Seizure Medications

January 29, 2021

When seizures have known causes such as diabetes, high fever, abnormal blood levels of sodium, or infection, the cure is to correct the underlying condition. When seizures occur more than once for causes that cannot be diagnosed, patients are said to have seizure disorders, or epilepsy, and seizure disorders are usually treated with seizure medications. For reasons not fully understood, electrical impulses in the brain become abnormal, causing signs and symptoms such as loss of consciousness, abnormal movements, deja-vu experiences, fear, and apparent flashing lights.

When seizure disorder is diagnosed, physicians usually prescribe antiseizure medications. Staying on a strict medication schedule is important to avoid further seizures. Even missing just one dose can trigger a seizure. Patients usually remain on these medications for 2 to 4 years, then sometimes tapering off may be considered by the neurologist if the patient remained seizure-free during that time.
