What happens if you miss a dose?
If you miss a dose of Mounjaro, what you should do depends on how much time has passed since your scheduled injection.
If it’s been 4 days (96 hours) or less since your missed dose: Take your missed dose as soon as possible, then continue with your usual weekly injection schedule.
If it’s been more than 4 days (96 hours) since your missed dose: Skip the missed dose and take your next dose on your usual scheduled day.
Always leave at least 3 days (72 hours) between Mounjaro injections. Never take two doses at the same time to make up for a missed dose.
If you’re unsure what to do, speak to your prescriber or pharmacist.
What foods can't you eat?
Mounjaro doesn’t stop you from eating any foods (unless you’re allergic or intolerant).
However, you may want to avoid foods with a strong smell or taste, if you experience nausea.
Mounjaro is most effective when coupled with lifestyle changes, so you may also benefit from changing your diet towards eating less fats or fatty foods.
