Tibolone is an alternative to CC HRT

-licensed for vasomotor, psychological and libido problemds

21
Q

Tibolone risk:benefit ration

-likely due to the anti-oxidant effect of oestrogen

-risk may be lowered by transdermal route/changing progestogen
30
Q

A

Use of oestrogen-only HRT in women with uterus substantially increases the risk of endometrial hyperplasia/carcinoma

Dependent on dose/duration

Risk reduced with sequential HRT and eliminated with CC HRT
