Should I tell my cardiologist that I take a CoQ10 supplement?

Richard T. Leshner, DO
Cardiology (Cardiovascular Disease)
You should tell your cardiologist that you take a coenzyme Q10 (CoQ10) supplement. CoQ10 may be used by people with congestive heart failure (CHF) and others with cardiac disease. However, it prolongs a portion of the electrocardiogram called the QT interval, and if you mix that with certain medications that cardiologists use commonly, it can be deadly. You really have to bring that information to your physician. You think it’s a supplement, it isn’t important, but it truly is important. Your cardiologist needs to know everything you take.
