I'm guessing we are all a little different but here's what I found on your question while you wait for members with experience to respond.

"Official answer. After taking a dose of a Methylprednisolone tablet it should be out of your system after approximately 13 to 20 hours. Methylprednisolone tablets have an elimination half-life of approximately 2.5 hours to 3.5 hours. This is the time it takes for the drug levels in your plasma to reduce by half."
