For Crohn's Disease, Maintenance "I’m 19 and turning 20. I was diagnosed with Crohn’s last March and was taking Pentasa, and it works great, but when I switched to United Healthcare, they wouldn’t cover it. They then prescribed me Apriso. If your Crohn’s is specific to your small intestine and not your colon, please don’t take Apriso. Apriso is meant to target your colon. I went back to the hospital for the third time because of it, so it was decided that I should go back onto Pentasa. It really works for those who aren’t sure about it. It really does. I was in severe pain for months until Pentasa. It’s kept the pain away and let me get back to a normal diet. For those who were on Pentasa and were forced to change medication due to insurance, you can dispute to your insurance that you need it. It took 2 months to do it for me, but it worked out. My insurance now will cover it. Good luck to those with Crohn’s and/or are having trouble finding medication or can’t take Pentasa anymore."

For Crohn's Disease, Maintenance "I am 67 years old and was diagnosed with Crohn's at age 50. I have taken Pentasa for 16 years. I took 4x250 mg three times daily and experienced chest pains. I cut it to 3x250 mg three times daily, and that took care of the chest pains. I am a fairly petite woman, so that could be a factor. I have had flare-ups but generally have done great. I tried cutting back myself, and each time had severe pain, vomiting, etc. I now know not to cut back. I hope to continue on Pentasa."

For Crohn's Disease, Maintenance "The pain I have after eating is relieved if I take my medicine on time. Before this, I was unable to eat any foods without having loose stools and severe pain."
