What CRINONE is used for

CRINONE is a vaginal gel that contains natural progesterone.

Progesterone is a hormone that is produced by the ovaries during the second half of the menstrual cycle.

It is an essential hormone for preparing the uterus (womb) for pregnancy and on-going support of pregnancy.

The lack of normal progesterone production by the ovaries in the second half of the menstrual cycle is called luteal phase defect. Women who have this defect may have difficulties in becoming pregnant and may have a higher risk of miscarriage.

CRINONE is used to supplement progesterone in women who have luteal phase defect. CRINONE is also used to supplement or replace your own natural progesterone in Assisted Reproductive Technology procedures (eg IVF).

Your doctor may have prescribed CRINONE for another purpose.

Ask your doctor if you have any questions why CRINONE has been prescribed for you.

This medicine is available only with a doctor's prescription.

CRINONE is not addictive.
