How long does it take steroid epidural side effects to go away?

Can take up to. 3-4 weeks generally. Speak with your doctor to determine if something can be done to help you with your side effects.
A few days. Typically, side effects from epidural steroids go away after a few days. Occasionally, I have seen them for 7-10 days. It is important for you to contact your physician if they last for longer than that. The most common side effects are facial flushing, irritability, low fever, and headache.
