Amlodipine is a commonly prescribed medicine for high blood pressure and certain types of angina. Like all medicines, it can cause side effects, although many people take it without serious problems.
Knowing what to watch for can help you recognize common reactions and know when to contact your healthcare professional.
1. Swollen Ankles or Feet
Swelling around the ankles, feet, or lower legs is one of the more common side effects of amlodipine. It can be more noticeable at higher doses.
What may help: Elevating your legs when resting and discussing the swelling with your doctor can help. Don’t stop amlodipine on your own.
2. Dizziness
Amlodipine can sometimes cause dizziness, particularly when your blood pressure becomes lower than your body is used to.
What may help: Rise slowly from sitting or lying down. If dizziness is persistent or severe, speak with your healthcare professional.
3. Headache
Headaches can occur, particularly when starting treatment. They may improve as your body adjusts to the medicine.
What may help: Rest, stay adequately hydrated, and discuss persistent headaches with your doctor.
4. Flushing or Feeling Warm
Some people experience a warm or flushed face or neck. This occurs because amlodipine relaxes blood vessels.
What may help: Avoid triggers such as excessive heat and discuss persistent symptoms with your healthcare professional.
5. Noticeable Heartbeat
Amlodipine can sometimes cause palpitations, meaning you become more aware of your heartbeat.
What to do: If palpitations are frequent, prolonged, or accompanied by chest pain, fainting, or severe shortness of breath, seek medical attention promptly.
6. Tiredness or Fatigue
Feeling unusually tired or weak can occur in some people taking amlodipine.
What may help: Get adequate rest and discuss persistent fatigue with your doctor, particularly if it interferes with everyday activities.
7. Nausea or Stomach Discomfort
Some people experience nausea or abdominal discomfort while taking amlodipine.
What may help: Smaller meals and avoiding foods that trigger stomach upset may help. Persistent symptoms should be discussed with a healthcare professional.
8. Constipation or Diarrhea
Digestive changes, including constipation or diarrhea, have been reported with amlodipine.
What may help: Adequate fluids and a balanced diet containing fiber can support normal bowel function.
9. Sleepiness
Some people may experience sleepiness while taking amlodipine.
What may help: Avoid driving or operating machinery if you feel unusually sleepy or dizzy.
10. Muscle or Joint Discomfort
Muscle pain, cramps, and joint-related symptoms have been reported, although these are less common.
What to do: If new or persistent muscle or joint symptoms develop, tell your healthcare professional so other possible causes can be considered.
11. Changes in Gum Tissue
Rarely, amlodipine has been associated with gingival hyperplasia, in which the gums become enlarged or swollen.
What may help: Maintain good oral hygiene and arrange a dental evaluation if you notice persistent gum enlargement.
12. Low Blood Pressure or Fainting
Amlodipine lowers blood pressure. In some people, this can contribute to excessive blood-pressure lowering, dizziness, or fainting.
What to do: If you faint or repeatedly feel extremely lightheaded, contact your healthcare professional promptly.
When Should You Get Urgent Medical Help?
Most amlodipine side effects are mild or moderate. However, rare serious reactions can occur.
Seek urgent medical attention for difficulty breathing, swelling of the face, lips, tongue, or throat, severe skin reactions, severe or persistent abdominal pain, fainting, or new severe chest pain.
Should You Stop Amlodipine If You Have Side Effects?
Don’t stop amlodipine without speaking to your doctor. Stopping blood-pressure treatment without medical guidance can allow your blood pressure to rise and may increase cardiovascular risk. Your healthcare professional can determine whether your dose needs adjustment or whether another treatment is more appropriate.
Final Takeaway
Amlodipine is generally well tolerated, but side effects such as ankle swelling, dizziness, headache, flushing, palpitations, fatigue, and digestive symptoms can occur. If a side effect is persistent, bothersome, or worsening, discuss it with your doctor or pharmacist rather than stopping the medicine yourself.
