Valproic acid is indicated for which of the following seizure types?

• A. Focal seizures
• B. Tonic seizures
• C. Generalized seizures
• D. Myoclonic seizures

Answer: (C)

Valproic acid is a broad‑spectrum anticonvulsant, meaning it works well across many seizure types. It helps dampen brain-wide excitability by increasing GABA levels and by blocking sodium channels and certain calcium channels, which reduces abnormal firing in widespread networks. Because generalized epilepsies involve such networks, valproic acid is especially effective for generalized seizures, including generalized tonic-clonic, absence, and myoclonic types. While it can be used for some focal seizures in certain patients, its strongest and most consistent indication is for generalized seizures, which is why this option is the best choice.
