My father keeps threatening to stop taking Aricept because he gets such bad hot flushes in his face and ears. The doctors dismiss this as something they've never heard of before, but I have found some reference to it as a side effect. He's been on it for about 15 months and takes it at night. He sleeps a lot during the day and at night. Maybe we should let him stop taking it, yet his memory test scores have improved so convincingly that it seems a shame. Has anybody else had this problem. He seems to blame all his ills on the drug because he doesn't remember that he has had symptoms for a few years. Any ideas on how to minimise the flushes?
