I have been taking Zoloft for 8 years for anxiety, stemming from menopause. I've been having discomfort in my upper right quadrant under my ribs for about 6 years. My doctor diagnosed IBS and I've been taking donnatal, which helps. I've recently decided to taper off of the Zoloft and have noticed that my discomfort has diminished. Could it have been associated with taking the Zoloft?
