How does this medication work? What will it do for me?
Menotropins are a mixture of naturally-occurring hormones that include follicle stimulating hormone (FSH) and luteinizing hormone (LH). Menotropins are used to help women with certain infertility problems to become pregnant. Menotropins work by stimulating the ovaries to produce eggs.
Menotropins are usually given with human chorionic gonadotropin (hCG). This hormone is also present in this medication. It works similarly to LH and helps to ensure that ovulation occurs at the expected time.

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 chance of blood clot formation, causing a reduction of blood flow to organs or the extremities. If you have a history of clotting, you may be at increased risk of experiencing blood clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg. 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.
If you experience symptoms such as sharp pain and swelling in the leg, difficulty breathing, chest pain, blurred vision or difficulty speaking, contact your doctor immediately.
Lung problems: In rare cases, serious lung problems have been reported with the use of menotropins. Get immediate medical attention if you experience difficulty breathing or wheezing.
Multiple births: Multiple births may occur with fertility medications. 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 bloating and pain 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). 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 any of these symptoms while using this medication, contact your doctor immediately.
Pregnancy: The effect of menotropins on an unborn baby is not known. To avoid the possibility of harm to the baby, menotropins should not be used during pregnancy.
Breast-feeding: It is not known if menotropins pass into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: This medication is intended for use by women of child-bearing age. Its safety and effectiveness have not been established for children.
