What Is Zepbound?
Zepbound is the brand name for tirzepatide, a once-weekly injectable medication manufactured by Eli Lilly.
It belongs to a class of medicines known as GIP and GLP-1 receptor agonists. Zepbound works on hormone pathways involved in appetite and food intake. The FDA-approved prescribing information states that Zepbound is used together with a reduced-calorie diet and increased physical activity.
Zepbound is approved for chronic weight management in eligible adults and for the treatment of moderate-to-severe obstructive sleep apnea in adults with obesity.
What Is Zepbound Used For?
Zepbound is approved for:
- Reducing excess body weight and maintaining weight reduction long-term in adults with obesity
- Reducing excess body weight and maintaining weight reduction long-term in certain adults who are overweight and have at least one weight-related medical condition
- Treating moderate-to-severe obstructive sleep apnea in adults with obesity
Zepbound should be used alongside a reduced-calorie diet and increased physical activity.
Whether Zepbound is appropriate depends on an individual’s medical history, current medications, health conditions, and other factors. A healthcare professional should determine whether treatment is appropriate.
Zepbound Dosage
Zepbound is injected once weekly. The FDA-approved prescribing information recommends starting with 2.5 mg once weekly for four weeks. The dosage may then be increased in 2.5 mg increments after at least four weeks on the current dose, depending on treatment response and tolerability.
