Amlodipine is a commonly prescribed calcium channel blocker used for high blood pressure and chest pain (angina). Most people tolerate it well, but like all medications, it can cause side effects.
Here are 12 of the most common things to watch for, especially if you’ve just started it or your dose was increased:
🩺 1. Swollen ankles or feet (edema)
This is the most common side effect. It happens because blood vessels relax and fluid can pool in the lower legs.
🩸 2. Flushing (feeling warm or red in the face)
A sudden warm sensation, especially early in treatment.
💓 3. Fast or pounding heartbeat
Some people notice palpitations as the body adjusts.
😴 4. Tiredness or fatigue
Can happen as blood pressure lowers.
🤕 5. Headache
Often mild and improves after a few days.
😵 6. Dizziness or lightheadedness
More likely when standing up quickly.
🍽️ 7. Nausea or mild stomach discomfort
Usually temporary and mild.
🦵 8. Muscle cramps
Less common, but reported in some patients.
😐 9. Gum swelling (gingival overgrowth)
Rare, but long-term use can sometimes affect gums.
🫀 10. Worsening or new chest discomfort (rare)
Usually in people with existing heart disease—needs medical attention.
🧠 11. Sleepiness or “slowed feeling”
Not dangerous, but can affect daily energy.
⚖️ 12. Low blood pressure symptoms
- Weakness
- Blurred vision
- Feeling faint
More likely if combined with other blood pressure medications.
🚨 When to seek medical help
Get urgent advice if you notice:
- Severe swelling or sudden weight gain
- Chest pain
- Fainting
- Very fast or irregular heartbeat
- Allergic reaction (rash, swelling of face/lips)
🧠 Simple takeaway
