Know the basics

What is amlodipine used for?

Amlodipine is used with or without other medications to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidneyproblems. Amlodipine belongs to a class of drugs known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily.

Amlodipine is also used to prevent certain types of chest pain (angina). It may help to increase your ability to exercise and decrease the frequency of angina attacks. Amlodipine should not be used to treat attacks of chest pain when they occur. Use other medications (such as sublingual nitroglycerin) to relieve attacks of chest pain as directed by your doctor.

How should I take amlodipine?

Take amlodipine by mouth with or without food as directed by your doctor, usually once daily.

The dosage is based on your medical condition and response to treatment. Your doctor may gradually increase your dose. Follow your doctor’s instructions carefully.

Use amlodipine regularly to get the most benefit from it. To help you remember, take it at the same time each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

If used for angina, amlodipine must be taken regularly to be effective. It should not be used to treat angina when it occurs. Use other medications (such as sublingual nitroglycerin) to relieve an angina attack as directed by your doctor. Consult your doctor or pharmacist for details.

Tell your doctor if your condition does not improve or if it worsens (for example, your blood pressure readings remain high or increase, chest pain continues or worsens).

How do I store amlodipine?

Amlodipine is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store amlodipine in the bathroom or the freezer. There may be different brands of amlodipine that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush amlodipine down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
