What is gonadorelin used for?

Gonadorelin is commonly used by women who are missing menstrual periods due to low levels of gonadotropin-releasing hormone (GnRH). It may be used as part of female infertility treatment.

This medication provides a synthetic version of GnRH which is responsible for the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH).

How should I take gonadorelin?

Gonadorelin is injected into a vein or under the skin using an infusion pump, as directed by your doctor. If you are using this medication at home, learn all preparation and usage instructions from your health care professional and the medication package. Follow all instructions for using the infusion pump. Do not mix this medication until you are ready to use it. Before using this medication, check the solution visually for particles or discoloration. If either is present, do not use the solution.

Before each dose, clean the injection site with rubbing alcohol. If you are injecting the medication under the skin, change the injection site as directed by your doctor to lessen injury under the skin. If you are injecting the medication into a vein, you do not need to change the injection site unless directed by your doctor.

The dosage is based on your medical condition and response to treatment. Keep all medical appointments so your doctor can closely monitor your response and adjust your dosage if necessary. Do not change the dose unless directed by your doctor, and do not use this medication for a longer period than prescribed.

Learn how to store and discard medical supplies safely.

Tell your doctor if your condition does not improve.

How do I store gonadorelin?

Most of the time, this medicine will be given in a hospital or doctor’s office. If you store the medication at home, follow the packaging instructions, and keep it out of reach from children and pets.
