Beta blockers are counter effective in my case, when I stand my BP drops for a few seconds and then recovers, my heart is presumably what is keeping the blood pressure normal.

Florinef increases BP, but it increases the blood volume, which means more blood in the total circulation, an increased pressure which will prevent the drop and symptoms.

Light headedness is my main symptom. A BP in the arm doesnt reflect a true BP in the brain, or other vascular beds. Just wish I knew the answers to this.
