What is the recommended Saphnelo (anifrolumab) dosing schedule?
Saphnelo (anifrolumab) is given by intravenous (IV) infusion. The dosing used for the approved indication is 300 mg every 4 weeks. [1]
How is Saphnelo administered (what happens during an infusion)?
Saphnelo is administered as an IV infusion at a clinical setting. Your prescriber will set the infusion timing based on your treatment plan and local infusion procedures, but the standard dose is 300 mg. [1]
What should I do if I miss a dose or my infusion appointment is delayed?
The usual approach is to reschedule as soon as possible and continue the 4-week dosing interval from the rescheduled date. Your treatment team should confirm the exact plan based on how far the delay is. [1]
Who should avoid Saphnelo or get extra monitoring?
If you have serious active infections or a history of recurrent infections, your clinician may decide whether Saphnelo is appropriate and how closely to monitor you during treatment. [1]
What drug interactions or vaccines timing should I consider?
Your clinician should review vaccines and other therapies you take while on Saphnelo, since immunomodulating biologics can affect infection risk and vaccine planning. Follow the guidance provided by your treating team. [1]
Where can I find official dosing instructions?
Use the prescribing information (label) for your country, since dosing language and administration details are specified there. The standard regimen is 300 mg IV every 4 weeks. [1]
