🚨 When to seek emergency help
Call emergency services immediately for severe difficulty breathing, swelling of the tongue/throat, severe chest pain, fainting, or a severe blistering/peeling skin reaction. Medicines.org.uk
Also, don’t stop amlodipine on your own because you’re experiencing a side effect. A doctor can determine whether the dose should be changed or another blood-pressure medicine considered. nhs.uk
If you tell me your amlodipine dose (e.g., 5 mg or 10 mg) and which symptom you’re experiencing, I can explain how concerning it is and what to do next.
