Adalat capsules with food and drink

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.

You can take Adalat capsules either with or without food.

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.

Do not start taking Adalat capsules within 3 days of drinking grapefruit juice or eating
grapefruit. Tell your doctor if you have had grapefruit or grapefruit juice in this time.
Also, do not drink grapefruit juice or eat grapefruit whilst taking Adalat capsules.
Grapefruit juice is known to increase the blood levels of the active ingredient,
nifedipine. This effect can last for at least 3 days.

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.

Do not drink grapefruit juice or eat grapefruit while taking Adalat capsules.

your doctor for advice before taking this medicine.
