Get urgent medical help if
You develop severe difficulty breathing, swelling of the face/lips/tongue, fainting, severe chest pain, or a serious allergic reaction.
Don’t stop amlodipine suddenly or change the dose without discussing it with your prescriber. If you’re experiencing a particular symptom, tell me your dose, how long you’ve been taking it, and what you’re feeling, and I can explain whether it’s a recognized side effect and how urgent it may be.
