Norvasc is used for treating high blood pressure and angina (chest pain). It may be used alone or with other medicines. Norvasc is a calcium channel blocker. It works by relaxing (dilating) your blood vessels, lowering blood pressure, and decreasing heart rate, which lowers the workload on the heart. It also dilates coronary arteries increasing blood flow to the heart.
Use Norvasc as directed by your doctor.
- Take Norvasc by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
- Continue to use Norvasc even if you feel well. Do not miss any dose.
- If you miss a dose of Norvasc, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Norvasc.
