IMAAVY infusion process

How IMAAVY is taken

At your first infusion appointment, your healthcare provider will give you a starting dose of
intravenous (IV)
IMAAVY, lasting at least 30 minutes. An IV infusion is given through a needle placed into your vein.

Two weeks later you will receive your next dose of IMAAVY infusion lasting at least 15 minutes. Your following doses will be given every 2 weeks.

After each dose of IMAAVY, your healthcare provider will monitor you for 30 minutes to look for any signs or symptoms of an infusion-related or hypersensitivity reaction.*

Allergic reactions can happen during your IMAAVY infusion. Tell your healthcare provider right away if you get any of these symptoms during your IMAAVY infusion.

*If you have a reaction during your IMAAVY infusion, your healthcare provider may decide to administer IMAAVY more slowly or stop your infusion. If you miss a scheduled IMAAVY infusion, you should receive your next dose as soon as possible.

I like the dosing schedule for IMAAVY because it’s consistent and it allows me to be able to plan my life around that consistency.
