My doctor prescribed Deplin for treatment of depression. In the past, I have tried celexa, lexapro, cymbalta, effexor, elavil, and Wellbutrin. All caused severe side effects. I have IBS, GERD, GAVE (gastric antral vascular ectasia, osteoarthritis, fibromyalgia, hypothyroidism, and mitral valve prolapse. What side effects can Deplin cause?
