The Food and Drug Administration Tuesday ordered the makers of some antibiotics to add a warning that the medication may increase the risk of tendon problems.

The order covers a potent class of antibiotics, including Cipro and Levaquin. The FDA says the risk of tendon rupture or tendinitis increases among older people, patients who have organ transplants or those who use steroids.

The government wants the drug makers to add a black box warning to the drugs' prescription information, the strongest warning available.
