I've been taking Xolair for the last ~4 years for general allergies (with stellar results) and at least for my regimen, it's only once a month, not twice.
My partner was on Dupixent for a while to shrink some nasal polyps—that one is twice a month.
Interesting. I looked at a dosage chart and it seems like you do either once or twice a month based on your IgE level determined by a blood test. So it is twice a month for some people.
