Medically reviewed by Last updated on Dec 5, 2019.

Generic name: lanadelumab 300mg in 2mL
Dosage form: injection, solution


The recommended starting dose is 300 mg every 2 weeks. A dosing interval of 300 mg every 4 weeks is also effective and may be considered if the patient is well-controlled (e.g., attack free) for more than 6 months.


TAKHZYRO is administered subcutaneously only.

TAKHZYRO is provided as a ready-to-use solution in a single-dose vial that does not require additional reconstitution or dilution for administration. TAKHZYRO is supplied as a clear to slightly opalescent, colorless to slightly yellow solution. Do not use the vial if it appears discolored or contains visible particles. Avoid vigorous agitation of the vial.

TAKHZYRO is intended for self-administration or administration by a caregiver. The patient or caregiver should be trained by a healthcare professional.

Take the TAKHZYRO vial out of the refrigerator 15 minutes before injecting to allow it to equilibrate to room temperature.

Using aseptic technique, withdraw the prescribed dose of TAKHZYRO from the vial using an 18-gauge needle. Change the needle on the syringe to a 27-gauge, ½-inch needle or other needle suitable for subcutaneous injection. Inject TAKHZYRO subcutaneously into the abdomen, thigh, or upper arm. Patients should inject the complete dose as prescribed by their physician. In clinical studies, the majority of patients self-administered TAKHZYRO over 10 to 60 seconds.

TAKHZYRO should be administered within 2 hours of preparing the dosing syringe. After the dosing syringe is prepared, it can be refrigerated at 36ºF to 46ºF (2°C to 8°C) and must be used within 8 hours.

Discard any unused portions of drug remaining in the vial and syringe.
