NUCALA should be reconstituted by a healthcare professional. The reconstituted solution will contain a concentration of 100 mg/mL mepolizumab. Do not mix with other medications.
Ensure you have everything you need to reconstitute NUCALA:
Withdraw: 1.2 mL of Sterile Water for Injection into the syringe.
Direct: the stream of Sterile Water for Injection vertically onto the center of the lyophilized cake.
Gently swirl the vial for 10 seconds with circular motion at 15-second intervals until the powder is dissolved.*
DO NOT SHAKE the reconstituted solution during the procedure because this may lead to product foaming or precipitation.
INSPECT the reconstituted solution. If particulate matter remains in the solution or if it appears cloudy or milky, the solution must not be administered.†
Manual reconstitution is typically complete ~5 minutes after the water has been added.
* If a mechanical reconstitution device (swirler) is used to reconstitute NUCALA, swirl at 450 rpm for no longer than 10 minutes. Alternatively, swirling at 1000 rpm for no longer than 5 minutes is acceptable.
† The solution should be clear to opalescent, and colorless to pale yellow or pale brown, essentially particle free. Small air bubbles, however, are expected and acceptable.
