Infliximab (IFX) is a chimeric monoclonal antibody biologic drug that works against tumor necrosis factor alpha (TNF-α) and is used to treat autoimmune diseases. This is case of a 45year old female patient who had suicidal thoughts after receiving infusions with IFX. She did not report any family psychiatric history. She was diagnosed with ulcerative colitis. She had many relapses and she was treated with azathioprine and prednisolone. After many incidents of diarrhea, she started therapy with infliximab infusions. She had totally 13 infusions during a period of 13 months. The last year and in particular during the time of Infliximab intake, she reported suicidal ideation. Due to lack of improvement in her physical symptoms, she voluntarily discontinued medication and resorted to a nutritionist and a mental health counselor, where she followed cognitive and behavioral interventions. Treatment of autoimmune disorders with infliximab raise an awareness among medical and paramedical staff involved in the care of these patients about the psychiatric side effects of the drug.
