Dosages

Polyarticular juvenile idiopathic arthritis (JIA); juvenile psoriatic arthritis (PsA)
  • Oral
    • ≥ 2 years and 10 up to 20 kg
      • 6.4 mg/day in 2 doses.
    • ≥ 2 years and 20 up to 40 kg
      • 8 mg/day in 2 doses.
    • ≥ 2 years and ≥ 40 kg
      • 10 mg/day in 2 doses.

Renal impaiment in children > 3 months

GFR ≥30 ml/min/1.73 m2: Dose adjustment is not necessary.

GFR <30 ml/min/1.73 m2:
Children ≥40 kg: 5 mg 1dd
Children <40 kg: no data available

Clinical consequences

In renal impairment, the AUC of tofacitinib increases. This increases the risk of haematological toxicity.

Patients on dialysis

Children ≥40 kg: 5 mg 1dd
Children <40 kg: no data available

Warnings & precautions in children

If a patient develops a severe infection, tofacitinib treatment should be interrupted until the infection is controlled.

Dose interruption may be required for the treatment of dose-related laboratory abnormalities, including lymphopenia, neutropenia and anaemia. Based on the severity of the laboratory abnormalities, it is recommended to temporarily interrupt or permanently discontinue treatment (see SmPC ).

Initiation of treatment is not recommended in patients with an absolute lymphocyte count (ALC) below 750 cells/mm3, an absolute neutrophil count (ANC) below 1,200 cells/mm3 or a hemoglobin value below 6.1 mmol/L (10 g/dl).
