Amlodipine is a calcium channel blocker commonly used to treat high blood pressure and some types of chest pain (angina). Many people take it safely, but some side effects should not be ignored.
Common side effects
- Swelling of the ankles or feet (edema) — one of the most common effects
- Dizziness or lightheadedness
- Flushing or feeling warm
- Headache
- Tiredness
- Heart palpitations (feeling your heartbeat more strongly or quickly)
Side effects that should be checked by a healthcare professional
- New or worsening swelling, especially if it is severe or associated with shortness of breath
- Fainting or severe dizziness
- Very low blood pressure symptoms (weakness, confusion, feeling like you may pass out)
- New or worsening chest pain
- Signs of an allergic reaction (face/lip/tongue swelling, trouble breathing, severe rash)
Important:
- Do not stop amlodipine suddenly without medical advice, because your blood pressure may rise again.
- Keep track of your blood pressure and discuss bothersome side effects with your clinician; dose adjustments or alternatives may be possible.
If you are taking amlodipine, tell me your dose (e.g., 5 mg or 10 mg) and what symptom you’re noticing, and I can help you understand whether it is a known side effect or something that needs prompt attention.
