Dosing And Administration of RYANODEX® During An MH Crisis7

Administer RYANODEX® by intravenous push at a minimum dose of 1 mg/kg. If the physiologic and metabolic abnormalities of MH continue, administer additional intravenous boluses up to the maximum cumulative dosage of 10 mg/kg. If the physiologic and metabolic abnormalities reappear, repeat RYANODEX® dosing by intravenous push starting with 1 mg/kg.

In addition to RYANODEX® treatment, institute the following supportive measures:

  • Discontinue use of MH-triggering anesthetic agents (volatile anesthetic gases and succinylcholine)
  • Manage the metabolic acidosis
  • Institute cooling as necessary
  • Maintain adequate diuresis as needed
