The U.S. Food and Drug Administration has issued enhanced warnings on a group of strong antibiotics, Reuters reports.
The U.S. Food and Drug Administration (FDA) has enhanced warnings of side effects of a group of strong antibiotics used to treat a variety of respiratory and urinary tract infections and limited their use to patients with no alternatives.
The antibiotics known as fluoroquinolones include Johnson & Johnson’s Levaquin, Bayer’s Cipro extended-release tablets and Merck Inc’s Avelox.
The FDA originally added a box warning to the antibiotics in July 2008 to inform users about the increased risk of tendinitis; however, the box warning was updated on Tuesday to highlight the disabling and potentially permanent side effects of the drugs.
