AKT-4409

A 45-year-old patient with a history of rheumatoid arthritis is currently taking sulfasalazine, paracetamol, and ibuprofen for their condition. They have been experiencing low mood and have tried non-pharmaceutical interventions with little success. The patient now reports that their depressive symptoms are worsening, prompting the GP to consider starting them on an antidepressant.

Which antidepressant would pose the highest risk of causing a GI bleed in this patient, necessitating the use of a proton pump inhibitor as a precautionary measure?
