Can taking Azithromycin cause any serious heart problems? I've used it quite a bit, but recently stumbled upon this info and it got me a bit worried. Should I be considering different antibiotics? I was on Azithromycin for a 10-day course for a UTI once.

Azithromycin can indeed have an effect on the heart, particularly in individuals with certain risk factors such as existing heart conditions or those who are prone to heart rhythm abnormalities. It is important to be cautious when using Azithromycin and to discuss any concerns with your healthcare provider. If you have a history of cardiac issues or if you are worried about potential risks, it may be advisable to consider alternative antibiotics. I recommend discussing your concerns with your healthcare provider to determine the best course of action for your specific situation.
