TLDR Valproic acid is effective for various seizures, but may cause temporary side effects like drowsiness and stomach issues.
Valproic acid was introduced as a new anticonvulsant agent effective in treating absence seizures, tonic-clonic seizures, mixed absence with tonic-clonic seizures, and myoclonic epilepsy. It could be used alone or with other anticonvulsants, potentially allowing for reduced dosages of the latter. Some patients unresponsive to other treatments showed improvement with valproic acid. Adverse reactions occurred in about 20% of patients, with gastrointestinal disturbances and drowsiness being the most common, especially when combined with other anticonvulsants. Hair loss was a less frequent side effect. These adverse effects were generally transient and did not necessitate stopping the medication.
