New FAQ: Which antibiotics are less liable to cause an A-Fib attack?
A question from Ellen McCall lead me to turn to our world-wide A-Fib.com Advisory Board for an answer. Several EPs shared their opinions, research data and insights from their practices in answer to this question:
FAQ: “Which antibiotics are less liable to cause an A-Fib attack? How is Clindamycin for dental work? In the past I reacted to Azithromycin and Advil.”
Our A-Fib Advisory Board Offers Expert Opinions
One EP’s response: “There is no particular association that I can think of or have seen with antibiotics, but likely more of a personal idiosyncratic reaction to the drug. Everybody is different and has a different trigger.”
From another EP: “Most [antibiotics] do not change the way the heart’s electrical system functions other than prolonging the QT interval, which should have the opposite effect. In the quinolone family, (antibiotics) like Levofloxacin and Ciprofloxacin act like antiarrhythmics.
However, some antibiotics have worse gastric tolerance effects like Azithromycin and Erythromycin which can become a trigger for A-Fib by GI stimulation such as nausea or reflux. Medication to counter that side effect can be used, such as acid reducers.”
