CLOMIPHENE (KLOE mi feen) treats irregular or absent ovulation in people trying to get pregnant. It works by helping your body produce an egg (ovulation), which increases the chance of pregnancy.

Take this medication by mouth with a glass of water. Follow the directions on the prescription label. Take exactly as directed for the exact number of days prescribed. Take your doses at regular intervals. Most women take this medication for a 5-day period, but the length of treatment may be adjusted. Your care team will give you a start date for this medication and will give you instructions on proper use. Do not take your medication more often than directed.

Talk to your care team about the use of this medication in children. Special care may be needed.

Side effects that you should report to your care team as soon as possible:

• Allergic reactions—skin rash, itching, hives, swelling of the face, lips, tongue, or throat
• Change in vision
• Ovarian hyperstimulation syndrome—stomach or pelvic pain, bloating, nausea, vomiting, diarrhea, weight gain
• Pancreatitis—severe stomach pain that spreads to your back or gets worse after eating or when touched, fever, nausea, vomiting

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

Make sure you understand how and when to use this medication. You need to know when you are ovulating and when to have sexual intercourse. This will increase the chance of a pregnancy.

Visit your care team for regular checks on your progress. You may need tests to check the hormone levels in your blood or you may have to use home-urine tests to check for ovulation. Try to keep any appointments.

Compared to other fertility treatments, this medication does not greatly increase your chances of having multiple babies. An increased chance of having twins may occur in roughly 5 out of every 100 women who take this medication.

Stop taking this medication at once and contact your care team if you think you are pregnant.

This medication is not for long-term use. Most women that benefit from this medication do so within the first three cycles (months). Your care team will monitor your condition. This medication is usually used for a total of 6 cycles of treatment.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medication affects you. Do not stand or sit up quickly. This reduces the risk of dizzy or fainting spells.

Drinking alcoholic beverages or smoking tobacco may decrease your chance of becoming pregnant. Limit or stop alcohol and tobacco use during your fertility treatments.
