What is in this leaflet

This leaflet answers some common questions about CRINONE. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you using CRINONE against the benefits this medicine is expected to have for you.
If you have any questions about using this medicine, ask your doctor or pharmacist.

You may need to read it again.

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 (e.g. 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.

How to use CRINONE

CRINONE is applied directly from the applicator deep into the vagina. The applicator is designed to deliver a pre-measured dose of progesterone gel. A small amount of gel will be left in the applicator after usage. Do not be concerned because you will still be receiving the required dose.

How much to use and how often to use it

The amount of CRINONE used depends on the condition being treated.
Your doctor may prescribe one applicator of CRINONE either daily or twice daily and will advise you when to start treatment. If pregnancy occurs treatment may continue for up to 12 weeks or as directed by your doctor.
CRINONE should be used at the same time each day. If used twice a day, one applicator of CRINONE should be used in the morning and the other at night.

How to use CRINONE

Follow these steps carefully or as instructed by your doctor:

1.Wash your hands well with soap and water.

2.Remove the applicator from the sealed wrapper.


4.Hold the applicator by the thick end. Shake down several times like a thermometer to ensure that the contents are at the thin end.

5.The plastic ball in the thin end helps the gel to move down to the tip of the applicator. The ball also helps to control the release of the gel. The applicator is designed so that the ball cannot exit it.

6.Hold the applicator by the flat section of the thick end. Twist off the tab at the thin end of the applicator and discard it.

DO NOT squeeze the thick end while twisting off the tab. This may release gel.

7.Carefully insert the applicator into the vagina while you are in a sitting position or when lying on your back with the knees bent. Gently insert the thin end of the applicator well into the vagina.

8.Squeeze the thick end of the applicator firmly to push the gel into the vagina. Remove the applicator and discard into a waste container. There may be some gel left in the applicator. Do not worry; you will still be receiving the correct dose.

CRINONE coats the vaginal lining to provide long-lasting release of progesterone.
