KAnn,
This was one of the first meds I was put on for my Crohn's way back when I was diagnosed (about
11 years ago). My Crohn's is severe, and this drug is only a mild anti-inflammatory agent, so I was on it for about
a year before we realized it wasn't helping at all. If your arthritis is not too bad, sulfasalazine (aka azulfidine) may help.
What I recall: the pills were round, pretty big and not coated. That made them hard to swallow. Also, you usually have to take a lot of them (between 4-10) each day. Lastly, since they are yellow, they can turn your urine very bright yellow. I have also heard that it can cause your sweat to turn a bit yellow, staining your clothes (just areas of heavy sweating, like pits), and even stain soft contact lenses after awhile...! For me, the urine was the only thing I noticed (not a big deal). I had no other side effects at all.
One last thing, my doctor mentioned that this drug can (but does not always) cause temporary infertility in women (I was 16 at the time and that really didn't matter to me), but your fertility returns to normal shortly after stopping the drug. Just wanted to let you know in case that would matter for you.
Hope it works for you!!
