Valproate

Valproate is an anticonvulsant and mood-stabilizing drug. It works by increasing levels of GABA (gamma-aminobutyric acid) in the brain, which helps prevent seizures and stabilize mood. Due to its potential for serious side effects, including liver damage, pancreatitis, and severe birth defects (teratogenicity), its use must be closely monitored by a healthcare professional.

Dosage by Body Weight

Dosage must be individualized. Typically started at 10-15 mg/kg/day and titrated slowly up to 20-30 mg/kg/day based on response. Take with or after food to minimize stomach upset. Do not crush or chew prolonged-release or enteric-coated tablets. High risk of birth defects; female patients must follow strict pregnancy prevention programs.
