Dear Friend thanks for writing to healthcare-magic BUSPAR or buspiron is an anxiety lowering drug and as such is not a drug meant to lower your blood pressure primarily. if you are not feeling well with lisinopril, please discuss it with your physician and tell him what you find wrong with it. some effects may go with time too. but do not increase dose of buspiron on your own. moreover even if you could not tolerate lisinopril , there many more proper BP lowering drugs which can be tried rather than using buspiron. so discuss it out and take an appropriate medication. i wonder if buspiron is OTC drug in your country! sincerely
