12 Amlodipine Side Effects You Should Know About

Amlodipine is a calcium-channel blocker commonly prescribed for high blood pressure and angina. Most people tolerate it well, but side effects can occur. (nhs.uk)

Common effects

1. Swollen ankles, feet or legs — one of the most characteristic effects.
2. Headache
3. Dizziness or light-headedness
4. Sleepiness
5. Flushing or feeling unusually warm
6. Palpitations or a more noticeable heartbeat
7. Nausea
8. Abdominal discomfort
9. Constipation or diarrhea
10. Fatigue or weakness
11. Muscle cramps
12. Visual disturbances, including blurred or double vision. (nhs.uk)

🚨 Rare but potentially serious

Seek urgent medical attention for difficulty breathing or swelling of the face, lips, tongue or throat, which can indicate a severe allergic reaction. Severe, persistent abdominal pain—especially with vomiting—can rarely indicate pancreatitis. Serious skin reactions are also possible but very uncommon. (nhs.uk)

What about swollen ankles?

This is particularly worth knowing about. Amlodipine-related edema commonly affects the ankles and feet and can develop during the first weeks or months of treatment or after a dose increase. It is usually not dangerous, but troublesome swelling should be discussed with your doctor because the dose or treatment may need adjustment. (SPS – Specialist Pharmacy Service)

Don’t stop amlodipine on your own. Stopping it can allow your blood pressure to rise and may increase cardiovascular risk. If side effects are bothering you, speak with your doctor or pharmacist about alternatives or dose adjustments. (nhs.uk)

Bottom line: Ankle swelling, headache, dizziness, flushing, palpitations and fatigue are among the more recognizable effects. Severe allergic symptoms, severe abdominal pain, fainting, chest pain or serious breathing problems require prompt medical attention.
