What is clomiphene used for?
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).
Clomiphene is used to cause ovulation in women with certain medical conditions (such as polycystic ovary syndrome) that prevent naturally occurring ovulation.
Clomiphene may also be used for purposes not listed in this medication guide.
How should I take clomiphene?
Use clomiphene 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 clomiphene.
Clomiphene 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 this medicine.
You will most likely ovulate within 5 to 10 days after you take clomiphene. 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, clomiphene 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.
How do I store clomiphene?
Clomiphene is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store clomiphene in the bathroom or the freezer. There may be different brands of clomiphene that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.
You should not flush clomiphene down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
