NUCALA should be reconstituted and administered by a healthcare professional.
Once-monthly fixed dose
- 100 mg administered by subcutaneous (SC) injection once every 4 weeks
An instructional video on reconstitution can be found at www.NucalaPrep.com
- Reconstitute NUCALA in the vial with 1.2 mL Sterile Water for Injection, USP, preferably using a 2- or 3-mL syringe and a 21-G needle. The reconstituted solution will contain a concentration of 100 mg/mL mepolizumab. Do not mix with other medications.
- Direct the stream of Sterile Water for Injection vertically onto the center of the lyophilized cake. Gently swirl the vial for 10 seconds with a circular motion at 15-second intervals until the powder is dissolved.
- If a mechanical reconstitution device (swirler) is used to reconstitute NUCALA, swirl at 450 rpm for no longer than 10 minutes. Alternatively, swirling at 1,000 rpm for no longer than 5 minutes is acceptable.
- Visually inspect the reconstituted solution for particulate matter and clarity before use. 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. If particulate matter remains in the solution or if the solution appears cloudy or milky, the solution must not be administered.
- If the reconstituted solution is not used immediately:
- store below 30°C (86°F),
- do not freeze, and
- discard if not used within 8 hours of reconstitution.
- For subcutaneous administration, preferably using a 1-mL polypropylene syringe fitted with a disposable 21- to 27-G x 0.5-inch (13-mm) needle.
- Just before administration, remove 1 mL of reconstituted NUCALA. Do not shake the reconstituted solution during the procedure as this could lead to product foaming or precipitation.
- Administer the 1-mL injection (equivalent to 100 mg mepolizumab) subcutaneously into the upper arm, thigh, or abdomen.
