Tom, I think your friend was referring to cortisone acetate 5 mg. I think it is a stronger form than the cortef pills if I remember what i was told once. as far as i habe heard, Cortef is Cortef ( two of the 5 mg pills is the same as 1 of the 10 mg pills) Has anyone heard anything different or does someone else know more about what cortisone acetate is.
