<s>[INST] My brother in law has been on opiates which were prescribed for pain following back surgery. It appears that he is having personality changes due to the mess. Could you tell me what the prescribed medication is to ease him off of dependency and still manage pain? [/INST] Hi, I have gone through the symptoms you have mentioned, you have not mentioned the duration since he is taking the medications. Anyway, opiates are prescribed for acute pain relief following surgery mainly for the first few days only, so if it is already more than a week after his surgery then no need to take these medicines. Shift him to the simple painkillers like tramadol and paracetamol. Automatically he won't feel any need for opiates </s>
