Amlodipine Is a Calcium Channel Blocker Used to Treat High Blood Pressure and Chest Pain

Amlodipine is a prescription medication that belongs to a class of drugs called calcium channel blockers (specifically, the dihydropyridine type). It's one of the most commonly prescribed medications in the United States, used by millions of people every day to manage high blood pressure and angina (chest pain related to heart disease).

If you've just been prescribed Amlodipine — or you're researching it for someone you care about — this guide covers everything you need to know in plain language.

What Is Amlodipine?

Amlodipine was first approved by the FDA and originally sold under the brand name Norvasc. The patent expired in 2007, and today it's available as an affordable generic from multiple manufacturers.

Here are the basics:

• Generic name: Amlodipine (also called Amlodipine Besylate)
• Brand names: Norvasc, Katerzia (oral suspension), Norliqva (oral solution), Sdamlo
• Drug class: Calcium channel blocker (dihydropyridine)
• Controlled substance: No — Amlodipine is not a controlled substance
• Available forms: Oral tablets (2.5 mg, 5 mg, 10 mg), oral suspension (1 mg/mL), oral solution, powder for oral solution

What Is Amlodipine Used For?

Amlodipine is FDA-approved to treat several conditions:

High Blood Pressure (Hypertension)

This is the most common reason Amlodipine is prescribed. It helps relax blood vessels so blood flows more easily, which lowers blood pressure. It's approved for adults and children 6 years and older.

Chronic Stable Angina

Angina is chest pain caused by reduced blood flow to the heart. Amlodipine increases blood and oxygen supply to the heart muscle, reducing the frequency and severity of angina episodes.

Vasospastic (Prinzmetal's) Angina

This is a type of angina caused by spasms in the coronary arteries. Amlodipine relaxes these arteries and prevents spasms.

Coronary Artery Disease

Amlodipine can reduce the risk of hospitalization for angina and the need for coronary revascularization procedures in patients with coronary artery disease.

Off-Label Uses

Some doctors prescribe Amlodipine off-label for Raynaud's phenomenon (a condition causing reduced blood flow to fingers and toes) and migraine prevention.

How Is Amlodipine Taken?

Amlodipine is designed to be simple to take:

• Frequency: Once daily
• With food: Can be taken with or without food
• Timing: Take it at the same time each day for best results
• Tablets: Swallow whole
• Liquid forms: Shake the oral suspension before use

Typical Doses

• Adults (hypertension): Start at 5 mg once daily; may increase to 10 mg once daily. Maximum dose is 10 mg/day.
• Adults (angina): 5 to 10 mg once daily
• Older adults: Start at 2.5 mg once daily due to slower metabolism
• Children (6-17 years): 2.5 to 5 mg once daily
• Liver impairment: Start at 2.5 mg once daily and increase slowly

Important: Never change your dose or stop taking Amlodipine without talking to your doctor first. Stopping suddenly can cause a dangerous spike in blood pressure.

Who Should Not Take Amlodipine?

Amlodipine is not appropriate for everyone. You should not take it if you have:

• An allergy to Amlodipine or any of its ingredients
• Cardiogenic shock — a serious condition where the heart can't pump enough blood
• Severe aortic stenosis — severe narrowing of the aortic valve
• Severe hypotension — already very low blood pressure

Use with caution if you have:

• Liver disease: Your doctor will start with a lower dose and monitor you closely
• Heart failure: Amlodipine should be used carefully in patients with heart failure

Tell your doctor about all medications you take, including over-the-counter drugs and supplements. Amlodipine has some important drug interactions to be aware of.

What Are the Side Effects?

Most people tolerate Amlodipine well. Common side effects include:

• Swelling of ankles and feet (peripheral edema)
• Dizziness
• Flushing
• Fatigue
• Nausea
• Palpitations

Serious side effects are rare but include severe low blood pressure, worsening chest pain, and allergic reactions. For a complete breakdown, read our guide on Amlodipine side effects.

Amlodipine does not carry an FDA boxed warning (the most serious type of safety warning).

How Much Does Amlodipine Cost?

One of the best things about Amlodipine is that it's genuinely affordable. Since it's been generic since 2007, prices are low:

• With a discount card: As low as $4 for 30 tablets at pharmacies like Walmart
• Average retail price: About $62 for 30 tablets of 10 mg without discounts
• With insurance: Typically covered as a Tier 1 preferred generic with low copays (often $0-$10)

No prior authorization is generally required for generic Amlodipine. It's covered by most Medicare and commercial insurance plans.
