Cipro and Levaquin belong to a class of antibiotics known as Fluoroquinolones. A number of different manufacturers sell Fluoroquinolones under a variety different names, including the generic drug name, Ciprofloxin.
The risk of tendon damage was included with a list of other possible side effects on Cipro and Levaquin packaging. Then three years ago, alarmed by an increasing number of tendon injuries related to the use of Levaquin and Cipro, an advocacy group known as Public Health forced the Food and Drug Administration (FDA) to add a black box warning to the label—the most serious warning the FDA issues.
Cipro and Levaquin are prescribed for the following types of bacterial infections.
 Bronchitis
 pneumonia
 Chlamydia
 Urinary Tract Infections
 Skin infections
 Gonorrhea
 Prostate Infections
Levaquin can also be used to reduce the effects of exposure to Anthrax. It is the most powerful antibiotic currently available.
Tendons are tight bands of collagen fiber that connect muscle to bone. A ruptured or torn tendon is extremely painful and can be debilitating.
Attorney Eric Chaffin believes that the drugs may push active people over the edge. "If you are a runner or a fitness instructor," says Chaffin, "or a person who regularly pushes muscles and tendons to extremes, the addition of Cipro or Levaquin might be enough to cause damage."
"You may want to take it easy for a week or ten days after using these drugs," he says. "Many people who contacted us are runners. People who have been on the drugs are active and some of those people I think should have been warned that there is a hyper risk for them."
Lawsuits related to these drugs are just beginning to take shape. "The spontaneous tendon rupture cases are the ones we have focused on. Typically they have suffered a tendon rupture simultaneously or within days of taking the drug." says Chaffin. "We have a number of cases, and we believe there are many more out there."
