How to take your Mounjaro dose
Mounjaro comes in the form of an injectable pen, with pre-filled doses. This means you don’t need to draw up your dose before injecting it. You should take Mounjaro once weekly, at the same time and day. This makes the medication most effective and can reduce side effects by keeping the medication at a steady level.
The Mounjaro ‘KwikPen’ is a single-patient-use pen that contains 4 fixed doses, with 1 dose injected each week. That means 1 pen provides 4 weeks of treatment. Once all 4 doses have been used, you can throw the pen away.
Mounjaro can be injected into the abdomen. It may also be injected into the upper arms but only with help from someone else. Switch your injection site each week to prevent soreness and irritation.
Your used Mounjaro pen can be stored at room temperature, up to 30 degrees Celsius (°C), for no more than 30 days. Keep it away from direct light and in its original packaging. You can also store it in a fridge between 2 and 8°C and if you choose this method, it does not need to be discarded after 30 days.
