1,011 medical device reports received by FDA name the brand "Kit MMT-105NNBLW1 NovoNordisk Blue OUS1" (syringe piston); the manufacturer given most often on reports is Companion Medical; received from January 2023 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

655 reports arrived in the 12 months to August 2026, up 155% from 257 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 (99.4%) and injury (0.6%); across all syringe, piston reports (product code FMF) death is recorded in 0.1% and malfunction in 88.5%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are patient device interaction problem (33.8%), physical resistance/sticking (24.5%) and data problem (17.9%). The patient problems coded most often are hyperglycemia, hypoglycemia and fatigue. 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."
