ulipristal (emergency contraception)
Ulipristal belongs to the class of medications called selective progesterone receptor modulators. It works by disrupting the way the hormone progesterone works in the body.
It is used as an emergency contraceptive, when it is taken within 120 hours (5 days) of having unprotected sexual intercourse, or it is believed that a contraceptive has failed.
This medication is believed to prevent pregnancy by preventing or delaying ovulation, depending on the stage of the woman’s menstrual cycle. It may also prevent implantation of the egg by altering the endometrium (inner lining of the uterus). It is important to realize that once implantation has occurred and pregnancy is established, ulipristal cannot cause an abortion or harm the fetus. No serious complications have been reported with this medication.
This medication is intended for use only by women whose regular birth control methods have failed or who may have had intercourse without birth control. It is not a substitute for correct use of regular birth control.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
Each white-to-off-white, round, curved tablet marked with “ella” on both sides, contains ulipristal acetate 30 mg. Nonmedicinal ingredients: lactose monohydrate, povidone K-30, croscarmellose sodium and magnesium stearate.
The recommended dose of ulipristal is one 30 mg tablet taken as soon as possible within 5 days after unprotected sexual intercourse or contraceptive failure.
Because this medication is often associated with nausea, your doctor may also want you to take medication to prevent nausea at the same time you take ulipristal. If you vomit within three hours of taking ulipristal, contact your doctor immediately, as you will need to take a second tablet. This medication can be used at any time during the menstrual cycle. It can be taken with or without food. Taking it with food may help reduce nausea.
Most women have their expected menstrual period within 7 days of their normal time after using this medication. If you don't have your menstrual period within 7 days of when it is expected, you should have a pregnancy test done.
