Ozempic Dose Calculator
Map your semaglutide titration from week 1 through the 2.4 mg maintenance dose. Enter your start date and see every dose step, refill window, and maintenance target in one schedule.
What Is the Ozempic Titration Schedule?
The Ozempic dose calculator turns the standard semaglutide titration schedule into a week-by-week plan. Semaglutide is started low and increased every four weeks to let the gut adjust, reducing nausea and vomiting. The schedule climbs from 0.25 mg weekly to a 2.4 mg maintenance dose by about week 17, the target used for chronic weight management.
How the Dose Steps Work
Standard titration follows five steps: 0.25 mg for weeks 1-4, 0.5 mg for weeks 5-8, 1.0 mg for weeks 9-12, 1.7 mg for weeks 13-16, and 2.4 mg from week 17 onward. Each step is a once-weekly subcutaneous injection in the abdomen, thigh, or upper arm. If side effects are severe, clinicians often hold a dose for an extra four weeks rather than advancing on schedule.
Refill and Pen Planning
Ozempic and Wegovy pens contain a fixed number of doses per strength. The calculator shows which week you move to the next pen strength so you can time pharmacy refills and avoid running out mid-titration. Insurance prior authorization often takes 5-10 business days, so request the next-strength pen at least two weeks before the switch week.
Important Safety Note
This calculator is informational only and is not medical advice. Semaglutide dosing varies by indication (type 2 diabetes vs chronic weight management), tolerability, and kidney function. Only a prescribing clinician can confirm your dose, schedule adjustments, and refill timing. Stop the medication and seek care for severe abdominal pain, persistent vomiting, or signs of pancreatitis.
Frequently Asked Questions
What is the standard Ozempic titration schedule?
For chronic weight management, the standard schedule is 0.25 mg weekly for weeks 1-4, then 0.5 mg weeks 5-8, 1.0 mg weeks 9-12, 1.7 mg weeks 13-16, and 2.4 mg from week 17 as the maintenance dose. For type 2 diabetes, most patients stop at 1.0-2.0 mg weekly depending on A1C response.
Can I stay on a lower dose instead of titrating up?
Yes, with clinician approval. If a lower dose is effective for your indication and tolerated well, many prescribers hold there. For weight management, clinical trials showed the strongest results at 2.4 mg, but some patients respond at 1.0-1.7 mg with fewer side effects.
What if I have severe nausea during titration?
Common practice is to hold the current dose for an additional four weeks rather than escalating, or step back down one level temporarily. Persistent vomiting, severe abdominal pain, or signs of pancreatitis require immediate medical attention and possibly stopping the medication.
When should I refill my pen for the next dose step?
Request the next-strength pen at least two weeks before your switch week. Insurance prior authorizations often take 5-10 business days, and specialty pharmacy shipping adds more time. Running out mid-titration forces a restart at a lower dose.
Is this calculator medical advice?
No. This tool is informational only and does not replace medical advice. Only your prescribing clinician can confirm the right dose, schedule, and adjustments for your specific situation, indication, and kidney function.
What is the difference between Ozempic and Wegovy dosing?
Both are semaglutide. Ozempic is labeled for type 2 diabetes with a 2.0 mg max weekly dose, while Wegovy is labeled for chronic weight management with a 2.4 mg maintenance dose. The titration steps in weeks 1-12 are essentially identical.
