TikTok Doc Reveals Common Amlodipine Side Effect
16 Oct
Summary
- Amlodipine can cause ankle swelling by dilating blood vessels and increasing capillary pressure.
- Swelling, also known as peripheral edema, commonly affects both ankles and feet.
- Seek medical advice for new, persistent, or worsening swelling; do not stop medication.

A prevalent blood pressure medication, Amlodipine, may cause uncomfortable side effects that patients should be aware of. A TikTok pharmacist recently highlighted how the drug can lead to swollen ankles due to its mechanism of action.
Amlodipine belongs to the calcium channel blocker class, designed to relax and widen blood vessels for easier blood flow. However, this dilation can increase capillary pressure, pushing fluid into the extremities and resulting in peripheral edema, most commonly affecting the ankles and feet.
While this swelling is a known side effect, it can vary in severity. Patients experiencing new, persistent, or worsening swelling should consult a healthcare professional. It is crucial not to discontinue Amlodipine without medical guidance, as uncontrolled high blood pressure poses significant health risks.
