Why amlodipine can cause ankle swelling

Taking amlodipine and noticing swollen ankles or feet? Here's WHY this common blood pressure medication can cause swelling!

Amlodipine (Norvasc) is a calcium channel blocker used to treat high blood pressure. But one of its most recognizable side effects is peripheral edema—fluid buildup around the ankles and feet.

• WHY DOES AMLODIPINE CAUSE SWELLING?

Amlodipine relaxes small arteries, helping lower blood pressure.

However, these blood vessels can dilate more than the veins, increasing pressure in tiny blood vessels called capillaries.

That pressure can push fluid into surrounding tissues, causing swollen ankles or feet.

• PHARMACIST TAKEAWAY:

• Amlodipine-related swelling is often dose-dependent.

• Swelling is generally more common with 10 mg than 5 mg.

• This type of swelling doesn't necessarily mean you're retaining excess fluid throughout your body.

• Dose adjustments or medication changes may help, depending on your individual situation.

Don't stop or reduce amlodipine without discussing it with your healthcare provider.

• Sudden, painful, red, or one-sided leg swelling needs prompt medical evaluation. Seek emergency care for chest pain or severe shortness of breath.
