What are the most common seizure medications?

First-line therapy for generalized tonic-clonic (grand mal) seizures includes valproic acid (Depakene, Depakote), lamotrigine (Lamictal) and topiramate (Topamax).

For partial seizures, common first-line medications include carbamazepine (Tegretol), phenytoin (Dilantin), Oxcarbazepine (Trileptal) and, especially in children, ethosuximide (Zarontin).

Additionally, phenobarbital is often the medication of choice for seizures in very young children.

What are common seizure medication side effects?

Because seizure medications work in the central nervous system, most cause some degree of drowsiness or dizziness, at least at the beginning of therapy. Also, most anti-seizure medications can induce suicidal thoughts or actions, and/or bring on or worsen depression.

Seizure medications have a variety of possible side effects. The following is a list of potential side effects of different classes of seizure medications.
