Also, don’t stop amlodipine on your own because you’re experiencing side effects. The NHS advises continuing it unless a doctor tells you to stop; your clinician can decide whether the dose should be adjusted or another medicine used.

One especially important point: ankle swelling from amlodipine is common and doesn’t necessarily mean you’ve developed heart failure. However, new or worsening swelling should still be discussed with your doctor, particularly if it comes with breathlessness or other concerning symptoms.
