Amlodipine is a commonly prescribed calcium-channel blocker for high blood pressure and angina. Most people tolerate it well, but some side effects deserve medical attention.
12 symptoms worth taking seriously
-
Severe or rapidly worsening swelling of the feet, ankles, legs, hands, or face.
-
Fainting or severe dizziness, particularly after standing.
-
Very fast, irregular, or unusually slow heartbeat accompanied by feeling unwell.
-
New or worsening chest pain.
-
Severe shortness of breath or difficulty breathing.
-
Swelling of the lips, tongue, face, or throat — possible serious allergic reaction.
-
Severe or persistent abdominal pain, particularly with vomiting.
-
Yellowing of the skin or eyes or unusually dark urine, which can indicate a liver problem.
-
Unusual bleeding or bruising that isn’t explained.
-
Severe muscle weakness or unusual muscle pain.
-
Significant confusion or extreme weakness that develops unexpectedly.
-
A serious skin reaction involving widespread rash, blistering, peeling, or sores in the mouth/eyes.
Some of these are very uncommon and aren’t typical amlodipine reactions. More common effects include ankle swelling, headache, flushing, dizziness, palpitations, and tiredness.
One important point
Don’t stop amlodipine abruptly without medical advice. If ankle swelling is bothering you, your doctor can determine whether it’s from amlodipine or another cause and may adjust the treatment.
If you’re currently taking amlodipine, tell me your dose (e.g., 5 or 10 mg), how long you’ve been taking it, and which symptom you’re experiencing, and I can tell you whether it’s a common side effect or something that warrants prompt medical attention.
