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.
3. DO NOT REMOVE THE TWIST-OFF TAB AT THIS TIME.
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.
