Other failed specifications

A physical or chemical test other than potency, dissolution, impurity or stability failed - pH, viscosity, appearance, tablet integrity, fill volume. A product outside its own specification may not perform as designed, even if the active ingredient is present.

394 FDA drug recalls with this cause, newest first.

Every drug has a specification sheet: pH, viscosity, moisture, tablet hardness, colour, fill volume, disintegration time. A lot that misses any of them is out of specification, even when the active ingredient is present in the right amount. These recalls include discoloured tablets, crystals forming in a solution, capsules that split, and short-filled containers. They are rarely Class I, but they signal a process that has drifted.
