Hi @jjtaylor95 -- Welcome to Connect. I don't have GPA or meningitis. I'm hoping a member with similar health experiences will share their experiences with you. I did a search and found a few links that may provide some helpful information until someone else responds to your question.

@jjtaylor95 have you asked your doctor about the immunosuppressants that you are on? Just wondering if there may be a better substitute.
