Amlodipine contains the active substance amlodipine which belongs to a group of medicines called calcium antagonists.

Amlodipine is used to treat high blood pressure (hypertension) or a certain type of chest pain called angina, a rare form of which is Prinzmetal's or variant angina.

In patients with high blood pressure this medicine works by relaxing blood vessels, so that blood passes through them more easily. In patients with angina Amlodipine works by improving blood supply to the heart muscle which then receives more oxygen and as a result chest pain is prevented. This medicine does not provide immediate relief of chest pain from angina.

  • If you are allergic (hypersensitive) to amlodipine, or any of the other ingredients of this medicine (listed in section 6), or to any other calcium antagonists. This may be itching, reddening of the skin or difficulty in breathing.
  • If you have severe low blood pressure (hypotension).
  • If you have narrowing of the aortic heart valve (aortic stenosis) or cardiogenic shock (a condition where your heart is unable to supply enough blood to the body).
  • If you suffer from heart failure after a heart attack.

Talk to your doctor or pharmacist before taking Amlodipine.

You should inform your doctor if you have or have had any of the following conditions:

  • Recent heart attack
  • Heart failure
  • Severe increase in blood pressure (Hypertensive crisis)
  • Liver disease
  • You are elderly and your dose needs to be increased

Amlodipine has not been studied in children under the age of 6 years. Amlodipine should only be used for hypertension in children and adolescents from 6 years to 17 years of age (see section 3).

For more information talk to your doctor.

Tell your doctor or pharmacist if you are taking, or have recently taken or might take any other medicines, including medicines obtained without a prescription.

Amlodipine may affect or be affected by other medicines, such as:

  • ketoconazole, itraconazole (anti-fungal medicines)
  • ritonavir, indinavir, nelfinavir (so called protease inhibitors used to treat HIV)
  • rifampicin, erythromycin, clarithromycin (antibiotics)
  • hypericum perforatum (St. John's Wort)
  • verapamil, diltiazem (heart medicines)
  • dantrolene (infusion for severe body temperature abnormalities)
  • tacrolimus, sirolimus, temsirolimus, and everolimus (medicine used to alter the way your immune system works)
  • simvastatin (a cholesterol lowering medicine)
  • cyclosporine (an immunosuppressant)

Amlodipine may lower your blood pressure even more if you are already taking other medicines to treat your high blood pressure.

Grapefruit juice and grapefruit should not be consumed by people who are taking Amlodipine. This is because grapefruit and grapefruit juice can lead to an increase in the blood levels of the active ingredient amlodipine, which can cause an unpredictable increase in the blood pressure lowering effect of Amlodipine.

The safety of amlodipine in human pregnancy has not been established. If you think you might be pregnant, or are planning to get pregnant, you must tell your doctor before you take Amlodipine.
