Cathie thank you for your info. I think i am going to wait a little longer and see if acne jus goes away. I also think prednisone has some effect on hormones, since it also makes body hair grow. I was on antibiotics for almost a year (tetracycline), they didn't help much. Besides the neuro told me it is not a good idea to take antibiotics if you just been put IVIG. He said i could get a urinary infection. I have no idea why but that's what he said. i think the hormone approach is bette (taking contraceptives). What do you think?
