Gonal-f RFF Redi-ject

Generic name: follitropin alfa (subcutaneous route)

Medically reviewed by  A Ras MD.

What is Gonal-f RFF Redi-ject?

Gonal-f RFF Redi-ject is an injection Pen that delivers a prescription medicine containing follicle-stimulating hormone (FSH) used in infertile women to help healthy ovaries develop (mature) and release an egg, cause your ovaries to make multiple (more than 1) eggs as part of an Assisted Reproductive Technology (ART) program



Gonal-f® RFF Redi-ject® contains human follicle stimulating hormone (hFSH), a glycoprotein hormone manufactured by recombinant DNA technology. The active drug substance, follitropin alfa, has a dimeric structure consisting of two non-covalently linked, non-identical glycoproteins designated as the α-and β-subunits. The α-and β-subunits have 92 and 111 amino acids, respectively, and their primary and tertiary structures are indistinguishable from those of human follicle stimulating hormone.

Recombinant human FSH production occurs in genetically modified Chinese Hamster Ovary (CHO) cells cultured in bioreactors. Purification by immunochromatography using an antibody specifically binding FSH results in a highly purified preparation with a consistent FSH isoform profile, and a high specific activity. The protein content is assessed by size exclusion high pressure liquid chromatography.

The biological activity of follitropin alfa is determined by measuring the increase in ovary weight in female rats. The in vivo biological activity of follitropin alfa has been calibrated against the first International Standard for recombinant human follicle stimulating hormone established in 1995 by the Expert Committee on Biological Standards of the World Health Organization. Gonal-f® RFF Redi-ject® contains no luteinizing hormone (LH) activity. Based on available data derived from physico-chemical tests and bioassays, follitropin alfa and follitropin beta, another recombinant follicle stimulating hormone product, are indistinguishable.

Gonal-f® RFF Redi-ject® is a disposable, prefilled drug delivery system intended for the subcutaneous injection of multiple and variable doses of a liquid formulation of follitropin alfa.

Each Gonal-f® RFF Redi-ject® is filled with 415 International Units (30 mcg), 568 International Units (41 mcg), or 1026 International Units (75 mcg) follitropin alfa to deliver at least 300 International Units (22 mcg) in 0.5 mL, 450 International Units (33 mcg) in 0.75 mL, or 900 International Units (66 mcg) in 1.5 mL, respectively. Each Redi-ject® also contains 60 mg/mL sucrose, 3.0 mg/mL m-cresol, 1.1 mg/mL di-sodium hydrogen phosphate dihydrate, 0.45 mg/mL sodium dihydrogen phosphate monohydrate, 0.1 mg/mL methionine, 0.1 mg/mL Poloxamer 188. O-phosphoric acid and/or sodium hydroxide may be used for pH adjustment.

Under current storage conditions, Gonal-f® RFF Redi-ject® may contain up to 10% of oxidized follitropin alfa.

Therapeutic Class: Infertility

Mechanism of Action

Follicle stimulating hormone (FSH), the active component in Gonal-f® RFF Redi-ject®, is required for normal follicular growth, follicular maturation, and gonadal steroid production. The level of FSH is critical for the onset and duration of follicular development, and consequently for the timing and number of follicles reaching maturity.

Gonal-f® RFF Redi-ject® stimulates ovarian follicular growth in women who do not have primary ovarian failure. In order to effect the final phase of follicle maturation, resumption of meiosis, and rupture of the follicle in the absence of an endogenous LH surge, human chorionic gonadotropin (hCG) must be given following treatment with Gonal-f® RFF Redi-ject® when monitoring of the woman indicates that appropriate follicular development parameters have been achieved. There is inter-woman variability in response to FSH administration.

Who should not use Gonal-f RFF Redi-ject?

  • are allergic to recombinant human FSH or any of the ingredients in Gonal-f RFF Redi-ject. See the end of this leaflet for a complete list of ingredients in Gonal-f RFF Redi-ject.
  • have ovaries that no longer make eggs (primary ovarian failure)
  • are pregnant or think you may be pregnant
  • have uncontrolled thyroid or adrenal problems
  • have a tumor in your female organs, including your ovaries, breast, or uterus that may get worse with high levels of estrogen
  • have a tumor in your brain, such as a tumor in your pituitary or hypothalamus
  • have abnormal bleeding from your uterus or vagina
  • have ovarian cysts or large ovaries, not due to polycystic ovary syndrome (PCOS)

What should I tell my healthcare provider before using Gonal-f RFF Redi-ject?

