you can take paracetamol and ibruprofen but its worth leaving time between them to see if the paracetamol works on its own. you just have to make sure you leave 4 hours between taking the same meds, so if you take paracetamol, don’t take it again for 4 hours, the same goes for ibruprofen. you can take paracetamol and then ibruprofen whenever, a hour, 2 hours 40 mins later etc, as long as you don’t take paracetamol again until its been 4 hours since you took the earlier paracetamol. did your surgeon not prescribe codeine? you’d be better taking the prescribed pain killers because its not good to take ibruprofen a lot because it causes problems.
pain killers won’t affect the antibiotics, you can take them together or separate x
