6th day and my question is on the 1st day and today, instead of 24 hour gap I have taken PEP in a 12 hour gap. Does it effect the efficiency of PEP? I don’t have any side effects till now.


Hi, how are you doing?

No. Taking additional doses of PEP will not reduce how well it works.

This does not mean it is a good idea to continue taking PEP every 12 hours. It should be taken every 24. Is there a reason you have taken these few doses earlier?

Taking more than prescribed can risk you experiencing more side effects, or not having enough treatment to complete the full 28 day course.
