Generic Name: clomiphene (KLOE mih feen)
Brand Names: Clomid, Serophene
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.
Before taking this medicine
You should not use Clomid if you are allergic to clomiphene, or if you have:
abnormal vaginal bleeding;
an ovarian cyst that is not related to polycystic ovary syndrome;
past or present liver disease;
a tumor of your pituitary gland;
an untreated or uncontrolled problem with your thyroid or adrenal gland; or
if you are pregnant.
To make sure Clomid is safe for you, tell your doctor if you have:
endometriosis or uterine fibroids.
Do not use Clomid if you are already pregnant. Talk to your doctor if you have concerns about the possible effects of Clomid on a new pregnancy.
Clomiphene can pass into breast milk and may 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.
How should I take Clomid?
Use Clomid exactly as directed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Your doctor will perform medical tests to make sure you do not have conditions that would prevent you from safely using Clomid.
Clomid is usually taken for 5 days, starting on the 5th day of your menstrual period. Follow your doctor's instructions.
You will need to have a pelvic examination before each treatment cycle. You must remain under the care of a doctor while you are using Clomid.
You will most likely ovulate within 5 to 10 days after you take Clomid. To improve your chance of becoming pregnant, you should have sexual intercourse while you are ovulating.
Your doctor may have you take your temperature each morning and record your daily readings on a chart. This will help you determine when you can expect ovulation to occur.
In most cases, Clomid should not be used for more than 3 treatment cycles.
If ovulation occurs but you do not get pregnant after 3 treatment cycles, your doctor may stop treatment and evaluate your infertility further.
Store at room temperature away from moisture, heat, and light.
