New York, NY—March 1, 1999
People taking a certain type of antibiotic to fight an infection may want to take it easy for more reasons than one. A common medication prescribed for strep throat, urinary tract infections and other ailments has been shown to cause ruptured tendons in patients who run, jump or lift weights while they are taking the drug and even for a few weeks after they stop, according to Riley Williams, MD, a sports medicine specialist at Hospital for Special Surgery.
Dr. Williams investigated why a class of antibiotics known as fluoroquinolones causes tendons to rupture in certain active or athletic patients. In the laboratory, Dr. Williams found that the antibiotic inhibits the cells that repair tendons and stimulates the production of enzymes that help to break them down. This weakens the tendon, leaving it susceptible to injury. "The fluoroquinolones are a valuable group of antibiotics to fight infection," Dr. Williams notes. "However, it would be prudent for anyone taking this type of antibiotic to avoid sports activities and strenuous exercise."
Dr. William’s research paper won the Best of Show Presentation at this year’s Annual Meeting of the American Academy of Orthopedic Surgeons and the O’Donoghue Award for Best Paper at the Annual Meeting of the American Orthopedic Society for Sports Medicine.
