Hi, just wondering if anyone has been subscribed Nefopam for pain relief and had a very bad reaction like my dad. His memory was deteriorating but he’s got so bad in the last few days after only a week in this drug. I have stopped him taking it and reported it to the doctors after he was on walk about all night due to being high as I kite on these meds and not knowing where he was or who anyone was and then having a bad fall in the dark. He appeared a lot better this morning but has deteriorated again this evening ?x I was wondering if anyone new if this will wear off as the Nefopam gets out of his system? Or has it caused permanent damage ?
