Hi CommunityMember06345b, and welcome! I see you are a new member here, having joined today, just about 2 hours ago. We are glad to see you already engaging with the community through this, your first post.
I am hopeful others in the community, who have experience with Nucala, will chime in and share their stories with you. In the meanwhile, I thought you might want to look over the published material we have (right here on asthma.net), which speaks to the use of Nucala. For your convenience, here is a link to those articles: https://asthma.net/search?s=nucala.
I do hope the information is helpful for you in a practical way.
Have you and your wife had an opportunity to discuss this type of treatment with your physician?
Wishing you well,
Leon (site moderator asthma.net)
