How does this medication work? What will it do for me?
Urofollitropin belongs to the class of medications called gonadotropins. It is used to treat infertility in women, when follicle stimulating hormone (FSH) levels are low or as part of assisted reproductive technology procedures such as in-vitro fertilization (IVF). Urofollitropin works by stimulating the ovaries and mimicking the action of FSH, which stimulates eggs to become mature and ready for release by the ovary.
Urofollitropin is usually given in combination with a medication called human chorionic gonadotropin (hCG). This medication causes ovulation to occur by mimicking a natural hormone called luteinizing hormone (LH). Together these medications help women with infertility problems to become pregnant.
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 being given this medication, speak to your doctor. Do not stop using 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 use this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each vial of lyophilized, white to off-white powder or pellet, contains 75 IU of follicle stimulating hormone (FSH), plus 20 mg of lactose as the monohydrate and 0.005 mg tween in a sterile, lyophilized form, for subcutaneous or intramuscular injection. The final product contains sodium phosphate buffer (sodium phosphate dibasic and phosphoric acid). Bravelle contains 1% to 2% luteinizing hormone (LH) activity based on bioassay. Human chorionic gonadotropin (hCG) is not detected in Bravelle. Each vial is available with an accompanying vial of sterile diluent containing 2 mL of 0.9% sodium chloride injection, USP.
How should I use this medication?
The dose of urofollitropin depends on what it is being used for and must be individualized.
For infertility treatment (other than IVF), the usual starting dose is 150 IU daily for the first 5 days of treatment.
For patients undergoing IVF treatment, the usual starting dose is 225 IU daily for the first 5 days of treatment.
In both cases, the response to the medication is determined by blood tests and ultrasound readings. If needed, the dose may be increased to a maximum of 450 IU daily.
The medication should not be used for longer than 12 days in a row.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are receiving the medication without consulting your doctor.
Urofollitropin should only be prescribed by doctors who are experienced in treating fertility problems.
The medication is injected under the skin or into a muscle. Your doctor or other health professional will show you exactly how to mix and draw up the medication into the needles and how to inject it. It is extremely important to understand your treatment and to follow instructions closely. Be sure to ask your doctor any questions you might have.
If you need to use hCG (as determined by lab tests), your doctor will have you inject a dose of hCG one day after your last day of urofollitropin.
Once the dose of medication has been prepared by adding the diluting solution to the powder, it should be used immediately. Discard any unused material after use.
Do not use your injectable solution if it appears cloudy, lumpy, or discoloured.
It is important to use this medication exactly as prescribed and you must visit your doctor on a regular basis to make sure the medication is working properly and that there are no side effects. You will be asked to have blood tests and ultrasounds to test the amount of estrogen in the bloodstream and to determine the size of the follicles.
The unmixed medication should be stored at room temperature, protected from light, and kept out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

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.
Allergic reactions: This medication may cause a serious allergic reaction in some people. If you develop hives, difficulty breathing, or swelling of the face or throat, stop using the medication and seek medical attention immediately.
Blood clots: This medication may increase the chance of blood clot formation, causing a reduction of blood flow to organs or the extremities. Talk to your doctor about the risks and benefits of using this medication. If you experience symptoms of a blood clot (e.g., sharp pain in the muscle of one leg, swelling and warmth of that leg) or a stroke (e.g., confusion, blurred vision, difficulty speaking or moving), seek medical attention immediately.
Kidney problems: If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Lung problems: Rarely, lung problems have been reported by people using this medication. Talk to your doctor about the risks and benefits of using this medication. If you experience any shortness of breath or difficulty breathing, contact your doctor as soon as possible.
Multiple births: Using urofollitropin may result in multiple births (e.g., 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. Most cases do not require treatment, and the condition goes away within 2 to 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). It most often develops after treatment has stopped. 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. If you experience these symptoms while using this medication or shortly after stopping, contact your doctor immediately.
Pregnancy: Women should not use this medication once they have become pregnant.
Breast-feeding: It is not known if this medication passes into breast milk. If you are a breast-feeding mother and are taking urofollitropin, it may affect your baby. This medication should not be used by breast-feeding women.
Children: This medication is intended for use by women of child-bearing age. Its safety and effectiveness have not been established for children.
Seniors: This medication is intended for use by women of child-bearing age. Its safety and effectiveness have not been established for seniors.
