The FDA has told companies that the drugs must now carry "black box" warnings alerting doctors and patients that the drugs can increase risk of tendinitis and tendon rupture in some patients. Fluoroquinolones have carried similar warnings for years, but officials say they continue to receive reports of safety problems. A "black box" warning is the FDA's sternest warning. "We have seen continuing reports of tendon rupture so we are trying to increase awareness," says Edward Cox, MD, director of the FDA's Office of Antimicrobial Products. The warning applies to drugs of the fluoroquinolone class, including Cipro, Cipro XR, Proquin XR, Levaquin, Floxin, Noroxin, Avelox, Factive, and marketed generics.

"The use of fluoroquinolones has a place in the treatment of serious bacterial infections -- such as certain types of bacterial pneumonia -- where the benefits of these drugs outweigh the risks," Dr. Edward Cox, director of the FDA's Office of Antimicrobial Products, said in an agency news release. What kinds of infections should not be treated with these antibiotics? According to the agency, the risks generally outweigh the benefits of fluoroquinolone treatment for patients with acute sinusitis, acute or chronic bronchitis and uncomplicated urinary tract infections.

The use of ciprofloxacin and other antibiotics of the class of fluoroquinolones may be associated with disruption of the normal functions of connective tissue, including tendon rupture, tendonitis and retinal detachment. These observations reported in a number of journals resulted in the drugs currently having a black box warning physicians and patients of the potential deleterious side effects. The endothelium, the thin layer of cells that line our arteries and veins, is like a gatekeeper, controlling the movement of materials into and out of the bloodstream. Endothelial cells are held tightly together by specialized proteins that function like strong ropes (red) and others that act like cement (blue). NIH Image Gallery “A natural tissue to worry about is the aorta, a blood vessel that relies heavily on having a sound connective tissue component – called the extracellular matrix – to maintain its integrity,” said first author Dr. Le Maire, director of research in the division of cardiothoracic surgery, vice-chair for research and professor of surgery and of molecular physiology and biophysics at Baylor College of Medicine. Two retrospective clinical studies looked at the possible association between fluoroquinolones and cardiovascular problems. “They found that patients who received fluoroquinolones had a higher risk for aneurysms (formation of balloon-like areas in the aorta that weaken the integrity of the vessel), ruptures or dissections (tears in the wall) than patients who did not receive the antibiotics. These antibiotics have been on the market for more than 30 years. Physicians and patients assumed that they were quite safe. These drugs were routinely prescribed for sinus, lung and urinary tract infections with barely a second thought. But now the FDA has issued a stern warning (May 12, 2016): “The U. Food and Drug Administration is advising that the serious side effects associated with fluoroquinolone antibacterial drugs generally outweigh the benefits for patients with sinusitis, bronchitis, and uncomplicated urinary tract infections who have other treatment options. For patients with these conditions, fluoroquinolone should be reserved for those who do not have alternative treatment options. “An FDA safety review has shown that fluoroquinolones when used systemically (i.e. tablets, capsules, and injectable) are associated with disabling and potentially permanent serious side effects that can occur together.
