How does this medication work? What will it do for me?
Follitropin delta belongs to the class of medications called gonadotropins. It is a synthetic hormone similar to the human hormone called follicle stimulating hormone (FSH), a hormone produced by the pituitary gland that helps eggs mature and become ready for release by the ovaries.
Follitropin delta works by helping to stimulate the development of eggs in the ovaries. It is used by women having assisted reproductive technology (ART) procedures (e.g., in-vitro fertilization) in fertility clinics.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each 1 mL of clear, sterile solution for injection contains 33.3 mg of follitropin delta. Nonmedicinal ingredients: phenol, polysorbate 20, L-methionine, sodium sulfate decahydrate, disodium hydrogen phosphate dodecahydrate, phosphoric acid, sodium hydroxide and water for injections.
How should I use this medication?
The recommended starting dose of follitropin delta is based on body weight, and the level of a hormone in your body called anti-Müllerian hormone (AMH). Your doctor will calculate the starting dose. After the first cycle of treatment, your doctor will adjust the dose based on how well your ovaries responded to the previous cycle. This medication is injected subcutaneously (under the skin), once daily, starting 2 or 3 days after menstrual bleeding begins. Your doctor will monitor for follicle development with ultrasounds or blood tests. Once an appropriate number of follicles have matured, follitropin delta is stopped and another medication, human chorionic gonadotropin (hCG) will be given to cause ovulation.
If you are injecting this medication yourself, your doctor or nurse will show you how to use this medication properly.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Blood clots: This medication may increase the risk of forming blood clots, especially if you are already at risk of blood clots. Risk factors for blood clots include being severely overweight and having a personal or family history of blood clots. However, pregnancy itself can also increase the risk of a blood clot.
Ectopic pregnancies: This medication may increase the risk of having an ectopic pregnancy (where the baby develops in one of the fallopian tubes instead of the uterus). It is important to have an early ultrasound to make sure that the baby is developing inside the uterus.
Lung Problems: The use of other gonadotropin medications for fertility treatment has been associated with breathing problems. This can include flare-ups of asthma symptoms, fluid collecting in the lungs, making it difficult to breathe, or a collapsed lung. If you experience any difficulty breathing while you are using follitropin delta or after it has been stopped, contact your doctor as soon as possible.
Multiple births: This medication may increase the risk of multiple births (mostly twins). Talk to your doctor about the risks of multiple births before beginning treatment.
Ovarian enlargement: Some women using this medication may experience ovarian enlargement associated with abdominal bloating or pain. In most cases, the pain and bloating stop without treatment within 2 or 3 weeks. If you experience these symptoms, contact your doctor.
Ovarian hyperstimulation syndrome (OHSS): Treatment with this medication can cause a condition called ovarian hyperstimulation syndrome (OHSS). With OHSS, too many follicles grow and cause abdominal or pelvic discomfort or pain, nausea, vomiting, and weight gain. Some women may experience difficulty breathing, diarrhea, and decreased urination. OHSS can progress rapidly and may become serious. It can occur even after treatment has stopped. If you experience any of these symptoms, contact your doctor immediately.
Pregnancy: This medication should not be used by pregnant women. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication should not be used by breast-feeding women.
Children: This medication is intended for use by people of child-bearing age. Its safety and effectiveness have not been established for children.
