Not only would I choose oral for reasons of cost, convenience, and the least negative impact on my day-to-day life, I would not choose a neuro who is unwilling to prescribe oral steriods instead of IV...one caveat: as Erin said, the IV course of treatment is the best choice for Optic Neuritis.

For all other types of flares, I would insist on oral tablets so I could stay home and enjoy my life.
