Diabetic patients taking oral fluoroquinolones, a frequently prescribed class of antibiotics, were found to have a higher risk of severe blood sugar-related problems than diabetic patients taking other kinds of antibiotics, according to a recent study. The increased risk was low, but clinicians should consider the higher risk when treating diabetic patients with fluoroquinolones, especially moxifloxacin, and prescribe them cautiously, the study’s authors concluded.
