Can i have two glasses of orange juice while i am taking 8 mg perindopril ace inhibitor and 10 mg of bisoprolol beta blocker daily for hypertension.

Not the best idea: While there are no specific precautions about drinking orange juice with these medications, you may be referring to the fact that sometimes orange juice contains potassium supplementation. You are correct that one should be very cautious with extra potassium while taking an ACE inhibitor. Beyond that, two glasses of orange juice contains 220 calories of simple carbohydrate: not a healthy choice.
