Question
Can I take an ant-acid before PrEP?
16 July 2023. Related: All topics, Drug interactions.
Hi,
I have been taking PrEP for 10 days but I have read on this website that I should have not taken ant-acid with PrEP. I am not worried as I have taken anti acid 2-3 hours before PrEP as I had side effects of indigestion. Will this effect my protection level as I had unprotected sex with some one of whom I don’t know HIV status.
Thanks in advance
Regards
Ajay
Answer
Hi, how are you doing?
No. This will not reduce how effective PrEP is.
There is a risk of interaction between PrEP and ant-acids but this is avoided by taking the ant-acid more than 2 hours before PrEP (or 6 hours after) which you have done.
