Amlodipine: What You Need to Know

When working with amlodipine, a calcium channel blocker used to lower blood pressure and treat angina. Also known as Norvasc, it relaxes the smooth muscles of blood vessels, making it easier for the heart to pump.

How Amlodipine Fits Into Blood Pressure Care

The drug sits inside a family of medicines called calcium channel blockers. These agents work by blocking calcium entry into vascular muscle cells, which reduces vessel tension and drops hypertension. Because it targets the arteries, amlodipine is a go‑to option for patients who need steady, 24‑hour control without frequent dosing.

Typical daily doses range from 2.5 mg to 10 mg, tailored to the individual's blood pressure reading and response. Starting low helps avoid a jump in peripheral edema, the most common side effect. If swelling appears, doctors may lower the dose or add a diuretic. Other frequent reactions include headache, flushing, and a mild feeling of dizziness, especially after the first few days.

One of the trickier aspects of amlodipine therapy is managing drug interactions. Strong CYP3A4 inhibitors like ketoconazole or grapefruit juice can raise blood levels and increase the risk of side effects. Conversely, enzyme inducers such as rifampin may lower its effectiveness, leaving blood pressure uncontrolled. Always list every medication, herb, or supplement you take to your prescriber.

People with liver disease, severe heart failure, or a history of low blood pressure need extra caution. Regular monitoring—checking blood pressure, heart rate, and signs of swelling—keeps the therapy on track. Adjustments are usually simple: a tweak in dose or an added drug to counteract edema.
