Below is a list of some of the most common brand-name drugs currently used to treat epilepsy. Your doctor may prefer that you take the brand name of anticonvulsant and not the generic substitution. Talk with your doctor about this important issue.

Carbamazepine (Tegretol or Carbatrol)

  • First choice for partial, generalized tonic-clonic and mixed seizures
  • Common adverse effects include fatigue, vision changes, nausea, dizziness, rash.

Diazepam (Valium ), Lorazepam (Ativan) and similar tranquilizers such as Clonazepam ( Klonopin )

  • Effective in short-term treatment of all seizures; used often in the emergency room to stop a seizure, particularly status epilepticus
  • Tolerance develops in most within a few weeks, so the same dose has less effect over time.
  • Valium can also be given as rectal suppository.
  • Side effects include tiredness, unsteady walking, nausea, depression, and loss of appetite. In children, they can cause drooling and hyperactivity.

Eslicarbazepine acetate (Aptiom)

  • This drug is used as adjunctive treatment (meaning it's taken in addition to other drugs) of partial-onset seizures.
  • The most common side effects include dizziness, nausea, headache, vomiting, fatigue, vertigo, ataxia, blurred vision, and tremor.

Ethosuximide (Zarontin)

  • Used to treat absence seizures
  • Adverse effects include nausea, vomiting, decreased appetite, and weight loss.

Felbamate (Felbatol)

  • Treats partial seizures alone and some partial and generalized seizures in Lennox-Gastaut Syndrome; is used rarely and only when no other medications have been effective.
  • Side effects include decreased appetite, weight loss, inability to sleep, headache, and depression. Although rare, the drug may cause bone marrow or liver failure. Therefore, the use of the drug is limited and patients taking it must have blood cell counts and liver tests regularly during therapy.
