Seizures Associated with Lennox-Gastaut Syndrome or Dravet Syndrome
- PO (Adults and Children 1 yr): 2.5 mg/kg twice daily; can ↑ dose to 5 mg/kg twice daily in 1 wk. If further reduction in seizure frequency needed, may continue to ↑ dose on weekly basis (every other day if more rapid titration warranted) in increments of 2.5 mg/kg twice daily (max dose = 10 mg/kg twice daily).
Hepatic Impairment
- PO (Adults and Children 1 yr): Moderate hepatic impairment (ChildPugh B): 1.25 mg/kg twice daily; can ↑ dose to 2.5 mg/kg twice daily in 1 wk. If further reduction in seizure frequency needed, may continue to ↑ dose on weekly basis (every other day if more rapid titration warranted) in increments of 1.25 mg/kg twice daily (max dose = 5 mg/kg twice daily); Severe hepatic impairment (ChildPugh C): 0.5 mg/kg twice daily; can ↑ dose to 1 mg/kg twice daily in 1 wk. If further reduction in seizure frequency needed, may continue to ↑ dose on weekly basis (every other day if more rapid titration warranted) in increments of 0.5 mg/kg twice daily (max dose = 2 mg/kg twice daily).
Seizures Associated with Tuberous Sclerosis Complex
- PO (Adults and Children 1 yr): 2.5 mg/kg twice daily; can ↑ dose on weekly basis (every other day if more rapid titration warranted) in increments of 2.5 mg/kg twice daily to recommended maintenance dosage of 12.5 mg/kg twice daily.
Hepatic Impairment
- PO (Adults and Children 1 yr): Moderate hepatic impairment (ChildPugh B): 1.25 mg/kg twice daily; can ↑ dose on weekly basis (every other day if more rapid titration warranted) in increments of 1.25 mg/kg twice daily to recommended maintenance dosage of 6.25 mg/kg twice daily; Severe hepatic impairment (ChildPugh C): 0.5 mg/kg twice daily; can ↑ dose on weekly basis (every other day if more rapid titration warranted) in increments of 0.5 mg/kg twice daily to recommended maintenance dosage of 2.5 mg/kg twice daily.
