Bristol-Myers Squibb is warning against the use of the antibiotic drug Tequin in diabetic patients, the U.S. Food and Drug Administration said on Thursday. The company is also strengthening its warning that the drug can cause low and high blood sugar levels in patients, the FDA said. Since Tequin was approved in 1999, there have been "rare cases of life-threatening events" involving patients who took the drug, the agency said. --SP 22 48 Local Time 19 48 GMT
