i used to take atenolol about 5 years ago. when i found out i was pregnant, she switched me to toprol. when the pharmacy switched manufacturers of the generic, my bp went up and so did my anxiety. then i was switched to bystolic name brand. well in july when i was at a new doctor, he asked me why i was taking it cause my bp was so good. i said cause when i stop, it goes up and i have a faster heartrate. it's expensive though so he switched me back to metaprolol (toprol but generic). well i don't feel as if it's working lately and wonder if generics could sometimes not work as well on some people. i read that online recently and the pharmacist told me it's not he main part of the drug but an additive or color they use in the drug that could make it less effective on some patients, etc.
i'm t hinking of starting atenolol again on monday. my resting hr has been like 85-95 the last few days and makes me anxious. anyone have any luck with this type of drug?
