According to your symptoms (sweating, stomach cramps, and diarrhea) you may be experiencing either a side effect from the therapy or a type of gastro-intestinal infection. Plaquentil (an anti-inflammatory drug) and Celexa (an antidepressant) can cause gastrointestinal symptoms similar to the ones you describe. However, an intestinal infection must first be confirmed/excluded and that’s why a microbiological examination of a fecal sample is necessary to identify the infective agent (if there is one). If diarrhea is not caused by anintestinal infection then the drugs you are taking are probably the reason for this condition. A helicobacter pillory-infection can be confirmed with serological blood examinations but that is not needed in your case because a helicobacter pillory doesn’t cause diarrhea. It can only cause inflammation of the stomach’s mucosa; it is indicates peptic ulcer development. In the case of a negative microbiological report (no infection), you may consult a psychiatrist and a rheumatologist for further activities (increasing the dose or changing the drugs). In case of a positive microbiological report (there is infection), you may consult an infectologist.
