My husband, age 65, has some chronic health issues (3 back surgeries including fusion, extensive DDD, DJD, chronic pain, history o heart attack and stent placement, history of stroke, diabetes, peripheral neuropathy, etc.). He has had afib since last year. This May he had an episode and was hospitalized, had cardioversion (which didn't work), and was started on Amiodarone. He continues to have extreme problems with dizziness, light headedness, headaches. The dizziness and near fainting episodes just do not seem to be improving. Is this to be expected? I have heard that Amiodarone is a tough drug to deal with for some patients. For whatever reason, the cardiologist seems hesitant to change to a different drug. But this is really getting to my husband and is really affecting his quality of life. Despite getting up very slowly, he is having a terrible time with this. Also can't stand the heat and gets very exhausted with a minimum of activity? Any suggestions? Thanks so much for your help.
