Boxed Warning on Medication Label

The FDA put its strongest warning on the drug packaging.
You should know:
  • Fluoroquinolones carry a higher chance of tendinitis and tendon rupture.
  • It's greater for those over 60; in kidney, heart, and lung transplant recipients; and those taking steroid medications.
  • Stop taking the fluoroquinolone at the first sign of tendon pain, swelling, or inflammation. Avoid exercise and use of the affected area, and immediately ask your doctor to switch to a non-fluoroquinolone drug.

Benefits vs. Risks

For some types of sinusitis, chronic bronchitis, and urinary tract infections, the risks of fluoroquinolone drugs are greater than the benefits for most people.
For some serious infections, like pneumonia or infections inside the abdomen, the benefits of fluoroquinolone drugs outweigh the risks.
Your health care provider can talk to you about your best choice.
