i have crohn;s and have been in flare for almost a year (i know. crazy right) i was put on humira after the asacol made me feel awful once i was taken off the entocort. the humira made me REALLY REALLY SICK and still, 3 mos later, feel worse now than i did before i started taking it. a couple weeks ago the doc put me back on asacol and entocort.
anyways... about 2 mos ago my skin started getting really REALLY bad. it's never been nice (i'm 21 and it got bad at 10) but it hasn't been this bad since i was 14. i have multiple cistic pimples on my chin, some on my forhead. regular zits on my chin and forhead and a lot of black heads. i even got pimples on my back (by my neck) and on my shoulders and rarely got any there before. less than 1 like every other month. i started thinking it was either those meds, or the round of the humira. OR, if it could possibly be the crohn's its self. i started using the burts bees spot treat. it's in their "natural acne solutions" line. i figured i'd give it a shot. but i just started tonight so i don't know how it's going to work.
but to get rid of the mild stuff i had before it got worse, i tried proactiv, diferin and clindagel, purpose, plain dove, dial, panoxyl, you name it... i tried it. and nothing worked. find a sympathtic derm, or play around. i personally think proactiv is a waste (except for their sulfer mask) b/c all it is is benzoyal peroxide. so find something at the drug store with the same % and try that. everything else in proactive is just filler. if the drug store stuff doesn't work, find a stronger one and if that doesn't work, the proactiv def. wouldn't. a derm can proscribe stronger ones.
Prednisone can cause acne. I had UC for ten years until I perforated and had my colon removed and a J-pouch built 16 years ago. My son has UC and moved onto the Imuran last year. He did have some acne with the prednisone too. He has been in a wonderful remission this past year and is so enjoying feeling healthy. The only change he continues to make is to leave dairy alone as he realizes he is lacto intolerant. I hope you will get the same success. How I wish this was available to me back when I was ill. Hang in there. I would strongly recommend the Proactive acne products you can buy on TV or the net. They can really help to clear it up.
