The moment you start worrying about your milk supply, everything can feel a bit more overwhelming. We know that feeling of watching the ounces in a bottle or wondering if your baby is truly satisfied after a long nursing session. It is a common concern that brings many parents to a point where they wonder if a prescription might be the answer. If you have been searching for what medication can you take to increase milk supply, you are likely looking for clarity, safety, and a path forward that feels right for you and your baby.
At Milky Mama, we believe that education is the strongest tool in your breastfeeding journey. This post will explore the different medications available, how they work in the body, and the important safety considerations you should discuss with your healthcare provider. We will also look at the steps to take before reaching for a prescription and how to support your body naturally. While medication is an option for some, it is just one part of a much larger picture of lactation support.
Understanding your options can help you feel more in control of your feeding goals. We are here to walk you through the clinical details of galactagogues (substances that increase milk) so you can make an informed decision. Every breastfeeding journey is unique, and finding the right support often requires a blend of technique, patience, and the right tools.
Before diving into specific medications, it is helpful to understand the term "galactagogue." A galactagogue is simply any substance that is believed to assist in the initiation, maintenance, or increase of milk production. These can be herbal, like those found in some of our lactation supplements, or they can be pharmaceutical.
In the medical world, galactagogues usually work by influencing the hormones that tell your body to make milk. The most important hormone in this process is prolactin. Prolactin is often called the "milk-making hormone" because it stimulates the milk-producing cells in the breasts (the alveoli) to do their job.
Your body naturally manages prolactin levels using a chemical called dopamine. In a typical cycle, dopamine acts as a "brake," keeping prolactin levels in check. Most medications used to increase milk supply work by blocking dopamine. When the "brake" is removed, prolactin levels rise, which can lead to an increase in milk volume for some people.
Before considering any medication, it is vital to determine if your supply is actually low or if you are experiencing what we call "perceived low supply." It is very common to feel like you aren't making enough, especially during growth spurts or when your breasts start to feel softer a few weeks postpartum.
A true low milk supply means your baby is not receiving enough milk to grow and thrive. This is relatively uncommon, affecting a small percentage of breastfeeding parents. Many times, the issue isn't the body's ability to make milk, but rather how effectively the milk is being removed.

In the United States, Metoclopramide, commonly known by the brand name Reglan, is one of the most frequently prescribed medications for increasing milk supply. While its primary use is for gastrointestinal issues like acid reflux or slow stomach emptying, its side effect of increasing prolactin makes it a common "off-label" choice for lactation.
Reglan works by blocking dopamine receptors. Since dopamine inhibits prolactin, blocking it allows prolactin levels to climb. This spike in prolactin may signal the breasts to increase production. For some, this change happens within 24 to 48 hours.
While Reglan can be effective, it is a medication that requires careful monitoring. The most significant concern is its impact on mental health. Because it crosses the blood-brain barrier, it can cause or worsen symptoms of depression and anxiety.
We always recommend that anyone with a history of depression or postpartum depression avoid this medication. Even for those without a history, it is crucial to watch for signs of mood changes, irritability, or feelings of hopelessness. Other side effects can include:
If a doctor prescribes Reglan, they will usually suggest a short course, often around 10mg three times a day for one to two weeks. It is important to taper off this medication slowly rather than stopping abruptly, as a sudden drop can cause a dip in milk supply or withdrawal symptoms.
Domperidone is perhaps the most well-known lactation medication globally. It is widely used in Canada, Europe, and Australia. However, its status in the United States is complicated. The FDA has not approved Domperidone for any use in the U.S., and they have issued warnings against its use for lactation.
In 2004, the FDA issued a warning because of potential cardiac risks associated with high-dose, intravenous use of Domperidone. While breastfeeding parents take the medication orally and at much lower doses, the FDA remains cautious. Despite this, some parents in the U.S. still seek it out through international pharmacies or specialized compounding pharmacies under strict medical supervision.
Many lactation experts outside the U.S. prefer Domperidone over Reglan because it does not cross the blood-brain barrier as easily. This means it is much less likely to cause the severe depression and anxiety associated with Reglan. It still works by blocking dopamine to increase prolactin, but its effects are more localized to the digestive system and the pituitary gland.
The primary risk associated with Domperidone is its effect on the heart's rhythm, specifically the "QT interval." For most healthy, young individuals, the risk is very low. However, it should never be taken by anyone with a history of heart conditions or by those taking other medications that affect heart rhythm.
Common side effects of Domperidone include:
In some parts of the world, other medications like Sulpiride are used. Sulpiride is an antipsychotic medication that, like the others, has the side effect of raising prolactin levels. It is not commonly used in the U.S. for lactation due to the availability of other options and a lack of extensive research on its use specifically for breastfeeding.
Regardless of the medication being considered, it is essential to remember that these drugs do not work for everyone. If a person already has high or normal prolactin levels, taking a dopamine blocker may not result in any additional milk. Medication is most effective when a hormonal deficiency is the specific cause of the low supply.
Key Takeaway: Medication for milk supply should never be the first line of defense. It is most effective when used as a short-term tool alongside professional lactation support to address the root cause of the issue.
Before you and your doctor decide on a prescription, there are several foundational steps to ensure your body is being given every chance to produce milk naturally. Lactation is a "supply and demand" system, and sometimes the demand just needs to be communicated more clearly to your body.
A baby who isn't latched well cannot remove milk efficiently. If milk stays in the breast, your body receives a signal to slow down production. Working with an IBCLC (International Board Certified Lactation Consultant) to improve the latch can often solve supply issues without any medication.
If you need personalized guidance, Milky Mama's breastfeeding help and lactation consultations can provide support with latch, pumping, and low milk supply concerns.
The more often you empty your breasts, the more milk you will make. This might mean adding a pumping session after nursing or trying "power pumping." Power pumping mimics a baby's cluster feeding by pumping for short bursts over the course of an hour (for example: pump 20 minutes, rest 10, pump 10, rest 10, pump 10).

