Sandra said: "Continue to take Amlodipine and talk to your doctor if you experience serious side effects, stop taking Norvasc, as a slow reduction in the dose may be needed. Amlodipine controls high blood pressure or angina. Norvasc blocks the transport of calcium into the smooth muscle cells lining the coronary arteries and other arteries of the body. The two most common side effects of Amlodipine are generally mild and reversible."
