Drugs Class ::

 Action Believed to work by increasing brain levels of GABA. It may also inhibit catabolism of GABA, potentiate postsynaptic GABA responses, and affect potassium channels or directly stabilize membranes.

Indications for Drugs ::

 Indications Sole and adjunctive therapy in simple (petit mal) and complex absence seizures. Adjunctive therapy in multiple seizure types including absence seizures. Divalproex sodium is used for manic episodes associated with bipolar disorder.

Treatment of atypical absence, myoclonic and tonic-clonic (grand mal) seizures, and atonic, complex partial, elementary partial, and infantile spasm seizures; prevention of recurrent pediatric febrile seizures; intractable status epilepticus in patients who have not responded to other therapies; treatment of minor incontinence after ileoanal anastomosis (subchronic administration); migraine prophylaxis; management of anxiety disorders and panic attacks.

Drug Dose ::



Adults and Children: PO 15 mg/kg/day in divided doses if total dose is more than 250 mg/day; increase at 1-wk intervals by 5 to 10 mg/kg/day until seizures are controlled; side effects preclude further increases or a maximum dose of 60 mg/kg/day. Titrate and individualize based on outcomes or side effects.

Mania (Divalproex Sodium)

Adults: PO 750 mg/day in divided doses. Increase as rapidly as possible to achieve the lowest therapeutic dose that produces the desired clinical effect. Maximum dosage 60 mg/kg/day.

Contraindication ::

 Contraindications Hepatic disease dysfunction; known urea cycle disorders.

Drug Precautions ::


Pregnancy: Category D. Risk of neural tube defects may be increased during first trimester. Lactation: Excreted in breast milk. Children: In children younger than 2 yr, use drug with extreme caution. This patient group is at considerably increased risk of developing fatal hepatotoxicity. Safety and efficacy of divalproex sodium for treatment of acute mania have not been studied in patients younger than 18 yr. Safety and efficacy of long-term use (more than 3 wk) have not been systematically evaluated. If used for extended periods, continually reevaluate the drug’s usefulness. Younger children, especially if receiving enzyme-inducing drugs, will require larger maintenance doses to reach targeted drug concentrations. Elderly: Reduce starting dose and base therapeutic dose on clinical response. Acute head injuries: Because IV valproic acid has been associated with a higher incidence of death than IV phenytoin, do not use in the prevention of posttraumatic seizures in patients with acute head injuries. Bioavailability: Bioavailability problems may occur when converting to generic forms. Concurrent anticonvulsant use: Valproic acid may interact with other anticonvulsant medications. Discontinuation: Abrupt discontinuation may precipitate status epilepticus with attendant life-threatening hypoxia in patients receiving valproic acid to prevent major seizures. GI irritation: Sustained-release divalproex sodium may be less irritating to GI system than valproic acid. Hematologic effects: Drug may cause bleeding disorders. Hepatotoxicity: Hepatic failure resulting in fatalities has occurred. Children younger than 2 yr are at increased risk of developing fatal hepatotoxicity. Reactions usually occur within first 6 mo of therapy preceded by symptoms such as lost seizure control, malaise, weakness, lethargy, facial edema, anorexia, jaundice, and vomiting. Use drug with caution in patients with prior history of liver disease. Monitor results of LFTs frequently. Pancreatitis: Life-threatening pancreatitis has been reported in adults and children. Hyperammonemia: May occur with or without lethargy and coma and contribute to hepatotoxicity. Dose-related adverse reactions: Frequency of adverse reactions (particularly elevated liver enzymes, thrombocytopenia) may be dose related. Mania: Clinical data from long-term studies (more than 3 wk) are not available.
