Take Mounjaro once a week
Pick your day.
Use Mounjaro 1 time each week, at any time of the day.
But we know schedules can change. If you want to change the day of the week you take your dose, make sure there are at least 3 days (72 hours) between doses.
If you miss a dose of Mounjaro, take the missed dose as soon as possible within 4 days (96 hours) after the missed dose. If more than 4 days have passed, skip the missed dose and take your next dose on the regularly scheduled day. Do not take 2 doses of Mounjaro within 3 days of each other.
It may be helpful to set a reminder in your phone so you don't forget which day is your Mounjaro day. If you set a reminder and decide to change your day, then don't forget to update your reminder to your new day.
Mounjaro comes in a single-dose pen that requires no mixing.
There is no need to see or handle the needle.†
