1. What is Norvasc and what is it used for

Norvasc contains the active substance amlodipine, which belongs to a group of medicines called
calcium antagonists.
Norvasc is indicated for the treatment of high blood pressure (hypertension) or chest pain, known as
angina pectoris, and its rare form known as Prinzmetal's angina (vasospastic angina).
In patients with high blood pressure, this medicine widens the blood vessels so that blood can flow more
easily. In patients with coronary heart disease, Norvasc facilitates blood flow to the heart muscle, increasing
the amount of oxygen supplied, which in turn prevents chest pain. This medicine does not provide immediate
relief from chest pain caused by angina.

2. Important information before taking Norvasc

When not to take Norvasc

• if the patient has been diagnosed with an allergy (hypersensitivity) to amlodipine or any of the other ingredients of this medicine listed in section 6, or to any other calcium antagonist. Symptoms may include itching, skin redness, or difficulty breathing,
• if the patient has very low blood pressure (hypotension),
• if the patient has a narrowing of the aortic valve (aortic stenosis) or cardiogenic shock (a condition in which the heart cannot supply enough blood to the body),
• if the patient has heart failure after a heart attack.

Warnings and precautions
