I Don't really know much about this drug, the Dr said he has had good results with it for pots patients with high blood pressure at times. It's not supposed to raise the blood presure like some of the other medications the ones he mentioned were proamatine and fluronef I've had 3 injections so far without any dramatic difference in symptoms but he started me on a low dose and plans to increase it so I figured I would try It a few more times to give it a fair chance.
