Q

What is the treatment for pelvic inflammatory disease?

A

Parenteral cephalosporin + Oral doxycyclin

Adjunct metronidazole

Think: Pelvis or vagina can get fungal infections which have spores, so cephalosporin.
You also use your pelvis to ride a bicycle, so doxycycline
Pelvis has a hole, like metronidahole
