Hopefully this isn't as bad as it sounds!
I am taking antibiotics for an infection, it's is an antibiotic I've had a fair few times before, usually at a lower dose. My issue is that every single time I've taken it in the past I've ended up with thrush that's needed medication to clear it up. I'm only a couple of days into the antibiotics and about to go away at the end of the week. Would I be unreasonable to tell the pharmacist I have symptoms of thrush now so that I can purchase some Canesten over the counter?
