Can valproic acid be used with other drugs for absence seizures?
Valproic acid is a common medication for absence seizures. The FDA has approved it for use both alone (monotherapy) and together with other seizure medications (adjunctive therapy). This means doctors can prescribe valproic acid alongside other drugs to help control absence seizures, especially when a patient has more than one type of seizure.
What the research says
Multiple FDA approvals confirm that valproic acid is indicated for adjunctive therapy of simple and complex absence seizures, as well as for patients with multiple seizure types that include absence seizures 123456. This means it can be used with other antiepileptic drugs. A 2013 review by the International League Against Epilepsy (ILAE) evaluated evidence for initial monotherapy but did not directly address combination therapy 7. For juvenile myoclonic epilepsy, which often includes absence seizures, valproic acid is a first-line treatment, and other drugs like lamotrigine may be considered if valproic acid is not suitable 8. A 2017 review noted that ethosuximide or valproic acid are most often used for absence epilepsy, but when these fail or are not tolerated, other options are needed 9. The FDA sources consistently state that valproic acid can be used as adjunctive therapy, supporting its use with other drugs.
What to ask your doctor
- What are the benefits and risks of adding another seizure medication to valproic acid for my absence seizures?
- Are there specific drug interactions I should be aware of between valproic acid and other medications I take?
- How will we monitor my response if we start combination therapy?
- If valproic acid alone is not controlling my seizures, what other medications could be added?
