This medication is used to treat infertility in women. It works by stimulating an increase in the amount of hormones that support the growth and release of a mature egg (ovulation). This medication is not recommended for women whose ovaries no longer make eggs properly (primary pituitary or ovarian failure).
Clomiphene must be taken by mouth exactly as directed by your doctor in order to be most effective. It is important to follow your dosing schedule carefully.
Your dosage is based on your medical condition and response to therapy. Do not take it more often or for a longer time than prescribed by your doctor. Long-term treatment with this medication is not recommended and should not be more than 6 cycles.
You may be directed to record your body temperature, perform ovulation tests, and properly time sexual intercourse for best results. Ask your doctor if you have any questions.
Stomach upset, bloating, abdominal/pelvic fullness, flushing ("hot flashes"), breast tenderness, headache, or dizziness may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Tell your doctor immediately if any of the following occur: vision problems/changes, eye pain.
Tell your doctor immediately if any of these unlikely but serious side effects occur: abnormal vaginal bleeding, mental/mood changes.
