View instructions on how to administer Crinone®.

CRINONE® is a smooth white to off-white gel filled into vaginal applicators for single use.

Each applicator contains a slightly larger amount of gel than actually released, as the rest of the product tends to adhere to the inside of the applicator. It is therefore quite normal for a little gel to be left inside the applicator. Each applicator contains 1.45 g vaginal gel and is designed in such way that with each administration an exactly defined amount of gel (1.125 g) is delivered. Any content of gel remaining in the applicator after use must be discarded.

Crinone® is available at a strength of 90 mg/dose (8% gel) progesteroneprogesteronea hormone produced by the corpus luteum during the second half of a woman's menstrual cycle; it thickens the lining of the uterus to prepare it to accept implantation of a fertilized egg (note that mg stands for milligrams which is a unit measure).[1]

Crinone® is available in packages of 6 or 18 applicators. [1]

One application of Crinone® 8% (90 mg of progesteroneprogesteronea hormone produced by the corpus luteum during the second half of a woman's menstrual cycle; it thickens the lining of the uterus to prepare it to accept implantation of a fertilized egg) is used every day, starting the day of the embryoembryoa fertilized egg that has begun cell division transfer. In some cases, the dose can be increased to two applications of Crinone® 8% daily. If pregnancy occurs, treatment should be continued for up to 10 to 12 weeks. [1]

Crinone® is to be applied directly from the specially designed applicator into the vagina.

Crinone® (Progesterone gel) is used for luteal phase support in induced cycles such as In Vitro Fertilization (IVFin vitro fertilization (IVF)a procedure by which eggs produced by administering fertility drugs are retrieved from a woman's body and fertilized by sperm in a laboratory, and the resulting embryos are transferred by catheter to the uterus) cycles including oocyte donation recipients with or without functional ovaries.
