I’m due to have a colonoscopy & have to stop any codeine a week before. I take Solpadeine Max (paracetamol with codeine) & some form of ibuprofen & codeine daily. Have done for many months. I read that you shouldn’t go “cold turkey” although I reckon that’s with pure codeine phosphate. Certainly don’t want to suffer any nasty withdrawal symptoms. What’s the best thing to do? My procedure is in 2 weeks.
