I've just been restarted on Mesalazine for my IBD since having an ileostomy. I have been prescribed two 800mg modified release tablets which I take in the morning with food. I've noticed on two occasions that around 4 hours later these tablet appear completely intact in my stoma bag. They obviously aren't serving any pharmacological purpose at all! Has anyone else experienced pills just passing straight through and if so did a doctor find a solution. I'm aware that Mesalazine is available in a granular form but I don't know if this would be better. Any insights would be most welcome.
