From the Research
Mounjaro (tirzepatide) pens should be kept at room temperature for no more than 21 days after removing them from refrigeration, as stated in the example answer, but none of the provided studies directly address the storage duration of Mounjaro at room temperature. The storage instructions for Mounjaro are not explicitly mentioned in the provided studies 2, 3, 4, 5, 6. However, based on general guidelines for similar medications and the example answer, it is recommended to:
- Keep Mounjaro pens at room temperature for no more than 21 days after removing them from refrigeration
- Write down the date when a pen is taken out of the refrigerator to track the 21-day limit
- Store Mounjaro in the refrigerator at 36°F to 46°F (2°C to 8°C) in its original packaging to protect it from light before the 21-day period
- Never freeze Mounjaro pens, and avoid exposing them to extreme heat or direct sunlight, as these conditions can damage the medication and reduce its effectiveness. The provided studies focus on the efficacy and safety of tirzepatide for the treatment of obesity and diabetes 3, 4, its comparison with other medications 3, 6, and trends in its utilization 5, but do not provide specific guidance on storage duration at room temperature.
