Precautions

Drug information provided by: Merative, Micromedex®

It is very important that your doctor check your progress at regular visits while you are using this medicine, to make sure that the medicine is working properly and to check for unwanted effects. Blood and urine tests, semen testing, and ultrasound examinations are needed to check for any unwanted effects caused by this medicine.

Call your doctor right away if you think you have become pregnant while you are using this medicine. You may have a higher risk of an ectopic pregnancy if you get pregnant while undergoing IVF or ICSI procedures. An ectopic pregnancy can be a serious and life-threatening condition. It can also cause problems that may make it harder for you to become pregnant in the future.

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 or tightness, a fast or irregular heartbeat, unusual flushing or warmth of the skin, increased coughing, trouble with breathing, a 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.

For women who are using this medicine:

  • If your doctor has asked you to record your basal body temperature (BBT) each day, make sure that you understand 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), which can be life-threatening. Check with your doctor right away if you have bloating, diarrhea, severe nausea, stomach pain, rapid weight gain, or vomiting.
  • 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 cause serious lung problems (eg, atelectasis or acute respiratory distress syndrome). Check with your doctor right away if you have blue lips, fingernails, or skin, chest tightness, coughing, difficulty or fast breathing, fever, rapid heartbeat, or trouble breathing.
  • 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.
