What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: FDA Class II drug recall for failed stability specifications with no reported illnesses or injuries. Stability failures represent a substantive quality/efficacy risk where the product may not maintain its labeled potency; this constitutes theoretical harm per the rubric, placing it at High (3) rather than Moderate.
