Be the first to react

Bob, I was sitting in the chair yesterday waiting to get my fourth dose of Imaavy and realized I didn't have double vision anymore. Yay! I had a little trouble this morning, but it cleared up in a couple hours. I think my brain may be used to double vision and is adjusting to going back. Still impressed with my results. I hope they keep up. I would recommend it as a treatment. First dose is a little longer but after that you go in and take some Tylenol and Benadryl and wait half an hour for it to kick in to reduce any headaches from the infusion. The infusion takes 20 minutes and then after that you wait half an hour to see if you have a reaction. Only a mild headache so far. I go home and sleep a lot for the next few hours then good to go. Highly recommended by me.

Thanks Man, Just had an appointment with my neurologist yesterday and we decided to stick with Vyvgart for 1 more cycle then pick up with IMAAVY after the next break (as long as the insurance will track). Your recommendation means a lot🤙

I just started Imaavy two weeks ago. Having second dose as I write this. Have Triple Seronegative MG and this is my first IV treatment. My muscles started feeling more responsive the same day. Vision improved some what on day two. I seem to be feeling a little stronger almost every day. I'm very impressed so far and have high hopes. IV's don't take very long either.

Are you wondering if Imaavy might be an option after Vyvgart has plateaued for you?

Imaavy (nipocalimab-aahu) is a newer FcRn blocker that was approved in April 2025 for people 12 and older with generalized MG who are AChR- or MuSK-positive. It works similarly to Vyvgart by lowering harmful antibody levels in the body.

Are you wondering if Imaavy might be an option after Vyvgart has plateaued for you?

Imaavy (nipocalimab-aahu) is a newer FcRn blocker that was approved in April 2025 for people 12 and older with generalized MG who are AChR- or MuSK-positive. It works similarly to Vyvgart by lowering harmful antibody levels in the body.

Since both medications are FcRn blockers that target the same pathway, your doctor can help determine if switching might benefit you. They'll consider factors like:

- Your antibody status (AChR or MuSK positive)
- How your symptoms have changed on Vyvgart
- Whether a different FcRn blocker might work better for you
- Other treatment options that might be combined with or replace your current therapy

It's worth having a conversation with your healthcare provider about whether Imaavy or other treatment adjustments could help you get better symptom control. Treatment plans often need to be adjusted over time as MG changes or when one approach stops working as well.
