I had been prescribed celexa for my anxieyy. I had been taking 20 mg a day for almost three weeks. I had developed terrible diarrhea after about 1 week and a half after starting celexa. I didn't notice any benefit for aiding in my anxiety but the diarrhea has been so bad that I stopped taking it. It's been 3 days since I stopped taking it but the diarrhea hasn't stopped. I'm way more miserable now than I was before as my anxiety is off the charts worrying about the diarrhea! I have an appt with the dr in 4 days but I was hoping for some answers before then. Has anyone else had to deal with this horrible side effect?
