ADULTS
For people 8 years of age and older who have not been treated before the recommended dosing of Mysoline is as follows using either 50-milligram or scored 250-milligram Mysoline tablets:
Days 1 to 3: 100 to 125 milligrams at bedtime
Days 4 to 6: 100 to 125 milligrams 2 times a day
Days 7 to 9: 100 to 125 milligrams 3 times a day
Day 10 to maintenance: 250 milligrams 3 times a day
For most adults and children 8 years of age and over the usual maintenance dosage is 250 milligrams 3 or 4 times a day. If you need more your doctor may increase the dose to five or six 250-milligram tablets. You should not take more than 500 milligrams 4 times a day (2000 milligrams or 2 grams).
In patients already receiving other anticonvulsants the usual starting dose of Mysoline is 100 to 125 milligrams at bedtime; your doctor may gradually increase this dose to a maintenance level as the other drug is gradually decreased. Your doctor may either find a working level for the combination or withdraw the other medication completely. When Mysoline is to be used as a single drug it may take at least 2 weeks to make the transition from two drugs to one.

Days 4 to 6: 50 milligrams 2 times a day
Days 7 to 9: 100 milligrams 2 times a day

The usual maintenance dosage is 125 to 250 milligrams 3 times daily or 10 to 25 milligrams per 2.2 pounds of body weight per day divided into smaller doses.
