Methotrexate Administration to Patients With Presumed Ectopic Pregnancy Leads to Methotrexate Exposure of Intrauterine Pregnancies

Abstract

Most patients with suspected EP who are eligible for medical treatment lack definitive sonographic features of EP. Treatment with MTX in such cases should be delayed, as clinically reasonable, to improve the diagnosis and prevent inadvertent administration of MTX to patients with a viable IUP.
