Key Evidence
The FDA announced approval of Zepbound for chronic weight management on November 8, 2023.

What the Evidence Shows
The U.S. Food and Drug Administration approved Zepbound (tirzepatide) for chronic weight management on November 8, 2023. The approval applies to adults with obesity, defined in the FDA announcement as a BMI of 30 kilograms per square meter or greater.

The claim accurately states the date, drug, manufacturer, active ingredient and BMI threshold for the obesity indication. The full indication is broader than the claim suggests: Zepbound is also approved for adults who are overweight, with a BMI of at least 27, when they have at least one weight-related medical condition. Treatment is intended to be used alongside a reduced-calorie diet and increased physical activity. The omitted indication does not make the narrower statement that adults with a BMI of 30 or greater were covered by the approval inaccurate.accessdata.fda.govaccessdata.fda.govZEPBOUND (tirzepatide) injection, for subcutaneous use

The later 2026 label and PharmExec summary describe the same approved population and do not conflict with the contemporaneous November 2023 FDA and Eli Lilly records.
