*Please note that ACOG recommends prophylactic antibiotics for HSG and PID:
Postoperative pelvic inflammatory disease is an uncommon but potentially serious complication in patients undergoing hysterosalpingography. Patients with dilated fallopian tubes at the time of the procedure are at greater risk than patients with non-dilated tubes. Antibiotic prophylaxis is not recommended for patients with no history of pelvic infection. If the procedure demonstrates dilated fallopian tubes, 100 mg of doxycycline may be given twice daily for five days. In patients with a history of pelvic infection, doxycycline can be administered before the procedure and continued if dilated fallopian tubes are found.
