What is Clomid?
Clomid (clomiphene) is a non-steroidal fertility medicine. It causes the pituitary gland to release hormones needed to stimulate ovulation (the release of an egg from the ovary).
Clomid is used to cause ovulation in women with certain medical conditions (such as polycystic ovary syndrome) that prevent naturally occurring ovulation.
Clomid may also be used for purposes not listed in this medication guide.
Do not use Clomid if you are already pregnant.
You should not use Clomid if you have: liver disease, abnormal vaginal bleeding, an uncontrolled adrenal gland or thyroid disorder, an ovarian cyst (unrelated to polycystic ovary syndrome), or if you are pregnant.

It is not known whether clomiphene passes into breast milk or if it could harm a nursing baby. This medication may slow breast milk production in some women. Tell your doctor if you are breast-feeding a baby.
Using Clomid for longer than 3 treatment cycles may increase your risk of developing an ovarian tumor. Ask your doctor about your specific risk.
Fertility treatment may increase your chance of having multiple births (twins, triplets). These are high-risk pregnancies both for the mother and the babies. Talk to your doctor if you have concerns about this risk.
