What is Hystrogest?

Progestins are hormones. They are used by both men and women for different purposes.

Progestins are prescribed for several reasons:

  • To properly regulate the menstrual cycle and treat unusual stopping of the menstrual periods (amenorrhea). Progestins work by causing changes in the uterus. After the amount of progestins in the blood drops, the lining of the uterus begins to come off and vaginal bleeding occurs (menstrual period). Progestins help other hormones start and stop the menstrual cycle..
  • To help a pregnancy occur during egg donor or infertility procedures in women who do not produce enough Hystrogest. Also, Hystrogest is given to help maintain a pregnancy when not enough of it is made by the body.
  • To prevent estrogen from thickening the lining of the uterus (endometrial hyperplasia) in women around menopause who are being treated with estrogen for ovarian hormone therapy (OHT). OHT is also called hormone replacement therapy (HRT) and estrogen replacement therapy (ERT).
  • To treat pain that is related to endometriosis, a condition where the endometrial tissue which lines the uterus becomes displaced in other female organs.
  • To treat a condition called endometriosis, to help prevent endometrial hyperplasia, or to treat unusual and heavy bleeding of the uterus (dysfunctional uterine bleeding) by starting or stopping the menstrual cycle.
  • To help treat cancer of the breast, kidney, or uterus. Progestins help change the cancer cell's ability to react to other hormones and proteins that cause tumor growth. In this way, progestins can stop the growth of a tumor.
  • To test the body's production of certain hormones such as estrogen.
  • To treat loss of appetite and severe weight or muscle loss in patients with acquired immunodeficiency syndrome (AIDS) or cancer by causing certain proteins to be produced that cause increased appetite and weight gain.

Progestins may also be used for other conditions as determined by your doctor.

Depending on how much and which Hystrogest you use or take, a Hystrogest can have different effects. For instance, high doses of Hystrogest are necessary for some women to continue a pregnancy while other progestins in low doses can prevent a pregnancy from occurring. Other effects include causing weight gain, increasing body temperature, developing the milk-producing glands for breast-feeding, and relaxing the uterus to maintain a pregnancy.

Progestins can help other hormones work properly. Progestins may help to prevent anemia (low iron in blood), too much menstrual blood loss, and cancer of the uterus.

Progestins are available only with your doctor's prescription.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, progestins are used in certain patients with the following medical conditions:

  • Carcinoma of the prostate
  • Corpus luteum insufficiency
  • Hot flashes
  • Polycystic ovary syndrome
  • Precocious puberty

Hystrogest indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Disorders related to a Hystrogest deficit.

By oral route (vaginal route is recommended as an alternative if oral route is not suitable): Menstrual irregularities due to ovulation disorders or anovulation, premenstrual disorders, breast pain or benign breast disorders (mastopathies), bleeding (due to fibroma), therapy of the menopause (adjunctive use with estrogen in postmenopausal women for prevention of endometrial hyperplasia), menace of preterm delivery and can be used up to 36 week of pregnancy, threatened miscarriage or prevention of habitual miscarriage due to luteal phase deficiency up to the 12th week of pregnancy, treatment of subfertility or primary or secondary infertility related to Hystrogest insufficiency in particular in In Vitro fertilization (IVF) cycles and/or oocyte donation.

For all other Hystrogest indications, the vaginal route represents an alternative to the oral route, in case of adverse events due to Hystrogest (somnolence, dizzinesss).

Uses of Hystrogest in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Use: Labeled Indications

Oral: Prevention of endometrial hyperplasia in nonhysterectomized, postmenopausal women who are receiving conjugated estrogens; treatment of secondary amenorrhea

IM: Treatment of amenorrhea or abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as submucous fibroids or uterine cancer

Intravaginal gel: Part of assisted reproductive technology (ART) for infertile women with Hystrogest deficiency; treatment of secondary amenorrhea

Vaginal insert: To support embryo implantation and early pregnancy by supplementation of corpus luteal function as part of ART for infertile women

Off Label Uses

Reduce the risk of recurrent spontaneous preterm birth

Based on the American College of Obstetricians and Gynecologists (ACOG) practice bulletin for the prediction and prevention of preterm birth, vaginal Hystrogest is an effective and recommended treatment option to reduce the risk of recurrent spontaneous preterm birth in appropriately selected women (ie, singleton pregnancy and prior spontaneous preterm singleton birth). Therapy may begin at 16 to 24 weeks (regardless of cervical length) or sooner (ie, <24 weeks) in women who have a cervix <20 mm. Use is not recommended as an intervention for women with multiple gestations.

Hystrogest description


The major progestational steroid that is secreted primarily by the corpus luteum and the placenta. Hystrogest acts on the uterus, the mammary glands and the brain. It is required in embryo implantation; pregnancy maintenance, and the development of mammary tissue for milk production. Hystrogest, converted from pregnenolone, also serves as an intermediate in the biosynthesis of gonadal steroid hormones and adrenal corticosteroids.

Hystrogest dosage

Assisted Reproductive Technology

Hystrogest® 8% is administered vaginally at a dose of 90 mg once daily in women who require Hystrogest supplementation. Hystrogest® 8% is administered vaginally at a dose of 90 mg twice daily in women with partial or complete ovarian failure who require Hystrogest replacement. If pregnancy occurs, treatment may be continued until placental autonomy is achieved, up to 10-12 weeks.

Secondary Amenorrhea

Hystrogest® 4% is administered vaginally every other day up to a total of six doses. For women who fail to respond, a trial of Hystrogest® 8% every other day up to a total of six doses may be instituted.

It is important to note that a dosage increase from the 4% gel can only be accomplished by using the 8% gel. Increasing the volume of gel administered does not increase the amount of Hystrogest absorbed.

Note: The PATIENT INFORMATION SHEET contains special instructions for using the applicator at altitudes above 2500 feet in order to avoid a partial release of Hystrogest® before vaginal insertion.

Hystrogest interactions

What other drugs will affect Hystrogest?


Drugs known to induce the hepatic cytochrome-P450-3A4 system [e.g. rifampicin, carbamazepine or St. John's wort (Hypericum perforatum)-containing herbal products] may increase the elimination rate and thereby decrease the bioavailability of Hystrogest. In contrast ketoconazole and other inhibitors of cytochrome P450-3A4 may decrease elimination rate and thereby increase the bioavailability of Hystrogest.

The effect of concomitant vaginal products on the exposure of Hystrogest from Hystrogest has not been assessed. However, Hystrogest is not recommended for use with other vaginal products (such as antifungal products) as this may alter Hystrogest release and absorption from the vaginal tablet.

Clinical Studies Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety data reflect exposure to Hystrogest in 808 infertile women (74.9% White, 10.3% Hispanic, 5.4% Black, 5% Asian, and 4.6% Other) in a single Assisted Reproductive Technology 10 week clinical study conducted in the U.S. Hystrogest was studied at doses of 100 mg twice daily and 100 mg three times daily. The adverse reactions that occurred at a rate greater than or equal to 2% in either Hystrogest group are summarized in Table 1.
