I went to the Doctor and told him I have been on Beta Blocker nebivolol for 15 years. He pointed out that one of the side effects of nebivolol was that it caused diabeties. Well he then prescribed 10mg of Lisinopril and told me to replace my beta Blocker with this. I said ok and took my 10 mg pill and was ok for about 5 hours. Then my chest felt like a mack truck was on it and the pain lasted for 8 hours. I had such pain before with my Beta Blocker but that was because I took too much at times of high stress. But that pain only lasted 1 hour. This Lisinopril pain lasted 8 hours and I was jumping in bed like a mexican jelly bean. The next morning I called my doctor and told him what happened and he said "that is not a side effect of the drug and just keep taking it." . I told him the dose was too high for me and can I cut it in half. He told me just take it and don't give both of us a heart attach. Well I dumped my doctor after such advice and am looking for a new one. I tried taking 2.5 mg and got similar pains though reduced. Finally I went back to my old drug and feel much better though I am not happy that my old drug causes diabetics. No body ever told me that. I am more stressed out now then I was before and hope I can find a doctor, who has a good bedside manner and knows what the hell he is talking about. Thank God for this site.
