Crinone 4% and Crinone 8%
(progesterone gel)
For Vaginal Use Only

Please read this information carefully before you start to use Crinone and each time your prescription is renewed, in case anything has changed. This leaflet does not take the place of discussions with your doctor. If you still have any questions, ask your doctor or health-care provider.

What is Crinone?

Crinone is medicine that contains the female hormone called progesterone.

What is Crinone used for?

  • Crinone 4% and Crinone 8% are used to treat the absence of a menstrual period in a woman who has previously had a menstrual period. Progesterone is one of the hormones that allows women to have regular menstrual periods. When you do not produce enough progesterone, menstrual irregularities can occur. Crinone may be prescribed to increase your progesterone.
  • Crinone 8% is also used as part of a program for women who are undergoing fertility treatments to get pregnant. Progesterone is one of the hormones that helps to prepare the lining of your uterus so that it is ready to receive and nourish a fertilized egg and to continue a pregnancy. If you are undergoing ART treatment and your doctor has determined your body does not produce enough progesterone on its own, Crinone may be prescribed to increase your progesterone.
  • If pregnancy occurs, Crinone may be supplemented for 10-12 weeks until production of progesterone by the placenta is adequate.

Who should not use Crinone?

Do not start using Crinone if you:

  • Are allergic to progesterone, progesterone-like drugs, or any of the inactive ingredients in the gel (ask a pharmacist if you are not sure about the inactive ingredients in Crinone).
  • Have unusual vaginal bleeding which has not been evaluated by a doctor.
  • Have or have had a liver disease.
  • Have or have had cancer of the breast or genital organs.
  • Have had a miscarriage and your physician suspects some tissue is still in the uterus.
  • Have or have had blood clots in the legs, lungs, eyes, or elsewhere.

What are the possible side effects of Crinone?

Serious side effects include:

  • Blood clots. Progestational drug products may increase your chance of having blood clots in your blood vessels. Blood clots can cause:
  • Birth defects. Abdominal wall defect and cleft palate have been reported with Crinone use in early pregnancy. It is not known if these defects were caused by Crinone.

Call your healthcare provider right away if you get any of the following warning signs or any other unusual symptoms that concern you:

  • Pains in the calves or chest, a sudden shortness of breath or coughing blood indicating possible clots in the legs, heart, or lungs.
  • Severe headache or vomiting, dizziness, faintness, or changes in vision or speech, weakness or numbness of an arm or leg indicating possible clots in the brain or eye.

Common side effects include:

  • abdominal pain
  • perineal pain (the perineum is the area between the vagina and the rectum)
  • cramps
  • bloating
  • headache
  • fatigue
  • increased appetite
  • constipation
  • diarrhea
  • nausea
  • joint pain
  • depression
  • mood swings
  • sleep disorder
  • nervousness
  • decreased libido
  • breast enlargement
  • excessive urination at night
  • vaginal discharge
  • upper respiratory tract infection

These are not all the possible side effects of Crinone. For more information, ask your healthcare provider or pharmacist for advice about side effects.
