Companies usually start a recall weeks before the FDA classifies and publishes it; the gap above is that lag.

Reason for recall

CGMP Deviations: manufactured under the same conditions as those found to be subpotent.

Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
