We encourage healthcare professionals, patients and caregivers to report any side effects or problems with your Lilly medicine to help us ensure our products remain safe and effective. If you experience a side effect while using a Lilly product (medicine or device), you should always seek medical advice from your doctor.

If you live in the United States and have concerns about a possible side effect (safety of a Lilly medicine) or a product concern (the quality, usability, or appearance), please share your experience using one of the options below.

Once successfully submitted, you will receive a confirmation, which lets you know that we have received your information.

Due to high volumes, it may take some time for us to evaluate each report. Please note that we will only reach out to you if we need any further information. If we have all needed information, you will not be contacted by us.

Please do not call to follow up on your submission; this will not speed up the process and may delay our ability to process your submission efficiently. If you have a new side effect or quality concern, please submit a new report.
