1. WHAT AMLODIPINE TABLETS ARE AND WHAT ARE THEY USED FOR?

Amlodipine belongs to a group of medicines known as calcium-channel blockers (calcium antagonists).

Calcium-channel blockers lower blood pressure by relaxing the blood vessel walls. They also have an effect on the heart, so that they can be used for angina (angina pectoris).

Amlodipine is used for:

  • High blood pressure
  • Various types of angina except for unstable angina

Amlodipine may be used to treat angina on its own or together with other medicines.

2. BEFORE YOU TAKE AMLODIPINE TABLETS

Do not take Amlodipine Tablets

  • If you are allergic to amlodipine or similar calcium-channel blockers (the so-called dihydropyridine derivatives), or to any of the other ingredients.
  • If you have very low blood pressure.
  • If you are suffering from shock (a very severe lowering of blood pressure by which you become unconscious).
  • If you have heart failure in the first 28 days after an acute heart attack.
  • If the blood flow from the left side of your heart is obstructed.
  • If you suffer from unstable angina pectoris.

If you are not sure whether any of the above applies to you, ask your pharmacist or your doctor.

Take special care with Amlodipine Tablets

  • If you have heart failure.
  • If you have liver problems; amlodipine must be used very carefully because the required dosage is not known exactly in this situation.

If you are under 18 years of age; amlodipine should not be given to children because there is not enough experience with its use in children.

Using other medicines

Tell your doctor or pharmacist if you are taking other medicines or if you have recently taken other medicines. This includes medicines that you can buy without a prescription.

  • Diltiazem (a medicine to treat high blood pressure and problems with heartbeat rhythm): diltiazem slows the breakdown of amlodipine in the liver and this can lead to a stronger effect of amlodipine. Other medicines that slow the breakdown of amlodipine in the liver even more, such as ketoconazole, itraconazole (medicines for fungal infections) and ritonavir (a medicine for HIV/AIDS), can lead to an even stronger effect of amlodipine.
  • The effect of amlodipine may be reduced by medicines that increase the breakdown of amlodipine, such as rifampicin (used for certain infections) and St. John’s Wort (a product for depression that can be bought without a prescription).
  • Grapefruit juice, cimetidine, aluminium/magnesium (medicines for indigestion) or sildenafil (a medicine for impotence) do not change the effect of amlodipine.
  • Amlodipine may increase the effect of other medicines used to lower blood pressure (such as beta-blockers, ACE inhibitors, alpha-blockers and water tablets). In patients at risk (for example, people who have recently had a heart attack), the combination of a calcium antagonist with a beta-blocker can cause heart failure, low blood pressure, and a (new) heart attack.
  • Amlodipine does not change the effect of atorvastatin, digoxin, warfarin or ciclosporin.

Taking Amlodipine Tablets with food and drink

Amlodipine can be taken with or without food.

Pregnancy

There is very little information on whether it is harmful to take amlodipine during pregnancy. Amlodipine should only be used during pregnancy if your doctor decides that it is absolutely necessary. Ask your doctor or pharmacist for advice before taking any medicine.

Breast-feeding

There is no information on the use of amlodipine while breast-feeding. You are advised not to breastfeed when using amlodipine. Ask your doctor or pharmacist for advice before taking any medicine.

Children

If you are under 18 years of age; amlodipine should not be given to children because there is not enough experience with its use in children.

Driving and using machines

Amlodipine may cause dizziness, tiredness, or make you feel sick. If you have any of these side effects, you should keep in mind that this can affect your ability to drive and/or use machinery.

3. HOW TO TAKE AMLODIPINE TABLETS

Always take amlodipine exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. The dose is decided by your doctor;

Take the tablets by mouth with plenty of liquid, for example a glass of water. The tablets may be taken before, during or after a meal.

Adults

Starting dose for high blood pressure and angina: 5 mg once a day.

Maximum dose for high blood pressure and angina: if there has been insufficient effect after 2-4 weeks, the dose may be increased to a maximum of 10 mg once a day.

Children

Amlodipine should not be used in children.

Elderly

There is no special dosage for the elderly; however, care must be taken when the dose is increased.

If you have kidney problems

If you have kidney problems, the dose does not need to be changed. Amlodipine cannot be removed from the blood by dialysis (artificial kidney).

If you go for kidney dialysis, amlodipine should be taken with particular caution.

If you have liver problems

The exact dose needed for patients with liver problems has not been determined. If you have liver problems, amlodipine should be used very carefully (see also the section Take special care with Amlodipine Tablets).

If you think that Amlodipine Tablets do not work or have a too potent effect, discuss this with your doctor or pharmacist.

If you take more Amlodipine Tablets than you should

If you or someone else has taken too much amlodipine, contact your doctor or pharmacist immediately.

The person concerned should be made to lie down with their arms and legs up (resting on a couple of cushions, for example). Symptoms of an overdose are: extreme dizziness and/or feeling very light-headed, problems with breathing, having to urinate very often.

If you forget to take Amlodipine Tablets:

If you have forgotten to take a tablet, you can still take it up to 12 hours after you usually take your tablet. If it is more than 12 hours after the time that you should have taken the tablet, you should not take the missed dose and you should take the next tablet at the usual time. Never take a double dose of Amlodipine Tablets to make up for the dose that you have missed.

If you stop taking Amlodipine Tablets

Your doctor has told you for how long you should take amlodipine. If you stop the treatment suddenly, your symptoms may come back. Do not stop the treatment earlier than agreed without discussing this with your doctor or pharmacist. If you have further questions on the use of this product, ask your doctor or pharmacist.
