Zepbound helps adults with obesity lose weight and keep it off. It is proven to deliver significant and sustained weight loss.†‡
Zepbound is not for cosmetic weight loss.
†Along with diet and exercise.
‡In a 72-week study of adults without diabetes, average weight loss was 15.0% (34 lbs) for 5 mg, 19.5% (44 lbs) for 10 mg, 20.9% (48 lbs) for 15 mg, and 3.1% (7 lbs) for placebo. Average starting weights were 226.8 lbs for 5 mg, 233.3 lbs for 10 mg, 232.8 lbs for 15 mg, and 231.0 lbs for placebo. In a 72-week study of adults with diabetes, average weight loss was 12.8% (28 lbs) for 10 mg, 14.7% (33 lbs) for 15 mg, and 3.2% (7 lbs) for placebo. Average starting weights were 222.4 lbs for 10 mg, 219.6 lbs for 15 mg, and 224.2 lbs for placebo.
§Individual results may vary. In a 72-week study of adults without diabetes, the percent who saw ≥25% body weight loss (57-58 lbs):
- Zepbound 5 mg: 15.3%
- Zepbound 10 mg: 32.3%
- Zepbound 15 mg: 36.2%
- Placebo: 1.5%
Results are based on less-rigorous assessment and may be due to chance. Factors beyond Zepbound may have contributed to weight loss.
4-6x more weight loss with Zepboundǁ
than diet and exercise alone
In a 72 week study, weight loss was 15% for 5 mg dose, 20.9% for 15 mg dose compared to 3.1% for placebo

Average percent weight loss observed across different doses at 17 months
Overall change in body weight after 17 months* in adults without diabetes was a loss of 15.0% (34 lbs) for 5 mg, 19.5% (44 lbs) for 10 mg, 20.9% (48 lbs) for 15 mg, and 3.1% (7 lbs) for placebo.
Average starting weights were 226.8 lbs for 5 mg, 233.3 lbs for 10 mg, 232.8 lbs for 15 mg, and 231.0 lbs for placebo.
*Treatment or placebo included a reduced-calorie diet and increased physical activity.
Continued use of Zepbound MTD (10 mg or 15 mg) for significant weight loss vs placebo
In a study lasting 88 weeks, adults without diabetes were treated with increasing doses of Zepbound. On average, participants experienced weight loss after 36 weeks—the first phase of the study. Participants were then randomly assigned to either continue receiving Zepbound or switch to placebo. Those who stayed on Zepbound MTD (10 mg or 15 mg) continued losing weight while those who received placebo regained weight.

In a study lasting 88 weeks, adults without diabetes were treated with increasing doses of Zepbound for 36 weeks. On average, participants experienced weight loss during this first phase. Participants were then randomly assigned to either continue receiving Zepbound MTD for 52 weeks or switch to placebo. From week 36, those who continued to receive Zepbound had an average weight loss of 5.5% (10.3 lbs) while those who switched to placebo had an average weight regain of 14% (24.6 lbs). Average starting weight was 236.6 lbs.

bIndividual results may vary. An 88-week study examined adults without diabetes with obesity or overweight and weight-related medical problems. The average starting weight for these participants was 236.6 lbs. For the first 36 weeks, all participants received—and knew they were receiving—Zepbound MTD (10 mg or 15 mg, the max dose a participant could tolerate). Participants who finished this first phase lost an average of 20.9% of their body weight. This phase of the study was less rigorous and factors beyond Zepbound may have contributed to weight loss.
In the more rigorous phase of the study from weeks 36 to 88, participants who remained on Zepbound weighed 186.5 lbs at week 36, on average. They lost an average of 5.5% (10.3 lbs) of their body weight at week 88. Those who were switched to placebo weighed 189.2 lbs at week 36, on average. They gained back an average of 14% (24.6 lbs) body weight at week 88.

See how Zepbound compared to Wegovy® (semaglutide)¶**
People who took Zepbound MTD (10 mg or 15 mg) on average lost 50 lbs (20.2% weight loss) compared to people who took Wegovy MTD (1.7 mg or 2.4 mg) and on average lost 33 lbs (13.7% weight loss).
Individual results may vary.
Data collected in a less rigorous study so findings are less certain. Factors beyond studied medications may have contributed to weight loss.

**In a 72-week study of adults without diabetes with obesity or overweight and weight-related medical problems, participants on Zepbound MTD (10 mg or 15 mg, the max dose a participant could tolerate) experienced on average a 20.2% (50 Ibs) weight loss compared to an average of 13.7% (33 Ibs) weight loss for participants on Wegovy MTD (1.7 mg or 2.4 mg, the max dose a participant could tolerate). Average starting weights were 248.4 Ibs for Zepbound MTD and 250 Ibs for Wegovy MTD.

What is Zepbound?
Zepbound is an injectable prescription medicine that may help adults with obesity, or some adults with overweight who also have weight-related medical problems, to lose excess body weight and keep the weight off. Zepbound should be used with a reduced-calorie diet and increased physical activity.
- Zepbound contains tirzepatide and should not be used with other tirzepatide-containing products or any GLP-1 receptor agonist medicines.
- It is not known if Zepbound is safe and effective for use in children.
Finally, there’s Zepbound—the first and only weight loss treatment of its kind§§
§§Zepbound activates the receptors of 2 hormones: glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1).
Zepbound tackles an underlying cause of excess weight.
It reduces appetite and how much you eat.
