I have had symptoms for almost 2 years now, with a diagnosis of OH, slightly controlled by salt and water intake increase. Everything got really bad about 3 months ago and I began fainting around 30 times per day. I got in with a new cardiologist and she gave me a dx of pots and started me on florinef - 0.1mg 3x per day. Even after the very first pill, I reacted horribly to it and was violently ill. I stayed on it for a week hoping that I would adjust. I decided it just wasn't worth it. She took me off of florinef and started me on 2.5 mg of midodrine once per day. A week later I saw no changes. My doctor said she wanted me on it for awhile longer to see what happens. I waited another 2 weeks and called back. She brought me back in, tested my BP and HR and as suspected, there were very little changes in BP. Yesterday, she doubled my dose of midodrine to 5mg 1x per day and added atenolol - 25mg 1x per day. I took the atenolol that morning, but didn't take my increased midodrine since I had just taken my previous dose. Within an hour of the atenolol I was having severe asthma attacks. I got the attacks under control, but remained wheezy for about 5 hours. I tried again today, but with the increased dose of midodrine. Same results. The atenolol was really messing with my asthma and I was incredibly fatigued. I pretty much couldn't stay conscious unless I was on the couch. I called my doctor and she again said that she wanted me to stay on the treatment plan for at least another week to see if I adjust to it. Has anyone else had so much bad luck with these meds? I always heard of midodrine being so good, but I can't even tell when I take it - other than intense headaches. It also makes my heart race when I'm at rest. For the few hrs that midodrine is in my system, my HR will not go below 115. Doctor says that's coincidence. I refuse to do SSRIs. I had a bad experience with Paxil that left me with chronic side effect problems. Finally, I tried to talk to my doc about getting a wheelchair/walker to use when I go to work or out an about. I currently can't drive and my work has me doing at home work until I've gone at least 3 weeks without a faint. I simply got a "you don't need that" from her and no further discussion. What do you guys think about it? I really want to get back to work!
