ZILBRYSQ may cause serious side effects, including inflammation of the pancreas (pancreatitis) and other pancreatic problems.
Call your healthcare provider right away if you have pain in your stomach area (abdomen) that will not go away. Your healthcare provider will tell you if you should stop using ZILBRYSQ. The pain may be severe or felt going from your abdomen to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis.
The most common side effects of ZILBRYSQ include:
- injection site reactions
- upper respiratory tract infections
- diarrhea
Tell your healthcare provider about any side effect that bothers you or that does not go away. These are not all the possible side effects of ZILBRYSQ. You may report side effects to FDA at 1-800-FDA-1088.
