How the doses step up

Slowly, each starting on a low dose for 4 weeks. Mounjaro and Zepbound start at 2.5mg a week for 4 weeks, then 5mg, and may go up in 2.5mg steps, at least 4 weeks on each, to as much as 15mg. Wegovy starts at 0.25mg and rises every 4 weeks to 2.4mg from week 17. Your prescriber decides each step.

Worth knowing

    Your doctor may go higher if needed, Mounjaro’s says. Zepbound’s weight maintenance doses: 5, 10 or 15mg.

  • Your doctor’s call

    Mounjaro’s and Ozempic’s leaflets say not to change your dose unless your doctor has told you to do so.
