Thought I'd try this question once more. Is anyone taking Proamatine to control low blood pressure? My father-in-law has Parkinson's, and is having trouble with orthostatic hypotension--low blood pressure upon standing. The Proamatine is supposed to raise his blood pressure, but so far, is not doing the trick. He's actually passed out a few times. I'd appreciate any experiences, advice, information, research--anything about Proamatine. So far, my father-in-law is seeing a neurologist but not one who specializes in Parkinson's. We're wondering how important it might be to get him to a specialist. Thanks to all of you, Jackie naiditch
