Only LEQEMBI empowers patients with
maintenance dosing options to help them
continue their treatment journey1,2

A baseline MRI is required to initiate treatment.1

*10 mg/kg once every 4 weeks. Patients may also continue with 10 mg/kg twice-monthly infusion dosing after 18 months.1

Patients who continue on therapy beyond 18 months may be able to maintain treatment benefits for longer1

If transitioning from starting dosage to a maintenance dosage regimen, administer the first maintenance dose 2 weeks after the last starting dose.1

LEQEMBI vials
  • Confirm the presence of Aβ pathology prior to initiating treatment
  • After each infusion, ensure the patient/care partner has confirmed an appointment for their next infusion
  • During maintenance dosage regimen, patients may switch the route of administration (intravenous LEQEMBI or subcutaneous LEQEMBI IQLIK). This transition should be initiated at 1 week following the last maintenance dose of either the intravenous or subcutaneous dosing regimen. Thereafter, follow the dosing schedule for the newly assigned maintenance dosage regimen

IV Administration1

  • Visually inspect the LEQEMBI diluted solution for particles or discoloration prior to administration. Do not use if it is discolored, or opaque, or foreign particles are seen

  • Prior to infusion, allow the LEQEMBI diluted solution to warm to room temperature

  • Infuse the entire volume of LEQEMBI diluted solution intravenously over approximately 1 hour through an IV line containing a terminal low-protein binding 0.2 micron in-line filter. Flush infusion line to ensure all LEQEMBI is administered

  • Monitor for any signs or symptoms of an infusion-related reaction. The infusion rate may be reduced, or the infusion may be discontinued, and appropriate therapy administered as clinically indicated. Consider pre-medication at subsequent dosing with antihistamines, non-steroidal anti-inflammatory drugs, or corticosteroids

  • If a starting dosage or maintenance dosage infusion is missed, administer the next dose as soon as possible

  • After each infusion, ensure the patient/care partner has confirmed an appointment for their next infusion

  • See dosing calculator below.
