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.
