Comments:
  • A dose of 20 mg/kg/day has demonstrated a greater reduction in seizure rates, but is associated with an increase in adverse reactions.

Maintenance dose: 10 to 20 mg/kg/day in 2 divided doses
Maximum dose: 20 mg/kg/day

Comments:
  • A dose of 20 mg/kg/day has demonstrated a greater reduction in seizure rates, but is associated with an increase in adverse reactions.
  • Consistent dosing with respect to meals is recommended to reduce variability in cannabidiol plasma exposure.

Use: For the treatment of seizures associated with Lennox-Gastaut syndrome or Dravet syndrome in patients 1 year and older.

Usual Pediatric Dose for Dravet Syndrome

1 year or older:

Renal Dose Adjustments

No adjustment recommended

Liver Dose Adjustments

Mild hepatic impairment: No adjustment recommended

Moderate hepatic impairment (Child-Pugh B):

  • Initial dose: 1.25 mg/kg orally twice a day
  • Maintenance dose (Lennox-Gastaut syndrome; Dravet syndrome): 2.5 to 5 mg/kg orally twice a day
  • Maintenance dose (tuberous sclerosis complex): 6.25 mg/kg orally twice a day

Severe hepatic impairment (Child-Pugh C):

  • Maintenance dose (tuberous sclerosis complex): 2.5 mg/kg orally twice a day

Comments:
  • For patients with moderate to severe hepatic impairment, it may be necessary to have a slower dose titration.
  • Discontinue therapy for transaminase elevations greater than 3 times upper limit of normal (3 x ULN) and bilirubin levels greater than 2 x ULN
  • Discontinue therapy for sustained transaminase elevations greater than 5 x ULN

Dose Adjustments

Elderly: Dose selection should be cautious, usually starting at the low end of the dosing range

Discontinuation of therapy:

  • Gradual dose reduction is recommended to reduce the risk of increased seizure frequency and status epilepticus.

Precautions

Other Comments

Administration advice:

  • For oral administration only
  • Take consistently with or without food to reduce variability in plasma exposure
  • A calibrated measuring device should be used to ensure accuracy in dosing
  • Enteral feeding tube (nasogastric or gastrostomy) may be used if needed: do not use tubes made of polyvinyl chloride (PVC)

Storage requirements:
  • Store upright at 20C to 25C (68F to 77F); excursions permitted 15C to 30C (59F to 86F)
  • Do not refrigerate or freeze
  • Keep cap tightly closed
  • Use within 12 weeks of opening bottle; discard any remainder

Reconstitution/preparation techniques:
  • Product will be dispensed with a bottle adapter and 5 mL oral syringe
  • If dose is less than 100 mg (1 mL), the pharmacist should provide a 1 mL oral syringe

Monitoring:
  • Obtain baseline serum transaminases (ALT and AST) and total bilirubin levels; repeat at 1, 3, and 6 months, then periodically or as clinically indicated.
  • Additionally, serum transaminase and total bilirubin levels should also be obtained within 1 month a change in dose of this drug or changes in medications that are known to impact the liver
  • Increased monitoring should be considered in those concomitantly taking valproate or who have elevated liver enzymes at baseline.
  • Monitor for emergence or worsening of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts of self-harm

Patient Advice:
  • Read the US FDA-approved patient labeling (Medication Guide and Instructions for Use).
  • Patients should understand that this drug may be taken with or without food, however, once decided, it should always be taken the same way.
  • Patients should be advised of the signs and symptoms of hepatic dysfunction and the need to contact their healthcare provider if these occur.
  • Patients should be advised not to drive or operate hazardous equipment until they understand how this drug affects them.
  • Patients should be instructed not to abruptly discontinue therapy without talking with their health care provider.
  • Patients, families, and caregivers should understand that this drug may increase the risk of suicidal thoughts and behavior and they should be instructed to report any unusual change in mood or behavior, worsening of depression, or suicidal thoughts or behaviors to their healthcare provider immediately.
