Adalat LA contains nifedipine, which belongs to a group of medicines
called calcium antagonists.
Adalat LA is used to treat high blood pressure or angina (chest
For high blood pressure: Adalat LA 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
For angina: Adalat LA 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 LA:
 If you have had a heart attack within the last month.
 If you get a sudden angina attack. Adalat LA will not help relieve

symptoms of angina quickly.
 If you have unstable angina.
 If you are allergic to the active ingredient (nifedipine), to any other

similar medicines (known as dihydropyridines) or to any of the other
ingredients. The ingredients of Adalat LA are listed in section 6.

If you have been told that you have a narrowing of the aortic
heart valve (stenosis).

(cardiogenic shock), during which you became breathless, pale and
had a cold sweat and dry mouth.

reservoir with an opening through the abdominal wall) in your gut.

(malignant hypertension).
Tell your doctor and do not take Adalat LA if any of

Talk to your doctor before you take Adalat LA if any of
these apply to you.
