FDA's MAUDE database holds 13,859 reports that name the brand "Granuflo" (dry acid concentrate for bicarbonate dialysis), received between October 2012 and October 2016; the manufacturer given most often on reports is Fresenius Medical Care North America. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, and none 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 death (82.1%) and injury (17.9%); across all dialysate concentrate for hemodialysis (liquid or powder) reports (product code KPO) death is recorded in 76.9% and malfunction in 5%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are insufficient device problem information (99.5%), device operates differently than expected (0%) and patient-device incompatibility (0%). The patient problems coded most often are death, cardiac arrest and myocardial infarction. 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.
