What should I know about nifedipine before taking it?

Before taking nifedipine, you should know that:

  • This medication can cause drowsiness and lightheadedness. (Do not drive or perform other strenuous tasks until you know how you react to the drug.)
  • Your doctor should be informed if you have had any digestive system problems; heart, liver or kidney disease; or a recent myocardial infarction.
  • You should also tell your doctor if you have surgery scheduled (including dental surgery), or if you are pregnant or planning to become pregnant.
  • Nifedipine interacts with certain medications; tell your doctor about any medicines you are currently taking or any medication allergies you have.
  • You should not eat grapefruit or drink grapefruit juice while using nifedipine.
  • Excellent dental and gum care -- including regular brushing, flossing, and dental visits -- are important while taking nifedipine.
