He went to the doctor 2 weeks ago complaining of more pain than usual and was prescribed augmentin, he is already taking oramorph and diazepam and citalopram, he is experiencing ?severre tiredness, headaches, itching and stomach irritation since he started taking them, should he stop taking them? and why these tablets for back pain?
