I started prednisone today. Was told to take 3 10mg for 3 days, 2 for 3 days then 1 for 3 days. I just started it today but the rash/hives has not subsided. It’s now moving to my neck & face which was not effected before.
Yes you can. They often use both for allergic reactions when you are in a hospital.
I don't know what caused your reaction, but it sometimes takes hours to counteract the spread of a rash.
But do let your doctor know you have added benadryl.
