🚨 Symptoms that shouldn’t be ignored
Seek urgent medical attention for difficulty breathing or swelling of the face, lips, tongue, or throat, which can indicate a serious allergic reaction. Severe, persistent abdominal pain can rarely indicate pancreatitis, while widespread blistering or peeling skin can indicate a serious skin reaction. nhs.uk
New or severe chest pain, fainting, or significant worsening of angina also deserves urgent assessment. Rarely, worsening angina or a heart attack can occur after starting or increasing amlodipine, particularly in people with severe coronary artery disease. FDA Access Data
Don’t stop amlodipine on your own. Stopping it can allow blood pressure to rise again. If ankle swelling or another side effect is persistent, your clinician can decide whether the dose should be adjusted or another medication considered. nhs.uk
