Mounjaro can be kept at room temperature (up to 86°F or 30°C) for a maximum of 21 days. If it accidentally reaches room temperature, this 21-day limit applies even if you return it to the refrigerator afterward. If Mounjaro has been unrefrigerated for more than 21 days, it should not be used.

Yes, Mounjaro should be stored in the refrigerator at a temperature between 36°F and 46°F (2°C to 8°C). Before use, it can be allowed to reach room temperature for a more comfortable injection. Once you've started using a pen, it can be stored at room temperature for up to 21 days. However, it's important not to freeze Mounjaro, as freezing can damage the medication.

When starting Mounjaro (tirzepatide) for the first time, the typical initial dosage is 2.5 mg, administered as a subcutaneous injection (under the skin) once a week. You can take this injection with or without food. After the first 4 weeks, your doctor will usually increase the dose to 5 mg once weekly for another 4 weeks, based on how you respond to the medication.

If you inject Mounjaro in a different spot than usual, it generally won’t affect how much of the medication your body absorbs. However, it's important to rotate your injection sites if you're using the same area of your body each week. This helps prevent skin irritation and ensures consistent absorption. Proper injection technique is crucial for receiving the full benefit of each dose.

If a needle hits a bone during an injection, it can cause immediate pain and swelling at the injection site. Although rare, deeper penetration might lead to more severe issues, such as a bone fracture or a periosteal reaction (inflammation of the tissue surrounding the bone). To minimize risks, it's important to use proper injection techniques and choose appropriate needle lengths based on the patient's body composition and the injection site.

It is not recommended to combine multiple doses of Mounjaro (tirzepatide) into a single injection. Each dose should be administered as prescribed by your healthcare provider, following the guidelines provided in the prescribing information. Always refer to the safety information, including any boxed warnings, that accompany your medication for specific instructions and precautions.
