The U.S. Food and Drug Administration (FDA) has decided Cipro and its class of antibiotics known as fluoroquinolones will now bear a "black box" after reports confirmed that the drugs increase the risk of tendinitis and tendon rupture.

The federal agency said that the warning on the drug is necessary to ensure that the drugs' benefits outweigh the risks. It is also requiring the manufacturers to provide a medication guide to patients about the potential side effects of tendon rupture

Tests for a new drug to combat the highly infectious and deadly disease tuberculosis (TB) show it can be cured in much less time. A new study finds that adding the antibiotic moxifloxacin to standard TB medicines also made the drugs 17 percent more effective. Adding moxifloxacin also shortened the time it takes to cure TB to just four months.

Research done in Brazil by scientists from Johns Hopkins University presented the report at an American Society for Microbiology conference in Chicago
