if surgery what to give before?
For fibroids less than 3 cm, the medical management is the same as with heavy menstrual bleeding:
Mirena coil (1st line) – fibroids must be less than 3cm with no distortion of the uterus or COCP / NSAIDs
For fibroids more than 3 cm, women need referral to gynaecology for medical vs surgical tx
GnRH agonists reduce the size of the uterus prior to surgery
