What you should NOT do
Don’t stop amlodipine suddenly or change the dose yourself. If side effects are troublesome, your doctor can consider adjusting the dose or changing treatment. nhs.uk
Also, avoid grapefruit and grapefruit juice while taking amlodipine because they can increase the chance of side effects. nhs.uk
Get urgent medical help if
You develop difficulty breathing, swelling of the lips/tongue/throat, severe chest pain, fainting, or sudden severe abdominal pain. These can indicate a serious problem rather than an ordinary medication side effect. nhs.uk
If you tell me your amlodipine dose (2.5, 5, or 10 mg) and the particular side effect you’re experiencing, I can explain how common it is and what can usually be done about it.
