Zepbound vs. Mounjaro: How do they compare?
Zepbound is one brand name of the medication tirzepatide. Zepbound is FDA-approved for the treatment of overweight and obesity while the other brand name of tirzepatide, Mounjaro, is FDA-approved for the treatment of type 2 diabetes. Despite their different names and different FDA-approved indications, the active ingredients and available dosages will be the same.
The FDA’s approval of tirzepatide under the brand name Zepbound for weight loss comes on the heels of the SURMOUNT-1 trial. During this trial, which was sponsored by the drug’s manufacturer, Eli Lilly, participants were given weekly doses of tirzepatide for 72 weeks. Participants on the highest dosage evaluated during the study lost an average of 20% of their body weight, meaning that this medication may be more effective than other similar medications that are currently available, like Wegovy.
Zepbound Availability, Dosage, and Cost
According to Eli Lilly, Zepbound is expected to be available in the U.S. by the end of 2023, and the list price will be $1,059.87 for a month’s supply. In comparison, the list price for Mounjaro is $1,023.04 for a month’s supply, so Zepbound is only slightly more expensive. Those who are commercially insured may be able to pay as little as $25 for a 1-month or 3-month prescription, depending on insurance coverage. Eli Lily also announced that if your insurance doesn’t cover Zepbound, you may be eligible to pay as little as $550 per month, roughly 50% less than the list price.
Zepbound will be available in six different doses, the same strengths as Mounjaro: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg.
If you’re interested in getting treatment with Zepbound, speak with a licensed healthcare professional who can evaluate your medical history and determine if Zepbound or another weight loss medication might be right for you.
