Why it was recalled

Cause type: Failed specification

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. All failed specification recalls.

D-0087-2024 · FDA notice

Check, then ask. Class II means harm is possible but usually temporary or reversible. Find the lot number on your package; if it matches, ask your pharmacist about a replacement. Do not simply stop a prescribed medication on your own - the gap can be riskier than the recall. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
