From the Guidelines
When considering a Zepbound dose increase, it is recommended to increase the dose by 1–2 units or 10–15% twice weekly, as stated in the 2023 standards of care in diabetes 1. This approach allows for a gradual titration schedule, minimizing gastrointestinal side effects. The key considerations for dose increase include:
- Monitoring for weight loss progress, with an expected 5% weight reduction within 3 months of treatment
- Adjusting the dose or reevaluating the treatment approach if the target weight loss is not achieved
- Being aware of potential gastrointestinal side effects, such as nausea, vomiting, and diarrhea, and maintaining the current dose until symptoms improve before attempting further increases
- Considering the mechanism of action of Zepbound, which activates GLP-1 and GIP receptors to regulate blood glucose and reduce appetite Some studies have shown that GLP-1 receptor agonists, such as semaglutide, can achieve significant weight loss and improve weight-related comorbidities 1. However, the specific dosing and titration schedule for Zepbound should be based on the most recent and highest-quality evidence, which recommends a gradual increase of 1–2 units or 10–15% twice weekly 1. It is also important to note that the FDA indication for antiobesity medications, including Zepbound, is a BMI ≥ 30 kg/m² or BMI ≥ 27 kg/m² with significant complications, and that patients should be monitored for potential side effects and contraindications, such as pancreatitis and suicidal ideation and behavior 1.

2 DOSAGE AND ADMINISTRATION
- 2 Recommended Dosage Recommended Maintenance and Maximum Dosages for Glycemic Control The recommended maintenance dosage is 0.5 mg, 1 mg, or 2 mg, injected subcutaneously once weekly, based on glycemic control. If additional glycemic control is needed after at least 4 weeks on the: • 0. 5 mg dosage, the dosage may be increased to 1 mg once weekly. • 1 mg dosage, the dosage may be increased to 2 mg once weekly. The maximum recommended dosage is 2 mg once weekly.
The Zepbound dose increase considerations are as follows:
- The dosage may be increased to 1 mg once weekly if additional glycemic control is needed after at least 4 weeks on the 0.5 mg dosage.
- The dosage may be increased to 2 mg once weekly if additional glycemic control is needed after at least 4 weeks on the 1 mg dosage.
- The maximum recommended dosage is 2 mg once weekly 2. Key points to consider when increasing the dose:
- Glycemic control: Increase the dosage based on glycemic control.
- Timeframe: Wait at least 4 weeks before increasing the dosage.
- Maximum dosage: Do not exceed the maximum recommended dosage of 2 mg once weekly.
From the Research
Zepbound Dose Increase Considerations
- The provided studies do not directly address Zepbound dose increase considerations, but they do discuss the efficacy and safety of semaglutide, a glucagon-like peptide-1 receptor agonist, in patients with type 2 diabetes 3, 4, 5, 6, 7.
- Semaglutide has been shown to be effective in reducing HbA1c levels, body weight, and systolic blood pressure, with a favorable effect on cardiovascular outcomes 4, 5, 6, 7.
- The studies suggest that semaglutide is generally well-tolerated, with gastrointestinal adverse events being the most common side effect 3, 4, 7.
- There is no direct evidence to support specific dose increase considerations for Zepbound, but the studies provide information on the efficacy and safety of semaglutide at different doses 4, 5, 6, 7.
- For example, a study comparing oral semaglutide 14 mg with an injectable GLP-1RA, liraglutide 1.8 mg, or placebo found that treatment with oral semaglutide gave similar reductions in glycated hemoglobin (HbA1c) compared with liraglutide at 26 weeks, and significantly greater reductions at 52 weeks 4.
- Another study found that once-weekly semaglutide 1.0 mg performed significantly better than SGLT-2 inhibitors in reducing HbA1c levels and body weight in patients with type 2 diabetes inadequately controlled with metformin monotherapy 5.
