17 PATIENT COUNSELING INFORMATION
Advise patients to:
- read the FDA-approved patient labeling (Patient Information and Instructions for Use).
- report any adverse reactions or problems that concern them when taking XYNTHA to their healthcare provider.
- discontinue use of the product, call their healthcare provider, and go to the emergency department if any allergic-type hypersensitivity reactions occur. Inform patients of the early signs of hypersensitivity reactions (including hives [rash with itching]), generalized urticaria, tightness of the chest, wheezing, hypotension) and anaphylaxis.
- contact their healthcare provider if they experience a lack of a clinical response to factor VIII replacement therapy, as this may be a manifestation of an inhibitor.
- notify their healthcare provider if they become pregnant or intend to become pregnant during therapy, or if they are breastfeeding.

Do not freeze.
Protect from light.
XYNTHA can last at room temperature (below 77°F) for up to 3 months. If you store XYNTHA at room temperature, carefully write down the date you put XYNTHA at room temperature, so you will know when to either put it back in the refrigerator, use it immediately, or throw it away. There is a space on the carton for you to write the date.
If stored at room temperature, XYNTHA can be returned one time to the refrigerator until the expiration date. Do not store at room temperature and return it to the refrigerator more than once. Throw away any unused XYNTHA after the expiration date.
