How serious is it, by FDA’s class?
Class II, the middle of FDA’s three classes.
“Products that might cause a temporary health problem, or pose only a slight threat of a serious nature. Example: a drug that is under-strength but that is not used to treat life-threatening situations.”
openFDA, in plain words, its enforcement report fields.
“Class II is a situation in which use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.”

What’s wrong with it?
Medtronic is recalling certain lots of Medtronic MiniMed Paradigm Reservoirs MMT-326A (1.8mL) and MMT-332A (3.0mL) used with Medtronic Paradigm insulin pumps because they may have increased risk for leaking.

Which ones are recalled?
Medtronic MiniMed Paradigm Reservoirs, Model No: MMT-326A (1.8mL) and MMT-332A (3.0mL) The model MMT-326A and MMT-332A are syringe type insulin reservoirs intended for use with Medtronic Paradigm series insulin infusion pumps. The two reservoirs are identical except for barrel length and as a result, maximum insulin capacity. The MMT-326A holds a maximum of 1.8ml of insulin whereas the longer MMT-332A reservoir can hold up to 3.0ml of insulin. Both reservoirs are supplied sterile and are labeled for single use. Typically, the reservoir is replaced every tow or three days at the time of infusion set replacement. The Paradigm reservoirs have a shelf life of three years post sterilization.

What this record can’t tell you
- Whether your own one is affected: compare the codes, dates and numbers above with yours. When unsure, ask the firm or the store.
- Where it went after the firm’s first shipments. FDA’s words cover the firm’s initial distribution, and, in FDA’s words, “subsequent distribution by the consignees to other parties may not be included.”
- How many have been returned, corrected or destroyed: FDA’s report doesn’t say.
- Whether anyone was hurt or fell ill: the report doesn’t say.
- How current it is: openFDA publishes FDA’s Enforcement Report weekly, after FDA does, and a firm can announce a recall weeks before it appears there. openFDA’s own caution: “This data should not be used as a method to collect data to issue alerts to the public, nor should it be used to track the lifecycle of a recall.”
- A product with no recall here isn’t safe by that: FDA’s report lists the recalls FDA classified, and when.
