Important safety information. This page is general education, not medical advice. Only a licensed clinician who knows your history can decide whether a medication is right for you. Do not start, stop or change a prescription without talking to your clinician. If you have severe abdominal pain, trouble breathing, swelling of the face or throat, or thoughts of harming yourself, seek emergency care or call 988.
What It Is
Zepbound is a weekly injection that reduces appetite and food intake by activating both GIP and GLP-1 receptors.
FDA-Approved Uses
Zepbound is approved, with diet and exercise, for long-term weight management in adults with obesity (BMI 30 or higher) or overweight (BMI 27 or higher) with a weight-related condition, and for moderate-to-severe obstructive sleep apnea in adults with obesity.
How It Is Taken
Dosing starts at 2.5 mg once weekly for 4 weeks, then increases in 2.5 mg steps every 4 weeks as tolerated. Maintenance doses are 5, 10 or 15 mg.
What to Expect
In the SURMOUNT-1 trial, adults on the 15 mg dose lost an average of about 21% of body weight over 72 weeks, compared with about 3% on placebo. Lower doses produced less weight loss, and results vary.
Common Side Effects
Nausea, diarrhea, vomiting, constipation, stomach pain, indigestion and injection-site reactions.
Serious Warnings
The label carries a boxed warning for thyroid C-cell tumors seen in animals; it is not for people with a personal or family history of medullary thyroid carcinoma or MEN 2. Other warnings include pancreatitis, gallbladder disease, dehydration and kidney injury, low blood sugar with insulin or sulfonylureas, diabetic retinopathy changes, mood changes, and aspiration risk during anesthesia. Tirzepatide can make oral birth control less effective, so a non-oral or added barrier method is advised for 4 weeks after starting and after each dose increase.
Frequently Asked Questions
Is Zepbound the same as Mounjaro?
Both contain tirzepatide. Zepbound is approved for weight management and sleep apnea; Mounjaro is approved for type 2 diabetes.
How is tirzepatide different from semaglutide?
Tirzepatide acts on two hormone pathways; semaglutide acts on one. Your clinician can help compare them for your situation.
Does it affect birth control?
It can reduce the effectiveness of oral birth control pills. Ask your clinician about backup methods.
