What is amlodipine?

Amlodipine is used to treat high blood pressure (hypertension) and to prevent angina (chest pain). It may help to increase your ability to exercise and decrease how often you get chest pain. It works by relaxing your blood vessels so blood can flow more easily, and in this way lowers your blood pressure. Amlodipine belongs to a group of medicines called calcium channel blockers. In New Zealand amlodipine is available in different strengths of tablets (2.5 mg, 5 mg and 10 mg).

Dose

The usual dose of amlodipine is 5 milligrams once daily. Some people may need a higher dose of 10 milligrams once daily.
Always take your amlodipine exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much amlodipine to take, how often to take it, and any special instructions.

How to take amlodipine

Timing: Take amlodipine once a day. Try to take your doses at the same time each day. You can take amlodipine with or without food. Swallow your tablet with a glass of water.
Limit or avoid drinking alcohol while you are taking amlodipine. It may increase your chance of side effects such as feeling dizzy.
Missed dose: If you forget your dose, take it as soon as you remember that day. But, if it is nearly time for your next dose, just take the next dose at the right time. Do not take double the dose.
Keep taking amlodipine regularly. Treatment with amlodipine is usually long term. Do not stop taking amlodipine suddenly; speak to your doctor or nurse before stopping.
