Hello everyone My husband has been diagnosed with early Alzheimer's dementia after having brain scans He was immediately put on donepezil medication but it really made him feel sick and his heart rate kept going down which was causing dizziness he started off at 68 then went down to 57 then it went to 53 so at this point he has been changed to rivastigmine patches at least now he has no sickness bouts but still going dizzy on top of this he has a nasty chest infection yesterday the dr checked his pulse and it had gone back up to 56 hooray i said but dr says it is because of his chest infection that it is a little up so have to go and have him checked after a course of antibiotics Has anyone else experienced this please I am worried he will fall over Also I believe that these patches are not as effective as the tablets He has been very nasty tempered for about a week now but i just have to wait and see how he is after this nasty infection clears up as he is on a low dosage 4.6 mg patch and they cannot put it higher until they sort his heart rate out thankyou so much for reading my post
