No it's a steroid. Won't help at all
Wouldn't think prednisone would be a good option.. But I know that clonidine (a blood pressure med) is often prescribed for withdrawal. Also meds like Xanax can be used to treat the associated anxiety short term during wds but must be used with caution as it can be addictive and for me can cause mood swings. The clonidine however is not addictive. Ask your doc what meds might be helpful to you during wds.
Have you had any tests which indicate that your cortisol is low? Prednisone has serious side effects & withdrawals of its own & is not a med to be taken casually.
Best wishes.
