Maximum Weekly Dose of Ozempic (Semaglutide)
The maximum recommended weekly dose of Ozempic (semaglutide) for glycemic control is 1 mg administered subcutaneously once weekly. 1
Dosing Schedule and Titration
Ozempic follows a specific dose escalation protocol to minimize gastrointestinal side effects:
- Start with 0.25 mg subcutaneously once weekly for 4 weeks (initiation dose, not effective for glycemic control)
- After 4 weeks, increase to 0.5 mg once weekly
- If additional glycemic control is needed after at least 4 weeks on the 0.5 mg dose, the dosage may be increased to the maximum dose of 1 mg once weekly 1
Evidence Supporting Maximum Dose
The FDA-approved drug label clearly establishes 1 mg as the maximum weekly dose for Ozempic when used for glycemic control in type 2 diabetes 1. This is consistent with clinical guidelines from the American College of Cardiology, which indicate that semaglutide should be initiated at 0.25 mg weekly, then titrated to 0.5 mg, and finally to 1 mg weekly as the maximum dose for glycemic control 2.
Multiple clinical trials in the SUSTAIN program have demonstrated the efficacy and safety of semaglutide at the 1 mg weekly dose 3, 4, 5. A recent retrospective cohort study also confirmed the effectiveness of both 0.5 mg and 1 mg doses in real-world practice 6.
Important Clinical Considerations
- Administration timing: Administer Ozempic once weekly, on the same day each week, at any time of day, with or without meals 1
- Missed doses: If a dose is missed, administer as soon as possible within 5 days; if more than 5 days have passed, skip the missed dose and resume regular schedule 1
- Renal function: No dose adjustment is required for patients with renal impairment 2
- Common side effects: Nausea, vomiting, diarrhea, abdominal pain, and constipation are common, particularly during dose escalation 2
Special Populations and Weight Management
It's important to note that while 1 mg is the maximum weekly dose for glycemic control in type 2 diabetes, higher doses of semaglutide (2.4 mg weekly) are approved for weight management under the brand name Wegovy 2. However, Ozempic is specifically FDA-approved for glycemic control with a maximum dose of 1 mg weekly.
Potential Pitfalls
- Rapid titration: Increasing the dose too quickly can lead to increased gastrointestinal side effects and potential discontinuation of therapy
- Exceeding maximum dose: Using doses higher than 1 mg weekly of Ozempic for diabetes treatment is off-label and not supported by the FDA approval
- Perioperative considerations: Recent evidence suggests increased risk of aspiration during anesthesia in patients taking GLP-1 receptor agonists, even with prolonged fasting 2
Remember that the maximum dose of 1 mg weekly should only be reached after appropriate titration and if needed for adequate glycemic control.
