Pregnyl

Generic Name: chorionic gonadotropin (KORE-ee-ON-ik goe-NAD-oh-troe-pin)
Brand Name: Examples include Novarel and Pregnyl

Pregnyl is used for:

Treating fertility problems in certain women who have not gone through menopause. Treating certain testicular development problems and stimulating the development of secondary sexual characteristics in certain patients. It is also used to treat boys 4 to 9 years old who have testicles that have not moved into the scrotum.

Pregnyl is a hormone. Human chorionic gonadotropin (HCG) stimulates cells in the testicles to produce androgens and in the ovaries to produce progesterone. Androgens cause the development of male secondary sexual characteristics (eg, hair growth, deepening voice) and may cause the testicles to drop. HCG acts like luteinizing hormone (LH) by stimulating ovulation (release of an egg) in women.

Do NOT use Pregnyl if:

  • you are allergic to any ingredient in Pregnyl
  • you have androgen (male sex hormone)-dependent tumors, prostate cancer, an active blood clot, brain lesions, unexplained uterine or genital bleeding, an enlarged ovary or ovarian cysts, or an enlargement or tumor of the pituitary gland
  • you are experiencing abnormally early puberty
  • you are pregnant

Contact your doctor or health care provider right away if any of these apply to you.

How to use Pregnyl:

Use Pregnyl as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Pregnyl is usually administered as an injection at your doctor's office, hospital, or clinic. If you are using Pregnyl at home, carefully follow the injection procedures taught to you by your health care provider.
  • If Pregnyl contains particles or is discolored, or if the vial is cracked or damaged in any way, do not use it.
  • Using the technique described to you by your doctor, add the diluent to the vial that contains the medicine. Mix the solution by gently rotating the vial. DO NOT SHAKE. The solution should be clear and free of particles.
  • Wipe the rubber stopper of the vial with an alcohol swab. Insert the needle straight through the center circle of the rubber stopper. Draw up the solution for injection. After drawing up the solution, switch needles. Be sure all air bubbles are tapped out of the syringe.
  • Wipe the appropriate injection site (usually the upper thigh or buttocks) with an alcohol swab, then insert the syringe. To be sure that the needle is not in a vein, pull back on the plunger of the syringe while holding the syringe in place. If the syringe begins to fill with blood, the needle is in a vein. If this happens, remove the needle from the skin, throw the syringe away, and start the procedure again using new materials (drugs, syringes, etc.).
  • After giving the injection, cover the injection site with a small bandage if necessary.
  • Keep this product, as well as syringes and needles, out of the reach of children. Do not reuse needles, syringes, or other materials. Dispose of properly after use. Ask your doctor or pharmacist to explain local regulations for proper disposal.
  • If you miss a dose of Pregnyl, contact your doctor right away.

Ask your health care provider any questions you may have about how to use Pregnyl.
