FOR

Adalat Retard contains nifedipine, which belongs to a group of medicines called calcium antagonists.

Adalat® Retard is used to treat high blood pressure or angina (chest pain).

For high blood pressure: Adalat® Retard 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: Adalat® Retard 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 Adalat® Retard:

   If you have had a heart attack within the last month.

   If you get a sudden angina attack. Adalat® Retard will not help relieve symptoms of angina quickly.

   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 (listed in section 6).

   If you are taking rifampicin, an antibiotic.

   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 your blood pressure continues to rise despite treatment (malignant hypertension).

•    If you have been told to avoid lactose, that you have a hereditary condition called Lapp lactase deficiency or glucose-galactose malabsorption.
