I would switch back to Asacol, asap. It's very suspicious that hardly anything comes up when you Google Teva 5-ASA and I've never heard of anyone taking it (and I'm on this forum a lot...). Definitely ask your doctor about
this.
Did you have any of these symptoms before you switched to the Teva 5 ASA?
BTW -- I've heard many complaints about Teva's generic version of wellbutrin...apparently it doesn't work the same way as the brand name or other generic versions.
