Amlodipine is a widely prescribed calcium channel blocker for high blood pressure and angina. While generally safe, like all medications it can cause side effects—some mild, some serious. Here’s a clear, evidence-based list of 12 side effects you should never ignore.
12 Side Effects of Amlodipine That Need Attention
1. Swelling of Feet, Ankles, or Hands (Edema)
- Most common side effect
- Usually mild, but sudden or severe swelling may signal heart or kidney issues
2. Dizziness or Lightheadedness
- Caused by blood pressure dropping too much
- Increases risk of falls or fainting
3. Flushing or Redness of Face
- Usually mild, but persistent or severe redness should be monitored
4. Palpitations / Rapid Heartbeat
- Heart may race as it adjusts to lower blood pressure
- Could indicate arrhythmia if persistent
5. Fatigue or Extreme Tiredness
- Low blood pressure reduces oxygen delivery → tiredness
- Persistent fatigue may require dosage adjustment
6. Shortness of Breath
- Could signal fluid retention or worsening heart function
- Requires urgent medical evaluation
7. Nausea or Stomach Pain
- Usually mild digestive upset
- Persistent vomiting may need evaluation
8. Severe Headaches
- Sometimes due to blood pressure fluctuations
- Can indicate hypertensive or vascular complications
9. Chest Pain / Angina Worsening
- Rare but serious
- Seek immediate medical attention if chest discomfort occurs
10. Fainting
- Caused by sudden drop in blood pressure
- Dangerous if it leads to injury
11. Yellowing of Skin or Eyes (Jaundice)
- Rare, but may indicate liver issues from the medication
12. Unusual Weight Gain
- Could signal fluid retention and worsening heart failure
⚠️ Important Notes
- Mild side effects (flushing, minor swelling) are common and sometimes manageable
- Severe or sudden side effects (chest pain, fainting, severe swelling, jaundice) require immediate medical attention
- Never stop amlodipine abruptly—talk to your doctor before making changes
