They gave me ondansetron - I am in the UK so that might be Zofran under another name. Taking regular paracetamol, cut back on codeine and just started aspirin for blood thinners, but that’s also a pain reliever so should help. I was hoping to be off most of it by now, but think the infection will delay things a little bit. You are right - it seems daft taking one drug to counteract another and when you read the data sheets it’s confusing, eg the flucloxacillin says not to take regular paracetamol with it, but I have been told to keep taking up to 8 a day. So I think it’s best to listen to your body, cut back where you can but ensure I take the antibiotics. Incidentally, not taking any last night was the best thing - I think lying down on your back straight after taking them, on an empty stomach is a big no!
