Like all medications, amlodipine, a common drug used to treat high blood pressure and chest pain (angina), comes with the potential for side effects. While many people take amlodipine without experiencing significant problems, it’s crucial to be aware of the possible adverse reactions, including what are considered the worst side effects of amlodipine. This article provides a comprehensive overview of amlodipine side effects, ranging from common annoyances to rare but serious complications, empowering you to understand and manage your health effectively.
Common Side Effects of Amlodipine
The good news is that many side effects associated with amlodipine are mild and tend to subside as your body adjusts to the medication. These common side effects affect more than 1 in 100 people and are often manageable with simple home remedies.
-
Headaches: Headaches are a frequent complaint when starting amlodipine. They usually occur in the first week as your body adapts to the drug’s effects on blood vessels.
Coping strategies: Rest in a quiet, dark room and ensure you are well-hydrated. Over-the-counter painkillers like acetaminophen or ibuprofen, recommended by your pharmacist, can provide relief. Avoid excessive alcohol consumption, as it can worsen headaches. If headaches persist beyond a week or become severe, consult your doctor.
-
Dizziness: Amlodipine lowers blood pressure, which can sometimes lead to dizziness, especially when standing up quickly.
Coping strategies: If you feel dizzy, stop immediately and sit or lie down until the sensation passes. Avoid activities requiring alertness, such as driving, cycling, or operating machinery, until you are no longer dizzy. If dizziness is persistent or bothersome, discuss it with your healthcare provider.
-
Flushing: Flushing, or a sudden feeling of warmth and redness in your face and neck, is another common side effect due to the widening of blood vessels.
Coping strategies: Reduce your intake of triggers like coffee, tea, and alcohol, which can exacerbate flushing. Keeping your environment cool, using a fan, and applying cool water to your face can help. Sipping cold drinks can also provide relief. Flushing usually diminishes within a few days. If it persists or is bothersome, seek medical advice.
-
Pounding Heartbeat (Palpitations): Some individuals experience palpitations, a sensation of a racing or pounding heart, after taking amlodipine.
Coping strategies: If palpitations occur regularly after taking amlodipine, try taking your dose when you can rest. Reducing stimulants like alcohol, caffeine, and nicotine, and avoiding large meals, can also help minimize palpitations. If you have a history of heart conditions, and palpitations are prolonged, worsen, or cause concern, consult your doctor promptly.
-
Swollen Ankles (Edema): Amlodipine can sometimes cause fluid retention, leading to swelling in the ankles and feet.
Coping strategies: Elevating your legs while sitting can help reduce ankle swelling. If swollen ankles become uncomfortable or do not improve, discuss this with your doctor or pharmacist.
If these common side effects persist, worsen, or become bothersome despite self-care measures, it’s important to consult your doctor or pharmacist for further guidance.
Serious Side Effects of Amlodipine: When to Seek Immediate Medical Help
While serious side effects from amlodipine are rare, occurring in less than 1 in 10,000 people, it’s vital to recognize them and know when to seek immediate medical attention. These are potentially the “worst side effects of amlodipine” due to their severity and potential for long-term health consequences if untreated.
-
Pancreatitis: Although rare, amlodipine can, in some cases, trigger pancreatitis, inflammation of the pancreas.
Symptoms requiring immediate medical attention: Severe stomach pain, which may radiate to your back, accompanied by nausea, vomiting, and diarrhea (possibly with blood). If you experience these symptoms, seek immediate medical help.
-
Liver Problems: Amlodipine can rarely affect liver function.
Symptoms requiring immediate medical attention: Yellowing of the skin or whites of the eyes (jaundice), dark urine, pale stools, persistent fatigue, or unexplained abdominal pain could indicate liver issues. Contact your doctor immediately if you notice these signs.
-
Heart Attack (Myocardial Infarction): In rare instances, especially in individuals with pre-existing angina, amlodipine may not adequately control chest pain and could potentially be associated with a heart attack.
Symptoms requiring immediate action – Call 999 (or your local emergency number) immediately: New, worsening, or persistent chest pain that doesn’t subside after a few minutes, or is different from your usual angina pain. Chest pain can be a critical sign of a heart attack and requires immediate evaluation. Do not drive yourself to the hospital; call for emergency medical services.

Serious Allergic Reactions to Amlodipine (Anaphylaxis)
A severe allergic reaction to amlodipine, known as anaphylaxis, is a rare but life-threatening emergency.
Symptoms requiring immediate action – Call 999 (or your local emergency number) immediately:
- Sudden swelling of the lips, mouth, throat, or tongue.
- Difficulty breathing, wheezing, gasping for air, or feeling like you’re choking.
- Tightness in the throat or difficulty swallowing.
- Blue, gray, or pale skin or lips (more noticeable on palms or soles of feet in darker skin tones).
- Sudden confusion, drowsiness, or dizziness.
- Fainting or unresponsiveness.
- In a child, limpness, floppiness, unresponsiveness, head tilting, or difficulty focusing.
These symptoms can be accompanied by a rash that is swollen, raised, itchy, blistered, or peeling. Anaphylaxis requires immediate medical treatment in a hospital. Do not drive yourself to the hospital; call for emergency medical services.

Reporting Side Effects
If you experience any suspected side effects from amlodipine, it’s important to report them. Reporting side effects helps monitor the safety of medications.
