Dosing and rate of administration in Dermatomyositis

Dosing and rate of administration for adults with Dermatomyositis (DM) 4

  • The dose may need to be individualised for each patient dependent on the clinical response. Dose based on body-weight may require adjustment in underweight and overweight patients. In over-weight patients dose should be based on the physiological standard bodyweight4

  • The initial infusion rate should be maintained for 30 minutes, and if tolerated, the infusion rate may be gradually increased every 30 minutes to a maximum of 4 mg/kg/min (0.04 mL/kg/min) as tolerated 4 †

  • Patients with DM are at increased risk for thromboembolic events; monitor carefully and do not exceed an infusion rate of 0.04 mL/kg/min4

  • Ensure that patients with pre-existing renal insufficiency are not volume depleted. For patients at risk of renal dysfunction or thromboembolic events, administer octagam®10% at the minimum infusion rate practicable, not to exceed 3.3 mg/kg/min (0.03 mL/kg/min). Discontinue octagam®10% if renal function deteriorates4

Monitor the patient carefully throughout the infusion. Certain adverse reactions may be related to the rate of infusion. Slowing or stopping the infusion usually allows the symptoms to disappear promptly. Once the symptoms subside, the infusion may then be resumed at a lower rate.4
