More than one in every one hundred patients presenting to the emergency department for care do so for seizures. More than half of these patients will require medications, often intravenously (IV), while in the emergency department. For many years the standard treatment has been phenytoin. However, there are many known contraindications to the use of this drug. These include known hypersensitivity, cardiac arrhythmias, cardiac disease, impaired liver or kidney function, diabetes mellitus, older age, thyroid disease, pregnancy, and alcohol use. A recent review of patients with seizure disorder at Emory Crawford Long and Emory University hospitals suggested that a significant percentage of those who were taking phenytoin actually had one or more of these contraindications. Additionally, the IV form of phenytoin has known, severe adverse effects including cardiovascular collapse, life threatening cardiac arrhythmias, and severe hypotension. There is another form of Phenytoin, called Fosphenytoin, that while safer in some respects still has similar concerns associated with its administration.
