Drugs & Medications

ganirelix subcutaneous




This medication is used as part of a treatment program for certain fertility problems in women. It is generally used in combination with other hormones (FSH and hCG). Ganirelix works by blocking the release of a certain hormone (luteinizing hormone). It helps delay ovulation and increases the chance of producing fertile eggs.

How to use ganirelix subcutaneous

Read the Patient Information Leaflet before starting this medication and each time you get a refill of this medication because new information may be available. You will be trained by a healthcare professional on how to properly use this medication. If any of the information is unclear, consult your healthcare professional.

Inject under the skin (subcutaneously) usually once daily, beginning several days after FSH injection is started, as directed by your doctor. Ganirelix and FSH injections are usually continued until the time of the hCG injection. You will be closely monitored by your doctor, who will determine the right time to discontinue ganirelix and FSH and to give the hCG injection. Follow your doctor's exact instructions on when to start and stop this medication. Discuss your treatment with your doctor if you have any questions.

Wash hands with soap and water before using this medication. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid.

Before injecting each dose, clean the injection site with rubbing alcohol. It is important to change the location of the injection site daily to avoid discomfort or problem areas under the skin.

Inject the prescribed dose as directed by your doctor. Discard any unused portion of the medication immediately after the injection. Do not save it for future use.

Use this medication exactly as directed by your doctor in order to get the most benefit from it. Do not change the dose unless instructed by your doctor or use this medication for a longer period than prescribed.

Side Effects

Redness or pain at the injection site, headache, mild nausea/stomach pain, and tiredness may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if any of these unlikely but serious side effects occur: unusual vaginal bleeding.

This medication may cause a condition known as Ovarian Hyperstimulation Syndrome (OHSS). This condition may occur during therapy and after treatment has been discontinued.
