Nortrel and Lactation
You may use the intrauterine device (IUD) when you are breastfeeding if more than six weeks have passed since you had your baby. If you are breastfeeding, the IUD is not likely to affect the quality or amount of your breast milk or the health of your nursing baby. However, isolated cases of decreased milk production have been reported among women using progestin-only birth control pills.
Nortrel is a prescription medication that is a hormone-releasing system placed in the uterus to prevent pregnancy for up to 5 years. This hormone-releasing system is a type of intrauterine system also know as an intrauterine device (IUD). It is also used to lessen menstrual blood loss in women who have heavy menstrual flow and who also want to use a birth control method that is placed in the uterus to prevent pregnancy. Nortrel belongs to a group of drugs called progestins which change the lining of the uterus, alter cervical mucus, and make it difficult for sperm to enter the uterus.
This medication comes in the form of a plastic device that is inserted by a healthcare provider into the uterus.
Common side effects of Nortrel include irregular menstrual periods, back pain, headache, and nausea.

Why is this medication prescribed?
Nortrel is used to prevent pregnancy after unprotected sexual intercourse (sex without any method of birth control or with a birth control method that failed or was not used properly ). Nortrel should not be used to prevent pregnancy on a regular basis. This medication is to be used as an emergency contraceptive or backup in case regular birth control fails or is used incorrectly. Nortrel is in a class of medications called progestins. It works by preventing the release of an egg from the ovary or preventing fertilization of the egg by sperm (male reproductive cells). It also may work by changing the lining of the uterus (womb) to prevent development of a pregnancy. Nortrel may prevent pregnancy, but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome ) and other sexually transmitted diseases.
