The primary treatment for chronic endometritis is antibiotics, tailored to the specific pathogen identified. Commonly used antibiotics include doxycycline, metronidazole, and ciprofloxacin. Treatment duration usually spans 10-14 days. In cases where the infection is related to retained products of conception or intrauterine devices (IUDs), surgical intervention such as dilation and curettage (D&C) may be necessary.
