Hi,
I'd simply insist on going on another medication, providing you need one! Have you tried making lifestyle adjustments first? Losing weight? You are lucky you had no adverse effects while on Norvasc. Mine had to be discontinued shortly after I was put on it. I am on Felodipine with no serious side effects.
Is there a reason for your doctor's preference for a CCB in the treatment of your hypertension? (A certain medical condition etc.) If not, why not consider trying another medication from a different class? What type of hypertension do you have and to what degree?
