My fiancé is having difficulty getting his insurance company to cover Pentasa. He has been a pentasa for a couple of years but it's a new insurance company and they suck. They want him to try all the medications they cover before they give him Pentasa. So, his choices are Humira or sulfasalazine. If his doctor says it's ok and his insurance company agrees then that's what he will try first. Has anyone every taken it? Opinion?
