About nicardipine

High blood pressure; to prevent angina

Capsules and injection

Nicardipine belongs to a group of medicines called calcium-channel blockers. It is prescribed to treat high blood pressure (hypertension), or to prevent angina chest pain. You will have been prescribed it for one of these reasons.

It works by causing some of your blood vessels to relax and widen. This lowers your blood pressure. It also reduces the force and the rate of your heartbeat, and this helps to prevent angina chest pain. It does these things by blocking the amount of calcium that goes into the 'smooth' muscle cells in the walls of your arteries and in your heart. Calcium is needed for muscles to contract, so reducing the amount of calcium causes the muscle cells to relax.

In some countries nicardipine is available as a modified-release capsule. This means that the capsules release nicardipine more slowly than the standard capsules. They can be prescribed for people with high blood pressure.

Before taking nicardipine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking nicardipine it is important that your doctor knows:

  • If you have any heart problems (other than angina or high blood pressure), or if you have recently had a heart attack.

  • If you have angina pain when you are resting as well as when you are active.

  • If you have been told you have narrowing of the main blood vessel from your heart (aortic stenosis).

  • Si vous êtes enceinte ou si vous allaitez.

  • Si vous avez des problèmes de fonctionnement du foie ou des reins.

  • Si vous prenez ou utilisez d'autres médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

  • Si vous avez déjà eu une réaction allergique à un médicament.

  • Si vous êtes atteint d'une maladie sanguine héréditaire rare appelée porphyrie.

How to take nicardipine

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. It will give you more information about nicardipine and will provide you with a full list of the side-effects which you may experience from taking the capsules.

  • Standard nicardipine capsules (Cardene®) are taken three times a day. There are two strengths available - 20 mg and 30 mg. You will be prescribed the lower-strength capsule first, and then the higher-strength capsule after a few days if your doctor feels it is necessary.

  • Modified-release capsules are taken twice daily - morning and evening. There are three strengths available - 30 mg, 45 mg and 60 mg. You will be prescribed the lower-strength capsule to begin with and your dose adjusted later if needed.

  • Space out your doses during the day, and try to take them at the same times each day as this will help you to remember to take your doses regularly. Swallow the capsules whole with a drink of water. You can take nicardipine before or after meals.

  • Si vous oubliez de prendre une dose, prenez-la dès que vous vous en rendez compte. Si, lorsque vous vous en rendez compte, il est presque temps de prendre la dose suivante, prenez-la à l'heure prévue, mais ne prenez pas la dose oubliée. Ne prenez pas deux doses en même temps pour compenser une dose oubliée.

Tirer le meilleur parti de votre traitement

  • Essayez de vous rendre à vos rendez-vous réguliers avec votre médecin. Il pourra ainsi vérifier vos progrès.

  • Your doctor will discuss with you the possibility of unwanted side-effects. When you first start taking nicardipine you may experience headaches, feeling flushed, and some dizziness. These effects usually only last for a few days, but if they continue or become troublesome, you should let your doctor know.

  • If you drink alcohol, ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on nicardipine as it can increase the chance that you experience side-effects, such as feeling dizzy or light-headed.

  • You should not drink grapefruit juice while you are on nicardipine. This is because a chemical in grapefruit juice increases the amount of nicardipine in your blood and this makes side-effects more likely.

  • Nicardipine is a medicine which helps to prevent angina pain from developing, it will not provide you with immediate pain relief if you have an angina attack. Your doctor will give you a different medicine to take for this.

  • If you buy any medicines, always check with a pharmacist that they are suitable to take with your other medicines. Some anti-inflammatory painkillers can reduce the effectiveness of nicardipine.

  • If you need to have an operation or any medical treatment, tell the person carrying out the treatment which medicines you are taking. Nicardipine and some anaesthetics can interact and may cause your blood pressure to drop too low.

  • Treatment with nicardipine is usually long-term unless you experience an adverse effect. Continue to take the capsules unless you are told otherwise by your doctor. If it is necessary for you to stop, your doctor may want you to reduce your dose over a few days, as there is some evidence to suggest that stopping taking nicardipine suddenly can cause some symptoms to return.
