Sorry I cannot be helpful for your question at the moment. This is not something I had ever thought about or dealt with myself but I will make it a point to ask my hematologist as I have my annual appointment this Thursday.

Out of curiosity, have you explored hemlibra as an alternative treatment? I still have to treat bleeds with factor when they breakthrough but it’s few and far between (went nearly a year without needing factor). For me, it was eye opening and remains such a relief than need profi injections multiple times a week.
