Understanding Epilepsy -- Symptoms

 Seizures are the basic indicator of epilepsy. They vary widely: Staring straight ahead, repetitive swallowing, and lapsing into complete immobility for a few seconds characterize absence (petit mal) seizures, which can recur many times in a day.

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.   

Tegretol or Carbatrol (carbamazepine)

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

Zarontin (ethosuximide)

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

Felbatol (felbamate)

  • Treats partial and some generalized seizures; 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.

Gabitril (tiagabine)

  • Used with other epilepsy drugs to treat partial and some generalized seizures
  • Common side effects include dizziness, fatigue, weakness, irritability, anxiety, and confusion.

  • Has few side effects, but rarely people report dizziness, insomnia, or rash.

Dilantin (Phenytoin)

  • Controls partial seizures and generalized tonic-clonic seizures; also can be given by vein (intravenously) in the hospital to rapidly control active seizures, although if the drug is being delivered by IV, Cerebyx (fosphenytoin) is usually used.
