The Estradiol Implant is one of a group of medicines called hormone replacement therapy (HRT). It's used for problems that may affect some women when their body no longer produces oestrogen (for example after their change of life (or menopause)). It's also used to prevent bones becoming brittle (osteoporosis) if you are unable to use other treatments.

Preventing brittle bones
Too little oestrogen may also cause brittle bones (osteoporosis). As you get older, the bones become porous, which means they become brittle and break more easily.
If you are at an increased risk of fractures due to osteoporosis (thinning of the bones) but are unable to take other treatments or if other therapies prove to be ineffective, HRT may also be used for this purpose.  Your doctor should discuss all the available options with you.
