Metrodin (urofollitropin for injection) is a gonadotropin used to stimulate follicular development and the induction of ovulation in patients with polycystic ovary syndrome, and infertility, who have failed to respond or conceive following adequate clomiphene citrate therapy. Metrodin and hCG may also be used to stimulate the development of multiple follicles in ovulatory patients undergoing Assisted Reproductive Technologies (ART) such as in vitro fertilization. The brand name Metrodin is discontinued, but generic versions may be available. Common side effects of Metrodin (urofollitropin for injection) include:

  • breast tenderness
  • nausea
  • vomiting
  • abdominal pain or cramps
  • bloating
  • diarrhea
  • headache
  • hot flashes
  • injection site reactions (pain, rash, swelling, redness, or irritation)
  • fever
  • chills
  • muscle or joint aches
  • headache, and
  • fatigue.

The dose of Metrodin to stimulate development of the follicle is individualized for each patient. Metrodin may interact with other drugs. Tell your doctor all medications and supplements you use. Metrodin is not recommended for use during pregnancy. It may harm a fetus. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.
