Report UAB autonomic testing results. in Dysautonomia Discussion Posted September 17 On 9/15/2021 at 11:13 AM, cmep37 said: What sort of tests did you have? I had a full complement of autonomic testing except for sweating as they didn’t have that equipment. I don’t have POTS but rather neurally mediated hypotension. @Rexieposted the relevant information. I don’t have any symptoms of ADHD so it was prescribed off-label my my autonomic specialist. I took a low dose (took me about a month to titrate up to the lowest dose as it can give a lot of side-effects if you jump right in.) I had no problem with lying down as for me the half life was short and I took it twice a day. Half an hour after a dose I could be upright and walk normally but I doubt if it would work for the majority of POTS patients as it increases norepinephrine in the synapses.
