VALPROATE SODIUM
Valproate sodium injection is an intravenous alternative for patients who are temporarily unable to receive oral valproate medications. It is indicated for the treatment of complex partial seizures, simple and complex absence seizures, and multiple seizure types that include absence seizures. The medication is utilized as both monotherapy and adjunctive therapy depending on the specific seizure type and clinical presentation. Use is restricted in pregnant women and women of childbearing potential due to risks of major congenital malformations and neurodevelopmental disorders.
How VALPROATE SODIUM Works
Valproate sodium exists as the valproate ion within the bloodstream. Although the exact mechanisms of its therapeutic effects have not been fully established, its activity in treating epilepsy is suggested to be related to neurotransmitter levels. Specifically, the drug is thought to work by increasing the concentrations of gamma-aminobutyric acid (GABA) in the brain.

WARNING: LIFE THREATENING ADVERSE REACTIONS WARNING: LIFE THREATENING ADVERSE REACTIONS See full prescribing information for complete boxed warning. • Hepatotoxicity, including fatalities, usually during the first 6 months of treatment. Children under the age of two years and patients with mitochondrial disorders are at higher risk. Monitor patients closely, and perform serum liver testing prior to therapy and at frequent intervals thereafter ( 5.1 ) • Fetal Risk, particularly neural tube defects, other major malformations, and decreased IQ ( 5.2 , 5.3 , 5.4 ) • Pancreatitis, including fatal hemorrhagic cases ( 5.5 ) Hepatotoxicity General Population: Hepatic failure resulting in fatalities has occurred in patients receiving valproate and its derivatives. These incidents usually have occurred during the first six months of treatment. Serious or fatal hepatotoxicity may be preceded by non-specific symptoms such as malaise, weakness, lethargy, facial edema, anorexia, and vomiting. In patients with epilepsy, a loss of seizure control may also occur. Patients should be monitored closely for appearance of these symptoms. Serum liver tests should be performed prior to therapy and at frequent intervals thereafter, especially during the first six months [see Warnings and Precautions ( 5.1 )] . Children under the age of two years are at a considerably increased risk of developing fatal hepatotoxicity, especially those on multiple anticonvulsants, those with congenital metabolic disorders, those with severe seizure disorders accompanied by mental retardation, and those with organic brain disease. When valproate sodium injection is used in this patient group, it should be used with extreme caution and as a sole agent. The benefits of therapy should be weighed against the risks. The incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups.
