Hi everyone -I was wondering if anyone has had to switch their medicine from atenolol to metoprolol er succinate -I take 25mg in the am and half a pill in pm. I did really well with the atenolol but it’s only been two days with metoprolol but I don’t feel well -I feel nervous and quezy early and then as the day goes on I start to feel better but was wondering if this is normal and does it just take awhile for your body to adjust to the new medicine -I did not know there was a shortage until I picked up my prescription and the pharmacist told me and she said I would not notice a difference -my EP never called to tell me I had been switched. Also wondered if everyone on metroprolol succinate were getting good results. I know have to give it a chance but wondered what results others were having -I like that old saying if it ain’t broke don’t fix it but guess it does not apply to medicine!!!!!
