Fluoroquinolones, long associated with Achilles tendonitis and rupture, have been demonstrated to increase your risk of aortic dissection (a tear in the wall of the major artery, allowing blood to flow between the layers) or aortic rupture, which can lead to death.

Even though “black-box” warnings are now attached to them, fluoroquinolones are still often prescribed for upper respiratory infections or urinary tract infections.

Antibiotic use can trigger a permanent change in your gut microbiome, which accounts for nearly 80% of your immune system function, so it is important to use antibiotics only when absolutely necessary.

You may reduce your risk of bacterial and viral infections by supporting your immune system through simple lifestyle measures, such as quality sleep, fermented foods, regular exercise and optimizing your vitamin D level.
