How long can Xolair be kept (shelf life/expiration)?
Xolair (omalizumab) shelf life depends on the specific presentation (vial or prefilled syringe) and how the product is stored before use. Expiration dating is printed on the outer carton and the container label, and dosing should use only product that has not passed that date.
Because shelf-life rules can vary by formulation and storage conditions, the most accurate source for the exact time window for your specific Xolair product is the prescribing information/label for that exact package.
What storage conditions affect Xolair shelf life?
Xolair must be stored as directed on the label. Storage conditions (temperature and whether it has been left out of refrigeration) can shorten usable life even if the printed expiration date has not passed. If a dose has been kept outside the recommended conditions, follow the label guidance or ask the pharmacist/clinic for the correct handling instructions.
Can patients use Xolair after the expiration date?
No. Once Xolair is past its labeled expiration date, it should not be used. If you have product that is expired or may have been stored incorrectly, the clinic/pharmacy can advise whether it must be discarded.
Where to check the exact expiration/shelf-life details for your box?
Look for the expiration date and storage instructions printed on the carton and container label.

What if you tell me the form and strength?
If you share whether your Xolair is a vial or a prefilled syringe (and the strength listed on the label), I can narrow down which labeled shelf-life/expiration guidance applies to that specific product presentation.
