The FDA approved labeling updates for the OTC weight loss medication alli (orlistat) 60 mg capsules to include warnings regarding the risk of acute kidney injury and kidney stones. The new label instructs consumers to consult a healthcare provider before use.

Who it affects

This affects the manufacturer of alli (orlistat 60 mg), regulatory professionals responsible for OTC labeling compliance, and pharmacovigilance teams monitoring adverse events related to weight loss medications.
