There are some things you can do to try and prevent recurrent spells of atrial fibrillation. You may need to reduce or eliminate your intake of caffeine and alcohol, which can overstimulate the heart and trigger an episode of atrial fibrillation. It’s also important to be careful when taking over-the-counter (OTC) medications. Some, such as cold medicines containing pseudoephedrine, contain stimulants that can trigger atrial fibrillation. Also, some OTC medications adversely interact with anti-arrhythmic medications.

You may need to make lifestyle changes that improve the overall health of your heart, especially to prevent or treat conditions such as high blood pressure. Your doctor may advise that you:

  • Eat heart-healthy foods
  • Reduce your salt intake, which can help lower blood pressure
  • Quit smoking
  • Increase your physical activity
  • Avoid alcohol
