October 11, 2025 •

4 min read

According to the European Medicines Agency, some lactation-suppressing medications, like bromocriptine, are no longer recommended for routine use due to safety concerns, meaning other methods and safer medications must be considered. Finding the right approach, including knowing what medication is used to stop breastfeeding milk, requires careful consideration of both medical and natural methods to ensure safety and comfort.

Quick Summary

This guide explores prescription and alternative methods for stopping breast milk production. It details the pharmacology of lactation suppressants like cabergoline and bromocriptine, discusses non-medication strategies, and compares the effectiveness and risks of each approach.

Key Points

Cabergoline is a primary medication: It works by lowering prolactin levels and is most effective when taken soon after giving birth to prevent lactation.
Bromocriptine is rarely used for this purpose: Due to significant risks of serious side effects, such as cardiovascular events, its use for routine lactation suppression is restricted.
Gradual weaning is the safest method: Slowly reducing feeding or pumping sessions is the recommended non-medication approach, minimizing discomfort and complications.
Supportive care manages symptoms: Wearing a supportive bra, using cold compresses, and taking pain relievers can alleviate the discomfort of engorgement during weaning.
Hormonal shifts can impact mood: Changes in hormone levels during weaning can affect mood, and seeking support is important for emotional well-being.
Consult a healthcare provider: Medical supervision is critical for anyone considering medication or experiencing complications during the weaning process.

For many new parents, the decision to stop breastfeeding is a significant one, whether it is for personal or medical reasons. While lactation often stops naturally over time, some individuals may seek a quicker solution. Medical intervention for suppressing lactation has evolved, with some older methods now deemed unsafe for routine use. This article explores the pharmacological options available today, weighing them against safer, non-medication alternatives.

Prescription Medications for Lactation Suppression

Prescription medications designed to stop breast milk production work by influencing the body's hormones, specifically prolactin, which is responsible for milk synthesis. These medications are generally reserved for specific medical circumstances, like stillbirth or HIV infection, rather than for routine use. Consultation with a healthcare provider is essential before considering any pharmaceutical approach.

Cabergoline (Dostinex)

Cabergoline is a dopamine agonist that inhibits prolactin secretion. It is a potent and generally well-tolerated option for suppressing lactation, especially when administered shortly after birth. For women with an established milk supply, however, its effectiveness is often reduced. Side effects are typically mild and may include dizziness, headache, and nausea.

Bromocriptine (Parlodel)

Bromocriptine is another dopamine agonist that was historically used to suppress lactation. However, its use for this purpose is now heavily restricted in many regions, including the European Union and the United States, due to concerns over serious side effects. These potential risks include stroke, seizures, and cardiovascular issues. Due to these dangers, bromocriptine is only used in rare, specific cases where medical necessity outweighs the risks.

Hormonal Contraceptives

Some hormonal birth control pills containing estrogen have been shown to decrease milk production. A short course of a low-dose estrogen and progesterone pill may be prescribed by a physician to help suppress lactation, particularly in cases of overabundant milk supply after the first few weeks postpartum. This method should also be managed under strict medical supervision due to potential side effects like spotting or impacts on fertility.

Non-Medication Methods to Stop Milk Production

For most individuals, the safest and recommended approach for stopping breastfeeding is a gradual, natural process. These methods help reduce discomfort and minimize the risk of complications like mastitis or blocked ducts.

Gradual Weaning

The most gentle method for both parent and baby involves gradually reducing feeding or pumping sessions. By spacing out feeds and decreasing the duration or amount expressed, the body receives a signal to reduce its milk supply over time. This intuitive process can take several days to weeks, but it significantly lowers the risk of pain and engorgement.

Supportive Measures

Simple comfort measures can be used to manage the symptoms of weaning.

Supportive Bra: Wearing a firm, supportive, and comfortable bra 24/7 can help support the breasts and reduce discomfort. Avoid overly tight binding, which can increase the risk of mastitis.
Cold Compresses: Applying cold packs or chilled cabbage leaves to the breasts can help reduce swelling and pain associated with engorgement. Cabbage leaves are an old folk remedy that has some anecdotal evidence for soothing swollen breasts.
Pain Relievers: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage pain and inflammation.

Over-the-Counter Options

Certain non-prescription drugs can also have a secondary effect of reducing milk supply.

Pseudoephedrine (Sudafed): This common decongestant is known to have a drying effect on the body, which can also reduce milk production. Some studies have shown a noticeable decrease in milk supply after taking pseudoephedrine. It should be used with caution and under medical guidance, as side effects like anxiety or insomnia can occur.
Herbal Remedies: Herbs like sage and peppermint have long been used in folklore to decrease milk supply. They are generally considered less potent than medical interventions, but some women report success with peppermint tea or sage preparations. Herbal supplements should be approached with caution and discussed with a healthcare provider, as their effects are not always well-studied.

Cabergoline vs. Natural Methods: A Comparison


Feature	Cabergoline (Prescription)	Natural Weaning (Non-Medication)
Speed of Effect	Rapid, especially when started immediately postpartum.	Gradual, takes days or weeks.
Best for Established Lactation?	Less effective; often requires alternative dosing.	Ideal, as it allows the body to adjust slowly.
Mechanism	Decreases prolactin levels.	Reduces milk production through decreased stimulation.
Side Effects	Headache, dizziness, nausea.	Breast engorgement, discomfort.
Risk of Complications	Low, but requires medical screening.	Low risk of mastitis if done gradually.
Medical Supervision	Required due to potential side effects and contraindications.	Recommended, especially with a lactation consultant.
Cost	Prescription cost, can vary by insurance.	Low cost, uses readily available comfort items.

The Emotional Side of Stopping Breastfeeding

Beyond the physical process, it is important to acknowledge the emotional impact of stopping breastfeeding. Hormone fluctuations can lead to feelings of anxiety, depression, or sadness. Mothers should prepare for these emotional changes, which are a normal part of the hormonal shift. Seeking support from a partner, friends, a lactation consultant, or mental health professional can be invaluable during this transition. It is also important to remember that stopping breastfeeding does not reduce the bond between parent and child.

Conclusion: Choosing the Right Path for You

Determining what medication is used to stop breastfeeding milk and whether it is the right choice is a personal decision that should be made in close consultation with a medical professional. For many, a gradual, non-medication approach is the safest and most comfortable way to stop lactation. Prescription medications like cabergoline are effective for rapidly suppressing lactation, especially shortly after childbirth, but they come with potential side effects and are not suitable for all situations. Other drugs like bromocriptine carry significant risks and are rarely used for this purpose anymore. Combining a gradual approach with supportive care and open communication with a healthcare team ensures a smoother and healthier transition for both parent and child.
