Product Description


SUPREFACT (buserelin acetate) is indicated for:

Nasal solution:

  • The palliative treatment (maintenance treatment) of patients with hormone-dependent advanced carcinoma of the prostate gland (Stage D).
  • The treatment of endometriosis in patients who do not require surgery as primary therapy. The duration of treatment is usually six months and should not exceed nine months.


  • SUPREFACT is contraindicated in patients who are hypersensitive to this drug, to any ingredient in the formulation or component of the container. Isolated cases of anaphylaxis have been reported.
  • SUPREFACT is also contraindicated in patients with prostate cancer who do not present with hormone-dependent carcinoma and in patients who have undergone orchiectomy.
  • SUPREFACT is contraindicated in women who are pregnant. As with other LHRH agonists, it is not known whether SUPREFACT causes fetal abnormalities in humans. Women of childbearing potential should be carefully examined before treatment to exclude pregnancy (see WARNINGS AND PRECAUTIONS, Special Populations – Pregnant Women).
  • The use of SUPREFACT in women who are breast-feeding is contraindicated.
  • SUPREFACT should not be administered to females having undiagnosed abnormal vaginal bleeding


SUPREFACT should be prescribed by a qualified physician experienced in the use of hormonal therapy in endometriosis and prostate cancer, SUPREFACT nasal solution should be administered under the supervision of a healthcare professional.


The adverse effects observed in patients treated with SUPREFACT are, principally, directly related to its anticipated pharmacologic action, i.e. suppression of pituitary (gonadotropin) and gonadal (testosterone or estradiol) hormone production with resulting clinical signs and symptoms of hypogonadism. The most frequent adverse events reported in patients with prostatic cancer receiving SUPREFACT are hot flushes, loss of libido, impotence, nasal irritation (nasal solution) and headache (nasal solution).


Prostate Cancer

Men with advanced prostate cancer often have no symptoms. Advanced prostate cancer can be found by x-rays or tests done for other medical reasons. When there are symptoms, they depend on the size of the new growth and where cancer has spread. For example, when prostate cancer has spread to the pelvic bones, you may feel lower back or hip pain. You may have no symptoms of cancer in the prostate. Or you may have problems urinating or see blood in your urine. When men do have symptoms, they often feel tired or weak, have lost weight, feel pain, or have shortness of breath.

Prostate cancer spreads when cancer cells break free from the prostate. These cells enter the bloodstream or lymph nodes. Most cancer cells that break free from the prostate die. But sometimes they spread to other organs and start new tumors. Advanced prostate cancer often moves into the bones before spreading to other organs. Sometimes it spreads to the lungs or liver. It can also spread to the brain.

To diagnose advanced cancer, your health care provider looks for cancer outside the prostate. Blood and imaging tests may show where cancer has spread. Your health care provider will want to know how much cancer there is and how it is affecting you. That way they can offer treatment that is best for you.

Advanced cancer may be found before, at the same time, or later than the main tumor. Most men diagnosed with advanced prostate cancer have had biopsy and treatment in the past. When a new tumor is found in someone who has been treated for cancer in the past, it is usually cancer that has spread. Rarely, tests done for other reasons may reveal prostate cancer cells.


Endometriosis is an often painful disorder in which tissue similar to the tissue that normally lines the inside of the uterus — the endometrium — grows outside the uterus. Endometriosis most commonly involves the ovaries, fallopian tubes and the tissue lining the pelvis. Rarely, endometrial tissue may spread beyond pelvic organs.

With endometriosis, the endometrial-like tissue acts as endometrial tissue would — it thickens, breaks down and bleeds with each menstrual cycle. But because this tissue has no way to exit the body, it becomes trapped. When endometriosis involves the ovaries, cysts called endometriomas may form. Surrounding tissue can become irritated, eventually developing scar tissue and adhesions — abnormal bands of fibrous tissue that can cause pelvic tissues and organs to stick to each other.

Endometriosis can cause pain — sometimes severe — especially during menstrual periods. Fertility problems also may develop. Fortunately, effective treatments are available.
