TIPS FOR USING STRENSIQ
You probably have some questions about fitting STRENSIQ® (asfotase alfa) into your routine. If you’re looking for more information, don’t hesitate to talk to your doctor or reach out to OneSource™.
HOW TO STORE STRENSIQ
Since STRENSIQ is a sensitive enzyme, it is important to store and handle it correctly.


Remember that STRENSIQ comes in single-use vials, so throw away any extra STRENSIQ left in the vial after your injection.
TRAVELING WITH STRENSIQ
When traveling with STRENSIQ, keep it refrigerated throughout your trip in its original package at 36°F to 46°F (2° to 8°C). Before you head out on your next getaway, consider the following ideas:
Plan ahead
Gather your injection supplies and check with your destination to make sure there will be a place to refrigerate STRENSIQ when you get there.
Keep cool
To maintain its ideal temperature, STRENSIQ may be stored in an insulated cooler with ice or an ice pack. If traveling long distances by plane, call ahead to your airline to find out if refrigeration is provided in-flight or if attendants can provide additional ice.
Planning a trip? Once prescribed, you will receive an injection starter kit that includes a travel letter that can be shown to airline staff to make sure your STRENSIQ is handled with care. You can also download a travel letter here.

Strensiq may affect other lab test results, therefore it is important that you present your Medical Alert Card to your healthcare team so they are aware that you are being treated with an alkaline phosphatase (ALP) replacement therapy which may cause incorrect results on certain laboratory tests.