Before you use Gonal-f RFF Redi-ject, tell your healthcare provider if you:

  • have or have had asthma
  • have been told by a healthcare provider that you have an increased risk for blood clots (thrombosis)
  • have ever had a blood clot (thrombosis), or anyone in your family has ever had a blood clot (thrombosis)

What are the possible side effects of Gonal-f RFF Redi-ject?

Gonal-f RFF Redi-ject may cause serious side effects, including:

  • severe allergic reactions. Women who have used Gonal-f, Gonal-f RFF, or Gonal-f RFF Redi-ject in the past may have a severe allergic reaction right away when they use Gonal-f RFF Redi-ject again. This severe allergic reaction may lead to death. If you have any of the following symptoms of a severe allergic reaction, stop using Gonal-f RFF Redi-ject and go to the hospital right away:
    • shortness of breath
    • swelling of your face
    • itchy, red bumps or rash on your skin (hives)
  • ovaries that are too large. Gonal-f RFF Redi-ject may cause your ovaries to be abnormally large. Symptoms of large ovaries include bloating or pain in your lower stomach (pelvic) area.
  • ovarian hyperstimulation syndrome (OHSS). Using Gonal-f RFF Redi-ject may cause OHSS. OHSS is a serious medical condition that can happen when your ovaries produce too many eggs (overstimulated). OHSS can cause fluid to suddenly build up in the area of your stomach, chest, and heart, and can cause blood clots to form. In rare cases OHSS has caused death. OHSS may also happen after you stop using Gonal-f RFF Redi-ject. Stop using Gonal-f RFF Redi-ject and call your healthcare provider right away if you have symptoms of OHSS, including:
    • trouble breathing
    • severe lower stomach (pelvic) area pain
    • decreased urine output
    • nausea
    • vomiting
    • weight gain
    • diarrhea
  • lung problems. Gonal-f RFF Redi-ject may cause serious lung problems including fluid in your lungs (atelectasis), trouble breathing (acute respiratory distress syndrome), and worsening of asthma.
  • blood clots. Gonal-f RFF Redi-ject may increase your chance of having blood clots in your blood vessels. Blood clots can cause:
    • blood vessel problems (thrombophlebitis)
    • stroke
    • loss of your arm or leg
    • blood clot in your lung (pulmonary embolus)
  • twisting (torsion) of your ovary. Gonal-f RFF Redi-ject may increase the chance of your ovary twisting if you already have certain conditions such as OHSS, pregnancy and previous abdominal surgery. Twisting of your ovary may lead to blood flow being cut off to your ovary.
  • pregnancy with and birth of multiple babies. Gonal-f RFF Redi-ject may increase your chance of having a pregnancy with more than 1 baby. Having a pregnancy and giving birth to more than 1 baby at a time increases the health risk for you and your babies. Your healthcare provider should tell you about your chances of multiple births.
  • birth defects. A baby born after an ART cycle may have an increased chance of having birth defects. Your chances of having a baby with birth defects may increase depending on:
    • your age
    • certain sperm problems
    • your genetic background and that of your partner
    • a pregnancy with more than 1 baby at a time
  • ectopic pregnancy (pregnancy outside your womb). Gonal-f RFF Redi-ject may increase your chance of having a pregnancy that is abnormally outside of your womb. Your chance of having a pregnancy outside of your womb is increased if you also have fallopian tube problems.
  • miscarriage. Your chance of loss of an early pregnancy may be increased if you had difficulty becoming pregnant.
  • tumors of the ovary. If you have used medicines like Gonal-f RFF Redi-ject more than 1 time to get pregnant, you may have an increased chance of having tumors in your ovary(ies) (including cancer).

The most common side effects of Gonal-f RFF Redi-ject include:

  • headache
  • stomach pain
  • stomach bloating
  • bruising at the injection site
  • nausea
