A 45-year-old member asked:

Is phenytoin more effective when taken orally or via injection?

Efficiency: Intravenous phenytoin will affect faster than oral due to the need for the latter to be absorbed in the GI tract. Once therapeutic levels are achieved, either orally or intravenously, the effect is equivalent.
