A 48-year-old woman with a 2-year history of rheumatoid arthritis presents to A&E

A 48-year-old woman with a 2-year history of rheumatoid arthritis presents to A&E with a cut to her finger that would not stop bleeding. She reports feeling generally tired and weak and feels like she’s had cold sores around her lips for much longer than usual. Her blood tests reveal white blood cell count of 1.3 x 10⁹ /L (normal range 4-11 x 10⁹ /L), hemoglobin of 71g/L (normal range 115-160g/l) and platelet concentration of 115 x 10⁹ /L (normal range 150- 400 x 10⁹/L). On questioning, she recalls being treated with trimethoprim for a urinary tract infection 2 weeks ago. Which drug is she most likely being treated on for her RA?
