Amlodipine is a calcium channel blocker commonly used for high blood pressure and chest pain (angina). Most people tolerate it well, but it can cause side effects in some users.
Here are 12 common things to watch for:
- Swelling (edema) – especially ankles, feet, or lower legs (one of the most common effects)
- Flushing – feeling warm or red in the face or neck
- Headache – often mild to moderate
- Dizziness or lightheadedness – especially when standing up quickly
- Fatigue or tiredness – feeling unusually low energy
- Palpitations – feeling your heartbeat is fast or noticeable
- Nausea – sometimes mild stomach upset
- Abdominal discomfort – bloating or cramping in some people
- Sleepiness – drowsiness or reduced alertness
- Low blood pressure symptoms – such as weakness or fainting (less common but important)
- Gum overgrowth (gingival swelling) – rare but known with long-term use
- Muscle cramps or aches – occasional and usually mild
Less common but serious signs (seek medical attention):
- Severe swelling or sudden weight gain
- Chest pain worsening instead of improving
- Severe dizziness or fainting
- Signs of allergic reaction (rash, swelling of face/lips, trouble breathing)
Most side effects happen because amlodipine relaxes blood vessels, which lowers pressure but can also cause fluid shifts in the body.
