Does PrEP interact with anything?

PrEP generally has few interactions with medicines or supplements. We always check this for you.

Medicines
It is especially important to be careful with other medicines that can affect your kidneys, such as certain painkillers (diclofenac, ibuprofen). 

Supplements
If you take creatine as a supplement, for example for the gym, check carefully which type you are using (creatine monohydrate or creatine ethyl ester). The ethyl ester version can affect your kidney function test, making it look as though your kidneys are working less well than they actually are. This can affect whether you are able to start PrEP.

Alcohol and/or drugs
Alcohol and drugs do not affect how PrEP works. There is, of course, still the risk that you forget to take your PrEP.
