Gonapeptyl – Triptorelin uses, dose and side effects


0.1 mg / ml injection solution

1. What Gonapeptyl is and what it is used for

This medicine is supplied as a syringe in a single-use syringe. It is given as an injection under the skin in the lower abdomen.

This medicine contains triptorelin, a chemically produced equivalent of the natural hormone et GnRH (gonadotropin-releasing hormone ). GnRH regulates the secretion of sex hormones in the body (so-called gonadotropins ): luteinizing hormone ( LH ) and follicle-stimulating hormone ( FSH ). Gonapeptyl blocks the effect of GnRH. This reduces the levels of LH and FSH (so-called down-regulation). This prevents premature ovulation.

This medicine is used to treat women in assisted reproduction (ART). In assisted reproduction, ovulation sometimes occurs prematurely, and then the chance of pregnancy decreases. GONAPEPTYL is used for downregulation and prevention of premature LH – release, which could cause such premature ovulation.

Triptorelin contained in Gonapeptyl may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

3. How to use Gonapeptyl

The recommended dose is an injection under the skin in the lower abdomen once a day. Treatment can be started on days 2-3 or days 21-23 of the menstrual cycle (or 5-7 days before the expected menstruation). After 2-4 weeks, you will receive other hormones to stimulate follicle growth (egg sac growth). In general, Gonapeptyl treatment is continued until the follicles have reached the appropriate size. This normally takes 4-7 weeks.

When there are enough egg sacs, you will receive a single injection of a drug called human chorionic gonadotropin ( hCG ) to induce ovulation.

The doctor will closely monitor events in at least 2 weeks after hCG – injection one.


If the clinic has asked you to inject the medicine yourself, follow the instructions given to them.
