Stiripentol (Diacomit) is an anticonvulsant drug that belongs to a different class of medicines called aromatic allylic alcohols. It is used to treat seizures in patients with Dravet syndrome.
Stiripentol Uses:
-
Dravet syndrome:
- Patients with Dravet syndrome, formerly known as severe myoclonic epilepsy in infancy, may receive clobazam and valproic acid as an adjunctive treatment for refractory generalised tonic-clonic seizures (Chiron 2000; Wirrell 2016).
Stiripentol (Diacomit) Dose in Adults
Note:
- Not appropriate for monotherapy.
- The dosage of concomitant clobazam and valproate may need adjustment.
- Systemic exposure is slightly higher with the suspension powder than that observed with capsules;
- patient monitoring is strictly recommended when changes between dosage forms are required (Canadian labeling).
Stiripentol (Diacomit) Dose in the treatment of Dravet syndrome as adjunctive therapy) :
- Oral: Usual: According to some experts, you should start with 10 to 15 mg/kg/day and work your way up to a goal dose of 50 mg/kg/day over the course of 2 to 4 weeks.
- Maximum dose: 3 g/day (manufacturer’s labeling).
- Given in two or three divided dosages each day, 50 mg/kg/day.
Stiripentol (Diacomit) Dose in Children
Note:
- FDA approved in combination with clobazam;
- international labeling (European Medicines Agency, Health Canada) suggested combination with clobazam and valproic acid.
- Other concomitant antiepileptic agents have been studied as well (eg, topiramate) and efficacy data are changing continuously; although, experts recommend avoiding sodium channel blockers (eg, carbamazepine) which may exacerbate seizures.
- The concomitant dosage of clobazam and/or valproate may need adjustment with initiation of stiripentol.
- Systemic exposure is slightly higher with the powder for suspension than that observed with capsules; patient monitoring is recommended when switching between dosage forms.
- Two strengths of powder packets are available (250 mg and 500 mg);
- may combine the two strengths to achieve the appropriate dosage; ensure appropriate product selection.
Stiripentol (Diacomit) Dose in the treatment of Dravet syndrome as adjunctive therapy:
-
Children and Adolescents: Limited data available in children <2 years of age:
- Oral: The maximum daily dose is 3,000 mg/day, which is given in two or three divided doses of 50 mg/kg/day.
- Some professionals advise starting with a lower dose of 10 to 15 mg/kg/day in divided doses and gradually increasing to the initial target dose of 50 mg/kg/day over the course of two to four weeks.
Pregnancy Risk Category: Not assigned
- Animal reproduction studies have shown that adverse events were reported. We have not found any information regarding the use of stiripentol in pregnancy.
- Stiripentol can be used with clobazam and valproic acids (off-label); see individual monographs to get more information.
- Monitoring of pregnancy and infant adverse reactions to stiripentol exposure is ongoing.
Use of stiripentol while breastfeeding
- It is unknown if stiripentol can be found in breast milk.
- Stiripentol can be used with clobazam and valproic acids (off-label); see individual monographs to get more information.
- According to the drug's manufacturer, the choice of whether to stop or continue breastfeeding during therapy must be made while taking into account both the advantages of the therapy for both the mother and the baby.
Stiripentol (Diacomit) Dose in Kidney Disease:
- The drug manufacturer's labeling does not include any dosage adjustments (has not yet been studied).
- Take care with mild impairment. Use caution.
- Patients with severe or moderate renal impairment should not use this product.
Stiripentol (Diacomit) Dose in Liver disease:
- The drug manufacturer's labeling does not contain any dosage adjustments (has not been tested).
- When mildly impaired, exercise caution; gradually increase the dose to control seizures and tolerability. The liver is the primary site of metabolism.
- This product should not be used by patients with severe or moderate hepatic impairment.
Note:
- Adverse reactions reported with combination (clobazam) therapy.

Warnings and precautions
-
Weight loss/appetite
- Clinical trials have shown that weight loss and appetite reduction were observed in 46% of patients and 27% of those who had participated (mean age 9.2 years).
- Monitor the growth rate for pediatric patients.
- A 30% reduction in the dose of valproate may be helpful for weight loss and appetite control.
-
Blood dyscrasias
- In clinical trials, thrombocytopenia and neutropenia were observed. Monitor CBC during therapy.
-
Depression in the CNS:
- CNS depression can occur (eg, sleepiness, drowsiness), and may cause impairment of physical or mental abilities.
- Patients should be warned about driving or operating machinery that requires mental alertness.
- Consider adjusting the dosage of Clobazam or other antiseizure medications if you experience CNS depression while taking clobazam.
-
Suicidal thoughts:
- No matter the antiepileptic drug's intended use, a pooled analysis of these trials revealed an increase in suicidal thoughts and actions (incidence rate of 0.43% treated patients versus 0.24% placebo); this risk became apparent as early as one week after the drug was started and persisted for the majority of the trial's duration (most trials were less than 24 weeks).
- Watch out for any changes in behavior or thoughts that could indicate depression or suicidal thoughts. Notify your health care provider immediately if you notice these symptoms.
-
Hepatic impairment
- Patients with mild impairment should be cautious; the liver metabolism is the primary focus.
- Patients with severe or moderate hepatic impairment should not use this product.
-
Renal impairment
- Patients with mild impairment should be cautious; elimination of metabolites occurs primarily through the kidneys.
- Patients with severe or moderate renal impairment should not use this product.
