Oral mesalamine not breaking down?

After my insurance denied canasa supplements for my UP, the GI told me to take 1.2mg of lialda every morning. This morning I passed one almost whole! The outer layer was gone but it was a hard, long, very obvious pill. Is this common? Do I let my GI know or should I wait? I've just been worried the pills wouldn't last "in transit" long enough to do me any good, and now I'm nervous they aren't actually breaking down, especially as my eyes are getting red, itchy and watery. I don't want this spreading! Any advice? Similar stories?

I wouldn't worry unless the pills are passing and look exactly like when you took them (with orange/red coating complete) on a regular basis.
