6 reviews for Progesterone (Prometrium)
Prometrium contains Progesterone.
Progesterone is a natural female hormone. As capsules, it is used with oestrogen in HRT to protect the womb lining, and to bring on periods when they have stopped.
It is also used in fertility treatment and in some pregnancies to support the womb lining, under specialist care.
What is it used for?
- Protecting the womb lining in women taking oestrogen HRT
- Missing periods (amenorrhoea)
- Fertility treatment and pregnancy support (specialist use)
How does it work?
Progesterone prepares and maintains the womb lining, and balances the effect of oestrogen on the womb.
