Dosage of Stiripentol

1.Laboratory Tests Prior to First Dose of Stiripentol

Hematologic testing should be obtained prior to starting treatment with Stiripentol.

2.Dosing Information

The recommended oral dosage of Stiripentol is 50 mg/kg/day, administered in 2 or 3 divided doses (i.e.,16.67 mg/kg three times daily or 25mg/kg twice daily), depending on the patient’s age and body weight as shown in Table 1. If the exact dosage is not achievable given the available strengths, round to the nearest possible dosage, which is usually within 50 mg to 150 mg of the recommended 50 mg/kg/day. A combination of the two Stiripentol strengths can be used to achieve this dosage. The maximum recommended total dosage is 3,000 mg/day.

3.Important Administration Instructions

Stiripentol Capsules

Stiripentol capsules must be swallowed whole with a glass of water during a meal. Capsules should not be broken or opened. 

Stiripentol for Oral Suspension

Stiripentol should be mixed in a glass of water (100 mL) and should be taken immediately after mixing during a meal. To be sure there is no medicine left in the glass, add a small amount of water (25 mL) to the drinking cup and drink all of the mixture.

4.Missed Dose

A missed dose should be taken as soon as possible. If it is almost time for the next dose, the missed dose should not be taken. Instead, the next scheduled dose should be taken. Doses should not be doubled.

5.Gradual Withdrawal

As is advisable for most antiepileptic drugs, if Stiripentol treatment is discontinued, the drug should be withdrawn gradually to minimize the risk of increased seizure frequency and status epilepticus.

In situations where rapid withdrawal of Stiripentol is medically required, appropriate monitoring is recommended.
