Our assessment, not the agency’s: severity 5/5 (Critical).

Plain-English summary

OmniDose Medical has issued a voluntary device recall for 23,000 lithium-ion battery packs used in its X4 insulin pump platform. The company has received 41 reports of the battery shutting down without warning, which causes the pump to suspend insulin delivery.

A sudden interruption of basal insulin can lead to rapid-onset diabetic ketoacidosis, a life-threatening condition. The FDA has classified this as a Class I device recall. One serious injury (DKA requiring hospitalization) has been reported; no deaths.

Users should keep a backup insulin delivery method available (pens or syringes), check the lot code on the back of the battery pack, and contact OmniDose support for a free replacement battery. Pump itself does not need to be returned.
