Read the guide → Studysummary This review highlights valproic acid's efficacy and tolerability as a first-line treatment for various seizure types in both adults and children, emphasizing its minimal neurological adverse effects compared to other antiepileptic drugs. Our plain-language summary of this paper — not a Tressless recommendation.
Valproic acid, a branched-chained fatty acid, was found to be effective and safe for treating various types of seizures in both adults and children, including generalized seizures (absence, tonic-clonic, myoclonic), partial seizures, and compound/combination seizures. It showed efficacy comparable to other antiepileptic drugs like carbamazepine and phenytoin. Common side effects included gastrointestinal issues, weight gain, tremor, and transient hair loss, with minimal neurological adverse effects. The risk of rare, fatal liver failure was reduced by avoiding use in high-risk patients. There was a reported 1-2% risk of neural tube defects with maternal use. Valproic acid's interaction with other drugs required careful dosage adjustments. Overall, it was considered a valuable first-line treatment for a broad range of seizure types.
