Drugs that Cause Atrial Fibrillation

Certain medications increase your risk of atrial fibrillation (AFib). Knowing which ones can help you and your doctor make informed decisions.

Stimulants, such as methylphenidate and amphetamines, can trigger irregular heartbeats. Their effect on the heart’s electrical system increases the chance of developing AFib, especially in predisposed individuals. Close monitoring is crucial if you’re using stimulants.

Beta-blockers, while often prescribed for heart conditions, can paradoxically increase AFib risk in some people, particularly when stopping the medication abruptly. A gradual reduction under medical supervision is recommended to minimize this risk.

Certain antibiotics, including erythromycin and some fluoroquinolones, can affect the heart’s rhythm and conduction pathways. While rare, AFib is a possible side effect, and your doctor should be aware of your heart history if prescribed these medications.

Non-steroidal anti-inflammatory drugs (NSAIDs), like ibuprofen and naproxen, used long-term, may indirectly increase AFib risk by impacting blood pressure and fluid balance. Consult your doctor about alternatives if you have concerns.

Some antipsychotics have been linked to AFib, though the association is often complex and influenced by other health factors. Regular heart monitoring is advisable if you’re on these medications.

This information doesn’t encompass all medications that can contribute to AFib. Always discuss your medication history and any concerns about AFib with your physician. They can assess your individual risk factors and provide personalized advice.
