2.6 Administration Instructions for ILARIS Injection

STEP 1: ILARIS injection has a concentration of 150 mg/mL. Do not shake. The solution should be essentially free from particulates, clear to opalescent, colorless to slightly brownish-yellow tint. If the solution has a distinctly brown discoloration, is highly opalescent or contains visible particles, do not use.

STEP 2: Using a sterile 1-mL syringe and 18-gauge x 2” needle, carefully withdraw the required volume depending on the dose to be administered and subcutaneously inject using a 27-gauge x 0.5” needle.

Avoid injection into scar tissue as this may result in insufficient exposure to ILARIS.

Discard unused product or waste material in accordance with the local requirements.
