I have some left over that I had for awful period pain/ adenomyosis, that are now out of date. I'm going to the dentist today and suspect will need root canal - they are very reluctant to prescribe codeine where I now live (and not available otc, at any strength) but it really helped manage the pain from the first root canal I had a few years ago, for the 36 hours.
Will the expired cocodamol still work?
