Wrong potency or content

Sub- or super-potent product, or a failed content-uniformity / assay test. You may receive too little or too much active ingredient - a direct dosing risk.

992 FDA drug recalls with this cause, newest first.

These recalls cover sub-potent or super-potent products, or a failed content-uniformity test - meaning some pills in the same batch held noticeably different amounts of active ingredient than others. Either way it is a direct dosing risk: too little to work, or too much and harmful. Thyroid hormones and compounded injectables are the classic examples, because their dose window is narrow.
