Methsuximidedosage

methsuximide 300 MG Oral Capsule [Celontin]

Dosage and administration

Optimum dosage of Celontin must be determined by trial. A suggested dosage schedule is 300 mg per day for the first week. If required, dosage may be increased thereafter at weekly intervals by 300 mg per day for the three weeks following to a daily dosage of 1.2 g. Because therapeutic effect and tolerance vary among patients, therapy with Celontin must be individualized according to the response of each patient. Optimal dosage is that amount of Celontin which is barely sufficient to control seizures so that side effects may be kept to a minimum. Celontin may be administered in combination with other anticonvulsants when other forms of epilepsy coexist with absence (petit mal).
