i just started taking celexa last friday. i've read that it (along with other SSRIs) can increase the chances of upper GI bleeding. should i be worried about it causing further rectal bleeding if i'm currently in a flare-up? the whole reason i finally gave in to trying an anxiety med was that i was starting to believe that my constant anxiety was keeping my colon from fully healing. it would be ironic if it turned out to be the other way around. thanks!
