FDA's MAUDE database holds 12,244 reports that name the brand "FreeStyle Lite" (blood glucose monitoring system), received between October 2007 and August 2026; the manufacturer given most often on reports is Abbott Diabetes Care. Spellings of one product vary from report to report.

430 reports arrived in the 12 months to August 2026, up 174% from 157 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (89.9%) and injury (10.1%); across all system, test, blood glucose, over the counter reports (product code NBW) death is recorded in 0% and malfunction in 90.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are failure to power up (72.6%), incorrect or inadequate test results (9.8%) and incorrect, inadequate or imprecise result or readings (4.2%). The patient problems coded most often are hypoglycemia, loss of consciousness and hyperglycemia. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."

Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
