Nifedipine 30mg tablet
What Nifedipine is used for:
It is used to treat high blood pressure or angina.
For high blood pressure: it works by relaxing and expanding the blood vessels. This makes the blood flow more easily and lowers blood pressure. Lower blood pressure reduces the strain on your heart.
For angina: it works by relaxing and expanding the arteries supplying the heart. This allows more blood and oxygen to reach the heart and decreases the strain on it. Your angina attacks will be less severe and less frequent if there is less strain on the heart.
Do not take Nifedipine:
If you have had a heart attack within the last month.
If you get a sudden angina attack.
If you have unstable angina.
If you are allergic to nifedipine, any other similar medicines (known as dihydropyridines) or any of the other ingredients of this medicine.
If you are taking rifampicin, an antibiotic.
If you have a liver disease that prevents your liver from working properly.
If you have inflammation of the bowel or intestines, such as Crohn’s disease.
If you have an obstruction or narrowing in your intestines, or have had this in the past.
If you have ever had an obstruction in the gullet (the oesophagus - the tube connecting the throat to the stomach).
If you have been told that you have a narrowing of the aortic heart valve (stenosis).
If you 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.
If you have a “Kock pouch” (a surgically constructed intestinal reservoir with an opening through the abdominal wall) in your gut.
If your blood pressure continues to rise despite treatment.
