Uses for Fertinex

Urofollitropin injection is used to treat infertility in women. This medicine is a synthetic hormone called follicle-stimulating hormone (FSH). FSH is made by the pituitary gland in the body. FSH helps to develop eggs in women's ovaries.

Urofollitropin will help develop and release eggs in women who have trouble becoming pregnant due to ovulation problems and have already received a medicine to manage their pituitary gland.

This medicine is also used for women with healthy ovaries who are part of a fertility program known as assisted reproductive technology (ART). ART includes procedures like in vitro fertilization (IVF). Urofollitropin is used along with human chorionic gonadotropin (hCG) in these procedures.

Urofollitropin is often used in women who have low levels of FSH and high levels of LH. Women with polycystic ovary syndrome typically have these hormone levels and are treated with urofollitropin to compensate for the low FSH. Many women treated with urofollitropin have already tried clomiphene (eg, Serophene) and have not been able to conceive. Urofollitropin may also be used to stimulate the ovaries to produce multiple follicles, which can then be collected for gamete intrafallopian transfer (GIFT) or in vitro fertilization (IVF).

This medicine is available only with your doctor's prescription.

Call your doctor right away if you think you have become pregnant while using this medicine. You may have a higher risk of an ectopic pregnancy or miscarriage if you get pregnant while undergoing IVF procedures. An ectopic pregnancy can be a serious and life-threatening condition.

This medicine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention.

If your doctor has asked you to record your basal body temperature (BBT) daily, make sure you know how to do this. Carefully follow your doctor's instructions.

This medicine may increase your risk of having a problem with the ovaries called ovarian hyperstimulation syndrome (OHSS). OHSS is a serious problem that can be life-threatening. Call your doctor right away if you have severe pain in the lower stomach area, nausea, vomiting, weight gain, diarrhea, decreased urine output, or trouble breathing.

This medicine may increase your risk of having a blood clot, heart attack, or stroke. This is more likely in people who already have heart disease. Contact your doctor right away if you have chest pain, tightness in the chest, a fast or irregular heartbeat, unusual flushing or warmth of the skin, increased coughing, trouble with breathing, sudden difficulty with breathing at night, or abnormal swelling in your ankles or legs. These could be symptoms of serious heart problems or blood clots.

This medicine may cause more than one egg to be released from your ovary at the same time. This means you may become pregnant with more than one baby. Talk with your doctor about this possibility before you start using this medicine.

This medicine may increase your risk of having ovarian cancer if you received it more than one time to get pregnant. Talk to your doctor about this risk.
