Will i have withdrawals from taking the first six pills together(started late)of a medrol (methylprednisolone) 4mg pack today? the pills made me feel very itchy.

Not expected: Allergy to oral Medrol (methylprednisolone) is rare if existent at all. Since it takes about 6 hours before noticeable effects can be observed, I question that Medrol (methylprednisolone) is the actual culprit. However if subsequent dosing again leads to itching, then you will need to stop taking it and ask your doctor to provide a substitute.
