Rare but serious reactions
Get emergency help for difficulty breathing, swelling of the lips/tongue/throat, or a severe allergic reaction. Rarely, amlodipine has also been associated with severe skin reactions and acute pancreatitis. nhs.uk
Don’t stop amlodipine suddenly on your own. It’s prescribed to control blood pressure and/or prevent angina, and stopping it without medical advice can be harmful. If ankle swelling or another side effect is troublesome, a doctor can decide whether the dose or medication should be changed. nhs.uk+1
