Clomiphene is used to induce ovulation (egg production) in women who do not produce ova (eggs) but wish to become pregnant (infertility). Clomiphene is in a class of medications called ovulatory stimulants. It works similarly to estrogen, a female hormone that causes eggs to develop in the ovaries and be released.

Clomiphene comes as a tablet to take by mouth. It is usually taken once a day for 5 days, beginning on or about day 5 of the cycle. To help you remember to take clomiphene, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take clomiphene exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Keep all appointments with your doctor and laboratory. Your doctor may order certain lab tests to check your body’s response to clomiphene.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
