Detailed Phenytoin dosage information for adults and children. phenytoin loading dose emedicine Treatment can be initiated either with a loading dose or an infusion: LOADING DOSE.
This calculator uses the average of the following correction equations. Note that these equations are a variant of the traditional Winter-Tozer equation, which has been demonstrated to be less accurate more information.
Based on this study alone, the following equation is the suggested obesity adjustment for loading doses: Because its molecular weight is different than that of phenytoin, one milligram of fosphenytoin does not equal one milligram of phenytoin. To avoid confusion, fosphenytoin doses are reported as "mgPE" milligrams of phenytoin equivalents.
Using mgPE, no adjustment is needed when converting between phenytoin and fosphenytoin. IV Loading Doses Phenytoin oral loading doses may be advantageous in stable patients with subtherapeutic phenytoin concentrations, particularly in those presenting to the emergency department without IV access.

Only should be used in an inpatient setting, or if in an outpatient setting, with close follow-up and monitoring of levels.
Should not be used in patients with liver or kidney dysfunction. Onset of initial response is usually hours. Peak concentration is usually reached in hours. If using IV phenytoin, the patient should be on telemetry due to the risk of cardiac effects including dysrhythmias, hypotension, bradycardia and cardiac arrest. Onset of initial response is usually immediate. Peak concentration with a loading dose is usually reached in minutes.
Maintainence A typical maintainence dose is mg PO, which can be divided into twice daily dosing. Onset of initial response is generally days.
