The active ingredient in your tablets is nifedipine, which belongs to a group of medicines called calcium channel blockers. These work by relaxing blood vessels, so that blood passes through them more easily.

Neozipine XL is used to treat high blood pressure (hypertension) or angina (a painful condition where there is a lack of blood and oxygen to the heart).

If you have angina, you may get chest pains when your heart cannot get enough blood. This usually happens during exercise or stress. Nifedipine helps to prevent this by increasing the blood supply to the heart. The tablets do not work immediately to stop the chest pain from angina.


Do not take Neozipine XL if you:

  • are allergic (hypersensitive) to nifedipine, other calcium channel blockers, or any of the other ingredients in the tablets (these are listed in section 6, Contents of the pack and other information)
  • have had a heart attack (myocardial infarction) within the last 4 weeks
  • have a sudden angina attack, Neozipine XL will not help to relieve these symptoms quickly.
  • have unstable angina.
  • have blood pressure that continues to rise even though you are being treated (malignant hypertension)
  • have been told that you have a narrowing of the aortic heart valve (stenosis).
  • have ever had a collapse caused by a heart problem (cardiogenic shock), during which you became breathless, pale and had a cold sweat and dry mouth.
  • have liver disease that prevents your liver from working properly
  • have ever had an obstruction in your intestine and gullet (tube connecting your throat to your stomach)
  • have a ‘Kock pouch’ (a surgically constructed intestinal reservoir with an opening through the abdominal wall) in your gut
  • have inflammation of the bowel or intestines, such as Crohn’s disease
  • are taking the antibiotic rifampicin (used to treat some bacterial infections)

  • have a heart condition where your heart cannot cope with increased strain (poor cardiac reserve)
  • are pregnant or intend to get pregnant
  • are breastfeeding, you should stop breastfeeding before you start taking this medication
  • have diabetes – the treatment for your diabetes may need to be adjusted
