Renvista 50 Tablet 1 Strip

✔️ Dosage & Administration

The appropriate dose of roxadustat must be taken orally three times per week and not on consecutive days. The dose should be individualized to achieve and maintain target Hb levels of 10 to 12 g/dL as described below:

Patients not on erythropoiesis-stimulating agent treatment: For adults, the usual starting dose is 50 mg three times weekly. The recommended starting dose of roxadustat is 70 mg three times per week in patients weighing less than 100 kg and 100 mg three times per week in patients weighing 100 kg and over.

Patients switching from erythropoiesis-stimulating agents: For adults, the usual starting dose is 70 or 100mg three times weekly. The dosage thereafter should be adjusted according to the patient's condition.

Dose adjustment: When dose adjustments are required, increase or decrease the dose according to the "Dose increase/decrease table" and "stepwise Dose adjustment sequence" below. Once adjusted, maintain the dose level for ≥4 weeks. If the hemoglobin concentration increases rapidly (>2.0 g/dL) within 4 weeks of a dose increase, decrease the dose or suspend the treatment immediately.

The stepwise dose adjustments up or down should follow the sequence of the available doses: 20 mg-40 mg-50 mg-70 mg-100 mg-150 mg-200 mg-250 mg-300 mg-400 mg (only for CKD patients on dialysis).

Missed dose: When there is ≥ 24-hour interval until the next scheduled dosing time, take the missed dose immediately and follow the prescribed schedule for subsequent doses. If there is <24 hours until the next scheduled dosing time, skip the missed dose, and take the next dose as scheduled. Do not take 2 doses on the same day.
