Increase at weekly intervals by adding up to 200 mg/day using a b.i.d or a t.i.d. or q.i.d. regimen of the either formulations until the optimal response is obtained. Dosage generally should not exceed 1000 mg daily in children 12-15 years of age, and 1200 mg daily in patients above 15 years of age. Doses up to 1600 mg daily have been used in adults in rare instances. Maintenance: usually 800-1200 mg daily. Children 6-12 years of age – Initial: Either 100 mg b.i.d. for tablets or XR tablets, or 1/2 teaspoon q.i.d. for suspension (200 mg/day). Increase at weekly intervals by adding up to 100 mg/day using a b.i.d. or a t.i.d. or q.i.d. regimen of the either formulations until the optimal response is obtained. Dosage generally should not exceed 1000 mg daily. Maintenance: usually 400-800 mg daily. Children under 6 years of age – Initial: 10-20 mg/kg/day b.i.d. or t.i.d. as tablets, or q.i.d. as suspension. Increase weekly to achieve optimal clinical response administered t.i.d. or q.i.d. Maintenance: Ordinarily, optimal clinical response is achieved at daily doses below 35 mg/kg. If satisfactory clinical response has not been achieved, plasma levels should be measured to determine whether or not they are in the therapeutic range. No recommendation regarding the safety of Carbamazepine for use at doses above 35 mg/kg/24 hours can be made. Combination therapy: Carbamazepine may be used alone or with other anticonvulsants. When added to existing anticonvulsant therapy, the drug should be added gradually while the other anticonvulsants are maintained or gradually decreased, except phenytoin, which may have to be increased. Trigeminal Neuralgia: Initial: On the first day, either 100 mg b.i.d. for tablets or XR tablets, or 1/2 teaspoon q.i.d. for suspension, for a total daily dose of 200 mg. This daily dose may be increased by up to 200 mg/day using increments of 100 mg every 12 hours for tablets or XR tablets, or 50 mg (1/2 teaspoon) q.i.d. for suspension, only as needed to achieve freedom from pain. A total dose of 1200 mg daily shouldn’t be exceeded. Maintenance: Control of pain can be maintained in most patients with 400-800 mg daily. However, some patients may be maintained on as little as 200 mg daily, while others may require as much as 1200 mg daily. At least once every 3 months throughout the treatment period, attempts should be made to reduce the dose to the minimum effective level or even to discontinue the drug. The tablets or syrup can be taken without regards to meal.

Drug Mode of Action ::  

Carbamazepine reduces polysynaptic responses and blocks post-tetanic potentiation. It is effective in partial and generalised convulsions as well as in mixed types but not in petit mal seizures. It reduces or abolishes pain in trigeminal and glossopharyngeal neuralgia.

Drug Interactions ::

Increased plasma levels w/ CYP3A4 inhibitors (e.g. cimetidine). Decreased plasma levels w/ CYP3A4 inducers (e.g. cisplatin). Increased risk of neurotoxic side effects w/ lithium. May decrease the effect of hormonal contraceptives. Increased plasma levels of active metabolite carbamazepine-10, 11-epoxide w/ loxapine, quetiapine, primidone, progabide, valproic acid and valpromide. May increase cyclophosphamide levels. May reduce exposure of aripiprazole. May reduce plasma levels of tacrolimus, temsirolimus and lapatinib. May increase risk of isoniazid-induced hepatotoxicity. Risk of symptomatic hyponatraemia w/ diuretics (e.g. hydrochlorothiazide, furosemide). Potentially Fatal: May decrease serum concentrations of nefazodone and its active metabolites. Toxic reactions may develop when taken concurrently w/ MAOIs.
