Clomid (clomiphene)

Prescription only

Antagon (Ganirelix)

Prescription only
Helps women to ovulate and get pregnant.

Clomid (clomiphene) works well for women who cannot get pregnant because they are not ovulating.

Helps women become pregnant through in-vitro fertilization.

Antagon (Ganirelix) will have less overall injections compared to alternative medications, but your doctor will help you decide the best protocol and options for you.

Upsides
  • One of the few fertility medicines available as a pill rather than injection.
  • Available as a generic product and is less costly than other fertility medicines.
  • Effective for women who are not ovulating or have a condition called polycystic ovary syndrome.
  • A protocol that uses Antagon (Ganirelix) will be shorter and will have overall less injections than other options.
  • Comes as a pre-packaged kit, so it's easy to set up and use. The syringes are already premixed.
  • Can be used in women who have liver or kidney problems.
Downsides
  • A pelvic exam and pregnancy test are necessary before each use of Clomid (clomiphene).
  • Not a good option if you have issues with your liver.
  • Not safe for women with ovarian cysts or enlarged ovaries (aside from polycystic ovary syndrome).
  • Not safe for long-term use. Your doctor will only prescribe Clomid (clomiphene) for a very short time period.
  • Only available as an injection that must be given for several consecutive days.
  • Must be given along with other fertility treatments, so it's not the only medicine you'll receive.
