Treatment of febrile seizures: historical perspective, current opinions, and potential future directions.
Although most febrile seizures do no harm and two-thirds of initial cases have no witnessed recurrence, the seizures cause much family anxiety, and are sometimes prolonged. In rare cases they are the first evidence of important epilepsy syndromes or are implicated in the development of epilepsy with mesial temporal sclerosis in later life. There have been trials of prophylactic treatment with antiepileptic drugs including carbamazepine, diazepam, phenobarbital, phenytoin, and sodium valproate. Several strategies have been employed with these drugs, including continuous secondary prophylaxis, intermittent secondary prophylaxis in response to later episodes of fever, and rescue medication early in the course of further seizures. Another treatment strategy has been using one or more antipyretic agents in early response to fever using agents such as acetaminophen and ibuprofen. Over the years, researchers have identified a variety of clinical, genetic, and environmental risk factors for more severe or prolonged febrile seizures and higher risk of recurrence. This review evaluates the rationale for secondary prophylaxis of febrile seizures, the potential effectiveness of such treatment, and whether it can be recommended as a general approach to treating febrile seizures or as an approach to be used in groups identified to be at increased risk.
