Reporting Adverse Drug Events
Our ultimate goal is to create safe, effective products for everyone. If you experience an adverse event from one of our drugs, tell your healthcare provider and then report it to us. This helps us track the safety of our medicines accurately.
Patients should always ask their healthcare provider for medical advice about adverse events.
If you are participating in a clinical trial, please report the adverse event to your coordinating study site.
