Norvasc treats high blood pressure and angina. Available only by prescription, Norvasc does not cure either condition, but helps control them. Although many people experience no adverse reactions when taking this medication, like any drug, Norvasc has side effects.
Swelling and Flushing
Norvasc can cause swelling, most often in the hands, legs and feet. Some people on this medication experience facial swelling. Flushing---temporarily feeling too warm or even hot---can also be caused by Norvasc.
Headache
People starting Norvasc sometimes get headaches with the first few doses. Usually these headaches go away as your body adjusts to the medication. If you have continuing headaches, or if they are especially painful, let your doctor know.
Gum Problems
Norvasc belongs to a family of medications known as calcium channel blockers. Some of the calcium channel blockers can cause the gums to feel tender or to swell or bleed. Norvasc is not generally known for this side effect, but if it occurs, brush and floss regularly and see your dentist twice a year for cleanings. If problems with your gums continue despite good oral hygiene, let your doctor know.
Less Common Side Effects
A few people taking Norvasc have experienced more frequent and more painful chest pain than their typical anginal pain. An irregular heartbeat, pounding heartbeat or an elevated heart rate have also been known to occur. Other uncommon but possible side effects include feeling unusually weak or tired, stomach pain and upset stomach.
