Uses for Gonal-F RFF Redi-ject

Follitropin alfa is a hormone that is the same as follicle-stimulating hormone (FSH) made by the pituitary gland. FSH helps develop eggs in the ovaries.

Follitropin alfa injection is used as a fertility medicine to help develop eggs in women who have difficulty becoming pregnant due to ovulation problems. Additionally, many women trying to get pregnant will use this medicine while participating in a fertility program called assisted reproductive technology (ART). ART includes procedures such as in vitro fertilization (IVF) or embryo transfer (ET). Follitropin alfa may be used along with other medicines for these purposes.

Follitropin alfa injection is also used as a fertility medicine to assist men with low sperm counts in producing more sperm. Treatment with human chorionic gonadotropin should be done before starting follitropin alfa. This pretreatment raises the testosterone level to the correct amount. Treatment with human chorionic gonadotropin should continue while follitropin alfa is being used.

Some patients may receive another hormone called gonadotropin-releasing hormone agonist (GnRHa) before beginning treatment with follitropin alfa. GnRHa lowers the amount of FSH released from the pituitary gland. This allows the doctor to replace the FSH with the right amount of follitropin alfa each day to achieve fertility.

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

Precautions while using Gonal-F RFF Redi-ject

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

If you are a woman who can get pregnant, your doctor may do tests to ensure you are not pregnant before starting treatment. Call your doctor right away if you think you might be 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. It can also cause problems that may make it harder for you to become pregnant in the future.

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 cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while using this medicine.

This medicine may increase your risk of having problems with the ovaries including twisting or enlargement of the ovaries, or 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 cause serious lung problems (e.g., atelectasis, acute respiratory distress syndrome, or asthma). Check with your doctor right away if you have blue lips, fingernails, or skin, coughing, difficulty or fast breathing, fever, rapid heartbeat, tightness in the chest, 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 or tightness, a fast or irregular heartbeat, unusual flushing or warmth of the skin, increased coughing, trouble breathing, sudden difficulty 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 receive it more than once to get pregnant. Talk to your doctor about this risk.
