Do I need to have a caregiver administer my Mounjaro injections?
No, but it depends on where you inject the drug.

If you need help administering your Mounjaro injections, talk with your doctor or pharmacist.
Can I bring Mounjaro with me on vacation?

According to the drug’s manufacturer, Mounjaro can be kept out of the refrigerator for up to 21 days. You should keep Mounjaro pens in their original container and away from light. The drug should not be stored in a place where the temperature is higher than 86°F (30°C).
If you plan to bring Mounjaro with you on an airplane, be sure to find out if there are specific rules you need to follow for the airline. Their guidelines may differ depending on your destination.
If I improve my diet and exercise routine, will my Mounjaro dosage be lowered?
It depends. Mounjaro is meant to be taken in combination with a balanced diet and exercise.
If your diet and exercise routines improve, you’re likely to have better health outcomes, including:
- steadier blood sugar levels
- lower A1C, which measures your average blood sugar over a certain length of time
- reduced risk of long-term cardiovascular problems
Diet, exercise, and Mounjaro work together to help manage blood sugar levels in people with type 2 diabetes. That said, your doctor will likely monitor your blood sugar and A1C levels periodically during your Mounjaro treatment. They’ll determine the right dosage for you based on your test results.
Talk with your doctor if you think you might need your Mounjaro dosage changed.
