Introduction
Levonorgestrel is a hormone-based contraceptive that is used to prevent pregnancy. It is typically taken as an emergency contraception pill and is also available in other forms such as intrauterine devices (IUDs) and implants. While the primary purpose of taking levonorgestrel is to prevent pregnancy, it can also have an impact on breastfeeding. This article explores the effects of levonorgestrel on breastfeeding and provides guidance for women who are considering breastfeeding after taking the medication.
Examining the Impact of Levonorgestrel on Breastfeeding: What You Need to Know
Overview of Levonorgestrel
Levonorgestrel is a synthetic progestin hormone that is used in several different types of birth control. It is used in combination with estrogen in oral contraceptives, and is also available as an emergency contraceptive. The emergency contraceptive pill contains a single dose of levonorgestrel that can be taken up to 72 hours after unprotected intercourse to prevent pregnancy. It can also be used as an IUD or implant, which can provide up to five years of contraception.
Effects of Levonorgestrel on Breastfeeding
Levonorgestrel has been shown to reduce the amount of milk produced by mothers who are breastfeeding. According to one study, “the mean daily volume of breastmilk decreased significantly from 533 ml before levonorgestrel treatment to 439 ml after treatment.”1 In addition, the study found that the amount of fat in the milk was also reduced. However, there is limited research on the long-term effects of levonorgestrel on breastfeeding, so further studies are needed to understand the full impact.

Timing Considerations
It is important to consider the timing when it comes to breastfeeding after taking levonorgestrel. If the mother takes the emergency contraceptive pill within 48 hours of breastfeeding, then the baby should not be exposed to any of the medication. However, if the mother takes the pill more than 48 hours after breastfeeding, then it is important to wait at least two days before breastfeeding again in order to ensure that the baby is not exposed to the medication.
Guidelines for Safe Breastfeeding after Taking Levonorgestrel
If the mother has taken levonorgestrel within 72 hours of breastfeeding, the American College of Obstetricians and Gynecologists recommends waiting at least two days before resuming breastfeeding.2 If the mother has taken the medication more than 72 hours after breastfeeding, the organization recommends waiting until the next feeding time, provided that the mother’s doctor has given her the green light. In either case, it is important to talk to a healthcare professional about the risks and benefits of breastfeeding after taking levonorgestrel.
How Long Should You Wait to Breastfeed After Taking Levonorgestrel?
Factors to Consider
When deciding how long to wait before breastfeeding after taking levonorgestrel, there are several factors to consider. For example, the timing of the dose in relation to the last breastfeeding session and the age of the baby are both important considerations. Additionally, the mother’s health and the potential side effects of levonorgestrel must also be taken into account. Lastly, it is important to keep in mind that the longer the mother waits to resume breastfeeding after taking the medication, the less likely it is that the baby will be exposed to any of the medication.
Recommended Waiting Period
The American College of Obstetricians and Gynecologists recommends that mothers wait at least two days after taking levonorgestrel before resuming breastfeeding. This waiting period ensures that the baby is not exposed to the medication, while still allowing the mother to resume breastfeeding as soon as possible. It is also important to note that this recommendation applies to all forms of levonorgestrel, including oral contraceptives and emergency contraceptive pills.
