      • Premedication:

        • Methylprednisolone IV 30 mg / kg / day in 1 dose or 60 mg / / kg / day in 2 doses, max 1 g / day on 3 consecutive days prior to the first infusion of rituximab. The last dose methylprednisolone may be administerred shortly before the rituximab infusion. 
        • Prednisolone orally 1 mg / kg / day, max 60 mg/dag. Start at day of rituximab infusion. Taper prednisolone as soon as possible if clinically necessary

Warnings & precautions in children

Recommended infusion duration: 3 hours. Fever, chills or rigor may occur during the first infusion. Premedication consisting of paracetamol and an antihistamine must therefore be given before each dose. Be aware of the possibility of blood pressure drops and bronchial spasms. The infusion rate of the first infusion should therefore be increased slowly.

Prophylaxis for Pneumocystis jiroveci pneumonia (PJP) is recommended in children with GPA or MPA during and after treatment with rituximab, as appropriate.
