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 reduction of blood flow to organs or the extremities. You are at higher risk of developing blood clots if you are over 35 years of age, have a history of blood clots, or have a close family member who has experienced blood clots. If you experience pain in the chest or leg, unexplained shortness of breath, fast and irregular heartbeat, severe headache, blurred vision, or slurred speech, get immediate medical attention. Talk to your doctor about the risks and benefits of using this medication.
Ectopic pregnancies: This medication may increase the risk of having an ectopic pregnancy (i.e., the baby develops in one of the fallopian tubes instead of in the uterus). It is important to have an early ultrasound to ensure that the baby is developing inside the uterus.
Instructions: It is extremely important to understand your treatment and to follow instructions closely. Be sure to ask your doctor any questions you might have.
Lung problems: Rarely, this medication can cause problems with the lungs. Get immediate medical attention if you experience wheezing or difficulty breathing.
Multiple births: This medication may increase the risk of 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. 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). 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.
Porphyria: If you have a porphyria, a rare condition that affects the production of heme in the body, 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.
Pregnancy: This medication should not be used during pregnancy.
Breast-feeding: It is not known if this medication passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. This medication should not be used while breast-feeding.
