<s>[INST] Hi I think I may be allergic to Harissa, I am definitely allergic to horseradish. However I am concerned that Prozac may have been causing me to have frequent stomach upsets. I hope not because I was hoping to be rid of a recent depressive phase. Can you advise. [/INST] Hi, You should understand that virtually any medicine can cause stomach upset. Depending upon the type of stomach upset, we can attribute it to whether that specific medication causes that particular side effect. In your case, you have not mentioned what type of upset you have. Prozac is an anti-depressant medication. It can cause a wide variety of side effects including stomach problems. Most common are vomiting, indigestion, loose motion and nausea. So if you can't tolerate the medicine, consult the doctor who have started the medication. He may change the dosage or change the medication. Hope I have answered your question. Let me know if I can assist you further.  </s>
