If I have high blood pressure should I take suphedrine I take 40mg of prinivil (lisinopril) and want to know if it's ok to take 2 30mg of suphedrine

If. If your BP is well controlled on the prinivil, (lisinopril) taking sudafed for a few days should not cause much difficulty.
NO. If "suphedrine" is pseudoephedrine, it is a cardiac stimulant and should be avoided, particularly in patients with HBP.
