They usually start you out with high doses via IV then taper the dose down orally.

That's what they told me happened this time. The uti caused me to feel like a relapse.

Oh, yes, many times. I unfortunately have a lot of urinary tract infections and, for a long time, would have pseudo-relapses every time. Oddly, the MS caused the nerves in my bladder to stop working, so I have self catheterized for about 12 years. For whatever reason, I haven't had an infection since and haven't had a pseudo-infection, either! Thank the Lord for small favors!

When I've had a couple of relapses I had I steroids. The rest of the time, I had oral prednisone. I really didn't notice any difference and the efficacy of the two. The taper is extremely important, however, and if your doctor does not order one insist upon getting one.

I've had both. Really bad flares, I go for 5 days of IV solumedrol, followed by a prednisone taper so you aren't jerked off the steroids all at once. That's rough. If you get solumedrol and your Dr doesn't order the taper, ask for it. Sometimes I get a 16 day prednisone treatment if the flare isn't too bad.
