Phenytoin must be infused slowly to avoid dangerous changes in blood pressure and heart rhythm. The safe maximum infusion rate for IV phenytoin is about 50 mg per minute. For a 100 mg dose, giving it at that rate requires at least 2 minutes. In practice, ensure administration through a normal saline line (not dextrose), preferably a dedicated IV site, and monitor the patient during the infusion.
