Preparation

Vial preparation instructions

• Allow refrigerated QALSODY vial to warm to room temperature (25°C/77°F) prior to administration without using external heat sources.
• Inspect the solution in the QALSODY vial prior to administration. Do not administer if particles are observed or the liquid in the vial is not clear and colorless to slightly yellow.
• Do not shake the QALSODY vial.

Procedural preparation instructions

• If indicated by the clinical condition of the patient, consider sedation.
• If indicated by the clinical condition of the patient, consider imaging to guide intrathecal administration of QALSODY.
• Prior to removing the vial's cap on the aluminum overseal, confirm readiness of the patient. An unopened QALSODY vial can be returned to the refrigerator.
• Evaluate patients prior to and after intrathecal injection for the presence of potential conditions related to lumbar puncture, to avoid serious procedural complications.

Administration

Prior to administration, remove approximately 10 mL of cerebrospinal spinal fluid (CSF) using a lumbar puncture needle.

Prior to administration, remove the plastic cap and attach a needle to the syringe, for the purpose of withdrawing QALSODY from the vial. Insert the needle into the vial through the center of the overseal and withdraw the required dose of 15 mL (equivalent to 100 mg) from the vial.

• Do not dilute QALSODY.
• External filters are not required.

Administer QALSODY using a lumbar puncture needle as an intrathecal bolus injection over 1 to 3 minutes.

• QALSODY contains no preservatives. Once drawn into the syringe, the solution should be administered immediately (within 4 hours of removal from the vial) at room temperature; otherwise, it must be discarded.

Any unused contents of the single-dose vial should be discarded.
