The intravenous form is used for status epilepticus that does not improve with benzodiazepines. It may also be used for certain heart arrhythmias. Dilantin comes as a chewable tablet, an extended-release tablet, and a liquid to take by mouth. The recommended adult dose is typically 100 milligrams (mg), two to four times a day.
