1. What Adalat capsules are
Adalat capsules contain nifedipine, which belongs to a group of medicines called calcium
antagonists.
Adalat capsules are used to treat high blood pressure, angina (chest pain) or a condition
called Raynaud’s phenomenon which causes discolouration (often whitening) of the fingers and
toes.
For high blood pressure: Adalat capsules work 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 capsules work 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.
Adalat capsules can increase the risk of serious heart problems in patients with high blood
pressure or angina. Because of this, Adalat capsules are only used in these patients if no other
treatments are appropriate.
For Raynaud’s phenomenon: Adalat capsules work by relaxing and expanding the blood vessels
in the fingers and toes. This helps ensure a good blood supply.

2. Before you take Adalat capsules
Do not take Adalat capsules:
• If you have had a heart attack within the last month.
• If you get a sudden angina attack. Adalat capsules 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 capsules are
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).
�Tell your doctor and do not take Adalat capsules if any of these apply to you.

Your doctor will take special care:
• If you have low blood pressure. Your blood pressure may be decreased further by this
treatment.
• If you have a heart condition where your heart cannot cope with increased strain (poor
cardiac reserve).
• If you are pregnant.
• If you are breastfeeding.
• If you are a diabetic. The treatment for your diabetes may need to be adjusted. If you have
any questions about this, ask your doctor.
• If you are on kidney dialysis. If you have a very high blood pressure and a low blood volume,
you might experience a sudden drop in blood pressure when you take Adalat capsules.
• If your liver is not working properly. Your doctor may need to do some blood tests. You may
also be given a lower dose of Adalat capsules.

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

Tell your doctor:
• If your chest pain (angina) gets worse (comes on more often or more severely) over a matter
of hours or days. You may be advised not to take Adalat capsules.
• If you have chest pains after taking your first dose of Adalat capsules. Your doctor may
wish to change your treatment.
• If you notice increased breathlessness.
• If you notice swelling of the ankles.
�Tell your doctor before you take the next dose if any of these apply to you.

Also tell your doctor:
• If you are giving a urine sample. Adalat capsules may interfere with the results of certain
urine tests.
• If you are a man who has been unable to father a child by in vitro fertilisation. Drugs like
Adalat capsules have been shown to impair sperm function.

problems.

Use in children: Adalat capsules are not recommended for use in children and adolescents
below 18 years of age, because there are only limited data on the safety and efficacy in this
population.
If you take too many capsules
� Get medical help immediately. If possible, take your capsules or the box with you to show
the doctor.
Taking too many capsules may cause your blood pressure to become too low and your heartbeats
to speed up or slow down. It may also lead to an increase in your blood sugar level or an increase
in the acidity of your blood, swelling in the lungs, low blood oxygen levels and disturbances in
consciousness, possibly leading to unconsciousness.
If you forget to take the capsules
Take your normal dose immediately and continue taking your capsules as prescribed, waiting 8
hours before taking your next dose.
Do not take a double dose to make up for the missed dose.

swelling of the larynx that may result in a life-threatening outcome)
• fast heart beat (tachycardia)
