Treating Multiple Sclerosis With IV Steroids Medications such as Solu-Medrol and Decadron are potent steroids that ease inflammation and are often used to treat an acute attack of multiple sclerosis.

During an acute attack of multiple sclerosis -- also called exacerbations or relapses -- there is a distinct increase in the severity of symptoms. The onset of the attack may take several days or weeks. New symptoms may appear, or your existing symptoms (such as numbness, tingling, slurred speech, or blurred vision) may flare up or worsen.

When attacks occur, you may receive Solu-Medrol or Decadron at a treatment center each day for one to five days, depending on your treatment plan.
