How It Works

Wegovy follows a fixed dose escalation schedule to minimise gastrointestinal side effects. You start at 0.25mg weekly for 4 weeks, then increase to 0.5mg, 1mg, 1.7mg, and finally 2.4mg, each step lasting 4 weeks. The calculator takes your start date and maps out the exact dates for each dose change. Your prescribing doctor will confirm the schedule.

Frequently Asked Questions

What is the Wegovy dose schedule?
Wegovy uses a 5-step dose escalation: 0.25mg (weeks 1-4), 0.5mg (weeks 5-8), 1mg (weeks 9-12), 1.7mg (weeks 13-16), and 2.4mg (week 17 onward as maintenance). Each dose is injected once weekly. The gradual increase helps reduce nausea and other GI side effects.
Is Wegovy available in Australia?
Wegovy (semaglutide 2.4mg) was approved by the TGA for chronic weight management in Australia. Availability may vary and it requires a prescription from a doctor. It is indicated for adults with a BMI of 30+ or 27+ with weight-related comorbidities.
What happens if I miss a Wegovy dose?
If you miss a dose and your next scheduled dose is more than 2 days away, take the missed dose as soon as possible. If the next dose is less than 2 days away, skip the missed dose and take the next one on schedule. Do not take two doses to make up for a missed one. Contact your doctor if you miss multiple doses.

In clinical trials (STEP program), participants lost an average of 15-17% of their body weight over 68 weeks on Wegovy combined with lifestyle changes. Individual results vary significantly. Weight loss is gradual, with most occurring in the first 6-9 months of treatment.
