The MHRA (Medicines and Healthcare products Regulatory Agency) has extended the expiry dates of certain batches of Mounjaro. This practice is common with newer medications. Initially, they undergo testing to ensure they are safe for distribution, and manufacturers continue to test them over time.

Even if the expiry date printed on your pen is listed as expired, it may still be safe to use.

You can read the full letter, including the batches affected and the extension of the expiry attached below.

We include a printed version of this letter in all of our affected orders, and also include it in your dispatch email.
