What is the most important information I should know about nifedipine?

You should not use nifedipine if you are allergic to it.

Before taking nifedipine, tell your doctor if you have kidney or liver disease (especially cirrhosis), coronary artery disease, congestive heart failure, or digestive problems.

If you need surgery, tell the surgeon ahead of time that you are using nifedipine. You may need to stop using the medicine for a short time.

Many drugs can interact with nifedipine. Tell your doctor about all other medications you use.

Do not stop taking nifedipine without first talking to your doctor, even if you feel fine. Stopping suddenly may make your condition worse. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
