A 20-year-old woman presents with a positive pregnancy test and is diagnosed with an ectopic pregnancy after ruling out an intrauterine pregnancy. She is asymptomatic and her serum beta-human chorionic gonadotropin (B-hCG) level is 877 IU/L. A transvaginal ultrasound shows a 24mm adnexal mass without a heartbeat and no free fluid in the abdomen. Although expectant management is an option, she declines. What is the recommended initial treatment?
