What is the usual Saphnelo (anifrolumab) dosing schedule?
Saphnelo is given as an intravenous (IV) infusion. The standard dosing schedule is 300 mg once every 4 weeks (q4 weeks). [1]
How often do I receive Saphnelo infusions?
Once you start treatment, infusions are typically repeated every 4 weeks. The dose is 300 mg each time. [1]
Are there different dosing schedules for different patients?
The provided information supports a single standard regimen of 300 mg IV every 4 weeks. [1] If you have specific details from your prescribing clinician (for example, dose adjustments in special circumstances), share them and I can help interpret how they fit with the labeled regimen.
How is the dosing schedule administered (timing around visits)?
Because Saphnelo is dosed every 4 weeks, the schedule is generally tied to the infusion visit cadence (month-to-month follow-ups aligned to the same interval). [1]
What to ask your clinician if you miss or delay a dose
If you miss a planned infusion or it’s delayed, ask your clinician for the exact plan to restart and how to align future 4-week intervals. (The specific catch-up instructions depend on your situation and local protocol, and weren’t included in the provided source.)
