Every line below is in FDA’s own words, with its source beside it. FDA’s terms are explained in FDA’s own words.
How serious is it, by FDA’s class?
Class I, the most serious of FDA’s three classes.
“Dangerous or defective products that predictably could cause serious health problems or death. Examples include: food found to contain botulinum toxin, food with undeclared allergens, a label mix-up on a lifesaving drug, or a defective artificial heart valve.”
openFDA, in plain words, its enforcement report fields.
“Class I is a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death.”
FDA’s rule, 21 CFR 7.3(m)(1), eCFR.
What these words mean is quoted from openFDA’s field reference and 21 CFR 7.3.
What’s wrong with it?
Labeling: Label Mix-Up; Bottles of Mucinex Fast-Max liquid are correctly labeled on the front of the label, however the back of the bottle where the Drug Facts labeling is, is missing certain Active Ingredients such as acetaminophen, phenylephrine, dextromethorphan, diphenhydramine, and/or guaifenesin. As a result certain safety warnings associated with those ingredients may also be missing.

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.
