Amlodipine: A Complete Guide to Uses, Dosage, and Side Effects

What Is Amlodipine?

Amlodipine is a calcium channel blocker that relaxes blood vessels, making it easier for the heart to pump blood. Available as a generic drug or under the brand name Norvasc, it’s commonly used to:

• Lower high blood pressure.

• Treat chest pain (angina) caused by coronary artery disease.

How It Works:

By blocking calcium from entering the heart and artery walls, Amlodipine:

• Widens blood vessels for better blood flow.

• Reduces strain on the heart, lowering blood pressure.

Amlodipine Uses

1. High Blood Pressure (Hypertension)

Untreated hypertension can damage the heart, kidneys, and brain. Amlodipine helps maintain healthy blood pressure levels, reducing risks of stroke and organ damage.

2. Coronary Artery Disease (CAD)

Amlodipine improves blood flow to the heart, alleviating angina (chest pain) and preventing heart attacks. It’s often combined with other medications but isn’t used for immediate angina relief.

Amlodipine Dosage Guidelines

Available Strengths:

• 2.5 mg, 5 mg, and 10 mg tablets.

Typical Dosage:

• Adults: Start with 5 mg once daily; may increase to 10 mg.

• Elderly/Liver Issues: Lower doses (2.5 mg) often recommended.

Key Tips:

• Take at the same time daily for consistent results.

• Never double a missed dose. Skip it if close to the next scheduled time.

Common Side Effects of Amlodipine

Most side effects are mild and temporary:

• Swelling (Edema): Often in ankles/legs due to fluid retention.

• Dizziness or Fatigue: Especially when standing quickly.

• Constipation: Manage with fiber-rich foods and hydration.

• Weight Gain: Linked to fluid retention, not fat accumulation.

Rare but Serious Side Effects:

• Chest pain, irregular heartbeat, severe allergic reactions (rash, swelling).

• Seek immediate care if you experience difficulty breathing or fainting.

Who Should Avoid Amlodipine?

Amlodipine isn’t safe for everyone. Avoid it if you:

• Have severe low blood pressure or aortic stenosis.

• Experience allergic reactions to calcium channel blockers.

• Suffer from liver disease (dosage adjustments may be needed).

Always inform your doctor about:

• Other medications (e.g., simvastatin, blood pressure drugs).

• Pregnancy, breastfeeding, or plans to conceive.

Managing Side Effects

Swelling (Edema):

• Wear compression socks.

• Elevate legs when resting.

• Ask your doctor about reducing the dose.

Constipation:

• Increase fiber intake (fruits, vegetables, whole grains).

• Stay hydrated and exercise regularly.

Amlodipine is a first-line treatment for hypertension and angina. Swelling and dizziness are common but manageable side effects. Never self-adjust your dosage - follow your doctor’s plan strictly.
