Hypoglycemia in patients treated with linezolid.

Hypoglycemia was not previously known to be a linezolid-associated adverse reaction. A case report describing symptomatic hypoglycemia in a linezolid recipient prompted a review of the US Food and Drug Administration Adverse Event Reporting System, which demonstrated a relationship between linezolid and hypoglycemia. A warning with this information was added to the linezolid package insert.