Holding your baby skin-to-skin (baby in just a diaper against your bare chest) releases oxytocin. Oxytocin is the hormone responsible for the "let-down reflex," which pushes the milk out of the ducts. Spending a "baby moon" day in bed just cuddling and nursing can do wonders for supply.
Certain medical conditions can hinder milk production. These include:
If you have an underlying condition, treating that condition is often the key to unlocking your milk supply.
Many parents prefer to try herbal support before moving to prescription drugs. There are several plants and foods known for their galactagogue properties. These ingredients are the foundation of what we do. We focus on using high-quality, evidence-based ingredients to support your body's natural processes.
Our herbal supplements, such as Pumping Queen™ or Milk Goddess™, are designed to provide these supportive nutrients in a convenient way. These can be a great middle ground for parents who need a boost but aren't ready for or don't require prescription medication.
If you feel that you have tried all the mechanical and herbal adjustments and your supply is still not meeting your baby's needs, it is time for a detailed conversation with your healthcare provider.
When you go to your appointment, be prepared to discuss:
Your doctor should work with you to weigh the benefits of increased milk production against the potential side effects of the medication. It is also helpful to have a plan for how long you will take the medication and how you will eventually stop taking it.
It is important to be realistic about what medication can do. For some, it may significantly increase their supply within a few days. For others, the increase might be modest, or they might not see a change at all.
Medication is rarely a "set it and forget it" solution. You must continue to remove milk frequently through nursing or pumping for the medication to work. Think of the medication as a "volume knob" that only works if the "music" (milk removal) is already playing.
If you find that your supply increases on medication but drops once you stop, you may need to work with a lactation consultant to figure out a very gradual tapering schedule. This allows your body time to adjust and helps you maintain the gains you have made.
If you are currently struggling with supply and considering your options, here is a simple action plan:
We cannot emphasize enough how much stress and exhaustion can impact your milk supply. When your body is in "fight or flight" mode due to lack of sleep or high anxiety, it may prioritize other functions over milk production.
While it is easier said than done with a newborn, try to find small windows for rest. Even a 20-minute nap or a quiet shower can help lower your cortisol levels. High cortisol can inhibit the let-down reflex, making it harder for milk to flow. Sometimes, the "medication" a parent needs most is a few hours of uninterrupted sleep while a partner or friend watches the baby.
Deciding what medication can you take to increase milk supply is a personal choice that should be made with professional medical guidance. Whether you choose a prescription like Reglan or Domperidone, or opt for natural support through herbs and lifestyle changes, know that you are doing an amazing job. Breastfeeding is a journey with many peaks and valleys, and seeking help is a sign of your dedication to your baby’s well-being.

In the United States, medications like Metoclopramide (Reglan) require a prescription from a licensed healthcare provider. While herbal supplements are available over the counter, pharmaceutical galactagogues must be managed by a doctor to ensure safety and proper dosing.
Many parents notice an increase in milk supply within 24 to 72 hours of starting a medication like Reglan. However, for some, it may take up to a week to see the full effect, and the results can vary significantly from person to person.
It is possible for milk supply to decrease once the medication is discontinued, especially if it is stopped abruptly. To help maintain your supply, most lactation consultants recommend tapering the dose slowly while continuing to nurse or pump frequently.
Both Metoclopramide and Domperidone pass into breast milk in very small amounts. While they are generally considered compatible with breastfeeding, you should always monitor your baby for any changes in behavior, such as unusual sleepiness or digestive upset, and report them to your pediatrician.
