If you miss a dose
- Mounjaro and Zepbound: take it as soon as possible within 4 days (96 hours). If more than 4 days have passed, skip it and take the next dose on your usual day.
- After two or more missed doses in a row, the Wegovy label says you may need to restart the step-up. Ask your prescriber what to do with any of these medicines.
Four weeks is a minimum
For Ozempic, Mounjaro and Zepbound the labels say to step up after at least four weeks on the current dose, and your prescriber may keep you on a dose for longer or decide you don't need a higher one. Wegovy's label sets the steps out by week, but suggests delaying an increase by four weeks if a dose isn't tolerated. Never change your dose without talking to your prescriber.

Frequently asked questions
How does the Mounjaro dose go up?
2.5 mg once a week for 4 weeks, then 5 mg. After at least 4 weeks on each dose it can go up by 2.5 mg at a time, to 7.5, 10, 12.5 and at most 15 mg.
Is Zepbound dosed the same as Mounjaro?
The step-up is the same: 2.5 mg for 4 weeks, then 5 mg, rising by 2.5 mg after at least 4 weeks on each dose up to 15 mg. For weight reduction the label lists 5, 10 or 15 mg as maintenance doses.
Can I stay on a lower dose?
Yes, if your prescriber agrees. The step-ups are a minimum pace, and the labels say to consider response and tolerability when choosing the maintenance dose. The starting doses are not maintenance doses.
What if I miss a dose?
Mounjaro and Zepbound: within 4 days. Ozempic: within 5 days. Wegovy: only if the next dose is more than 2 days away. Otherwise skip it and keep your usual injection day.
