Indications

Stage B2-C Prostatic Carcinoma: Goserelin is used together with flutamide to manage locally confined Stage T2b-T4 (Stage B2-C) carcinoma of the prostate. The Goserelin and flutamide treatment should start 8 weeks before radiation therapy begins, and it continues during the radiation therapy. Prostatic Carcinoma: Goserelin is used in the palliative treatment of advanced carcinoma of the prostate. Endometriosis: Goserelin is used to manage endometriosis, including pain relief and reduction of endometriotic lesions for as long as the therapy lasts. Experience with Goserelin for endometriosis is limited to women aged 18 years and older who were treated for 6 months. Endometrial Thinning: Goserelin is used as an endometrial-thinning agent before endometrial ablation for dysfunctional uterine bleeding. Advanced Breast Cancer: Goserelin is used in the palliative treatment of advanced breast cancer in pre- and perimenopausal women. The estrogen and progesterone receptor values may help predict whether Goserelin therapy is likely to be beneficial. The syringe also has an automatic safety feature that helps prevent needlestick injury.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Goserelin is a synthetic decapeptide analogue of GnRH. When it's given in its biodegradable formulation, it acts as an inhibitor of pituitary gonadotropin secretion. In animal and in vitro studies, goserelin caused regression or inhibited the growth of two hormonally sensitive tumours: the dimethylbenzanthracene (DMBA)-induced rat mammary tumour and the Dunning R3327 prostate tumour.

Pregnancy & Breastfeeding

Goserelin should not be used during pregnancy, with one exception: palliative treatment of advanced breast cancer. There are no adequate and well-controlled studies of goserelin in pregnant women. But based on how it works in humans, and on the increased pregnancy loss seen in animal studies, goserelin can harm the baby when given to a pregnant woman. If it is used during pregnancy, the patient should be told about the possible danger to the baby. The hormone changes expected with goserelin treatment also raise the risk of pregnancy loss.

In rats and rabbits, goserelin crosses the placenta after subcutaneous administration. When pregnant rats and rabbits were given goserelin during organogenesis, there was more preimplantation loss and more resorptions. Pregnant rats that received goserelin throughout gestation and lactation had more umbilical hernia in their offspring, and the increase was related to the dose. Other reproduction studies in rats showed that goserelin lowered the survival of fetuses and pups. The animal data available were not enough to calculate human dose or exposure multiples.

It is not known whether goserelin passes into human milk. It does pass into the milk of lactating rats. Many drugs are excreted in human milk, and goserelin could cause serious adverse reactions in nursing infants. So a decision should be made either to stop nursing or to stop the drug, taking into account how important the drug is to the mother.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: Goserelin 3.6 mg is given under the skin (subcutaneously) every 28 days, into the front wall of the abdomen below the navel line. A doctor should supervise it, and an aseptic technique must be used. A delay of a few days is allowed, but every effort should be made to keep to the 28-day schedule. Stage B2-C Prostatic Carcinoma When Goserelin is given together with radiotherapy and flutamide for patients with Stage T2b-T4 (Stage B2-C) prostatic carcinoma, treatment should start 8 weeks before radiotherapy begins and carry on during the radiation therapy. One option is a Goserelin 3.6 mg depot 8 weeks before radiotherapy, followed 28 days later by the Goserelin 10.8 mg depot. The other option is four injections of the 3.6 mg depot at 28-day intervals, with two depots before radiotherapy and two during it. Prostatic Carcinoma For advanced prostate cancer, Goserelin is meant for long-term use unless it is clinically inappropriate. Endometriosis For endometriosis, the recommended duration of treatment is 6 months. There are no clinical data on treating benign gynecological conditions with Goserelin for longer than 6 months. Retreatment cannot be recommended for endometriosis, because no safety data for retreatment are available. If symptoms come back after a course of therapy and further Goserelin treatment is being considered, bone mineral density should be monitored. Clinical studies suggest that adding Hormone Replacement Therapy (estrogens and/or progestins) to Goserelin reduces the bone mineral loss that happens with Goserelin alone. It does this without reducing how well Goserelin relieves the symptoms of endometriosis. Hormone Replacement Therapy may also reduce vasomotor symptoms and vaginal dryness linked to hypoestrogenism. The best drugs, dose and duration of this treatment have not been established. Endometrial Thinning When Goserelin is used to thin the endometrium before endometrial ablation, the recommended dose is one or two depots, given four weeks apart. If one depot is given, surgery should be done at four weeks. If two depots are given, surgery should be done within two to four weeks after the second depot. Breast Cancer For advanced breast cancer, Goserelin is meant for long-term use unless it is clinically inappropriate. Renal or Hepatic Impairment No dose adjustment is needed for patients with renal or hepatic impairment. Goserelin 10.8 mg is given under the skin (subcutaneously) every 12 weeks, into the front wall of the abdomen below the navel line. A doctor should supervise it, and an aseptic technique must be used. A delay of a few days is allowed, but every effort should be made to keep to the 12-week schedule. Stage B2-C Prostatic Carcinoma When Goserelin is given together with radiotherapy and flutamide for patients with Stage T2b-T4 (Stage B2-C) prostatic carcinoma, treatment should start 8 weeks before radiotherapy begins and carry on during the radiation therapy. The regimen is one Goserelin 3.6 mg depot, followed 28 days later by one Goserelin 10.8 mg depot. Prostatic Carcinoma For advanced prostate cancer, Goserelin is meant for long-term use unless it is clinically inappropriate. Renal or Hepatic Impairment No dose adjustment is needed for patients with renal or hepatic impairment. Women Goserelin 10.8 mg implant is not indicated in women, because the data are not enough to support reliable suppression of serum estradiol. Female patients who need goserelin should be treated according to the prescribing information for the Goserelin 3.6 mg implant.
