I have Rheumatoid Arthritis and have been taking this drug for 1 year now with no problems. Rheumy has just reduced it to 200gms per day from 200. Cobined with Sulfasalazine, I am now in remission.
Just remember to limit time under the sun and make sure your Doctor has you having eye tests once a year at least. You need to get a baseline eye test when you begin this drug.
Good luck and I hope Hydroxy helps you!
