About Susten 200 Capsule
Susten 200 Capsule contains Progesterone 200 mg. Natural micronised progesterone is a hormone medicine identical to the progesterone made by the ovaries. It is used to support early pregnancy and fertility treatment, to treat some menstrual problems, and with oestrogen in hormone replacement therapy. Your doctor will tell you whether to take it by mouth or place it in the vagina.

How to use
Use it exactly as your doctor prescribed. If taking by mouth, swallow the capsule whole with water, usually at bedtime. If your doctor has told you to use it vaginally, wash your hands and insert the capsule deep into the vagina. Do not stop it on your own, especially during pregnancy.
How it works
Progesterone acts on the lining of the womb to make it ready for and able to support a pregnancy. It also balances the effects of oestrogen on the womb lining.
