We have all been there—staring at the few drops in the bottom of a collection bottle after a twenty-minute pumping session, feeling a heavy sense of worry. If you have ever found yourself questioning whether your body is doing "enough" for your baby, please know that you are not alone. The pressure to maintain a robust milk supply can be overwhelming, and it is completely natural to look for solutions that might give your body a boost. When the cookies and the extra water don’t seem to be doing the trick, many parents begin to ask a very specific question: are there medications to increase milk supply?
The short answer is yes, there are pharmaceutical options, but they are often considered a last resort and come with a complex set of pros, cons, and safety considerations. At Milky Mama, we believe that every drop counts, and your well-being matters just as much as your milk volume. We want to empower you with the knowledge to make the best decision for your unique journey. In this post, we will take a deep dive into the world of galactagogues—the clinical term for substances that increase milk supply. We will explore the most common medications prescribed off-label for lactation, how they work within the body, the potential side effects you should know about, and why a holistic approach involving both support and nutrition is often the most effective path forward.
By the end of this article, you will have a clear understanding of the medical options available, the importance of professional guidance, and how to balance these choices with nourishing, herbal alternatives that support your body’s natural ability to provide for your little one.
Before we dive into the specifics of medications, it is vital to remember a fundamental truth about our bodies: breasts were literally created to feed human babies. For the vast majority of us, the process is governed by a simple biological law—the law of supply and demand.
In the early days after birth, your milk supply is largely driven by hormones like prolactin and oxytocin. Prolactin is responsible for making the milk, while oxytocin helps with the "let-down" reflex, allowing the milk to flow. However, as you move past the first few weeks, your supply transitions from being purely hormonal to being "autocrine" or milk-removal driven. This means that the more milk you remove from the breast, the more milk your body is signaled to produce.
If the breasts are not being emptied frequently or effectively, a protein called the Feedback Inhibitor of Lactation (FIL) builds up. This protein tells your body to slow down production. This is why we often say that no medication or supplement can replace the physical removal of milk. Whether you are using an electric pump, hand expressing, or nursing your baby, emptying the breast is the most critical step in maintaining supply.
The word "galactagogue" comes from the Greek words "galakta" (milk) and "agogue" (to lead or bring forth). These are substances—ranging from pharmaceutical drugs to herbs and foods—that are believed to assist in the initiation, maintenance, or increase of milk production.
In a clinical setting, healthcare providers usually only consider medications to increase milk supply after a full assessment has been conducted. This often includes:
When these adjustments have been made and supply is still not meeting the baby's needs, a provider might discuss pharmaceutical galactagogues.
There are two primary medications that are most frequently discussed in the lactation world: Domperidone and Metoclopramide. It is important to note that neither of these drugs was originally created for lactation; they are used "off-label" for this purpose.
Domperidone is perhaps the most widely recognized medication for milk supply globally, though its availability and legal status for lactation vary significantly by country.
How it works: Domperidone is an anti-nausea medication that works by blocking dopamine receptors. Because dopamine normally inhibits the release of prolactin, blocking those receptors leads to a rise in prolactin levels. Higher prolactin levels can signal the mammary glands to produce more milk.
The Evidence: Research, particularly involving mothers of premature infants, has shown that domperidone can increase expressed milk volume by a significant margin for some people. Some studies suggest an increase of 86mL to 245mL per day. However, it doesn't work for everyone. Studies show that about one-third of mothers may not see a significant response.
Safety and Risks: While domperidone passes into breast milk in very negligible amounts, the primary concern is for the mother. In rare cases, domperidone can cause cardiac arrhythmias (heart rhythm issues). Because of this, it is usually not recommended for anyone with a history of heart conditions. Common side effects for the parent can include headaches, dry mouth, and abdominal pain.
Metoclopramide is another medication used to treat gastrointestinal issues like reflux and nausea that has the side effect of increasing prolactin.
How it works: Similar to domperidone, it blocks dopamine to stimulate prolactin production.
The Evidence: While it can be effective in increasing supply, it is often considered a second choice to domperidone in countries where both are available because it crosses the blood-brain barrier more easily.
Safety and Risks: This medication has a higher incidence of side effects related to the central nervous system. These can include:
Because of the risk of postpartum depression, many IBCLCs and doctors are very cautious about prescribing Reglan to breastfeeding parents, as the postpartum period is already a time of high emotional vulnerability.
Choosing to use a medication to increase milk supply is a significant decision that should always be made in consultation with a healthcare provider. While the goal is to provide more milk for your baby, the health of the parent is equally important.
One often overlooked aspect of these medications is the "crash" that can happen if they are stopped suddenly. If you use a medication like domperidone for several weeks or months and then stop cold turkey, you may experience withdrawal symptoms such as insomnia, anxiety, and a sharp drop in milk supply. Most experts recommend a very slow tapering process to allow the body to adjust.
As mentioned, the cardiac risks of domperidone and the mental health risks of metoclopramide are the primary reasons these drugs are not used lightly. It is essential to have a full medical screening, including an evaluation of your heart health and mental health history, before starting these treatments.
Medication can sometimes act as a temporary fix without addressing the root cause of low supply. If a baby has a tongue-tie or a poor latch, the medication might increase supply temporarily, but once the medication stops, the supply will likely drop again because the physical demand is still not being met effectively. This is why we highly recommend virtual lactation consultations to identify the "why" behind the supply struggle.
For many families, the risks associated with pharmaceutical medications are a deterrent. This is where herbal galactagogues and specialized nutrition come into play. At Milky Mama, we focus on using time-tested, nourishing ingredients that support the body without the intense side effects of synthetic drugs.
Herbs have been used for centuries to support breastfeeding. Our liquid gold supplements are formulated by an RN, BSN, IBCLC to provide specific types of support.

Hydration is a cornerstone of milk production. However, drinking plain water all day can get boring. We developed our lactation drinks to provide both hydration and lactation-supporting ingredients in a delicious format.
If you can't decide which one to try, our Drink Sampler Packs are a great way to find your favorite flavor.
Breastfeeding is hard work and burns a significant amount of calories. Sometimes, the best way to support your supply is to simply ensure you are eating enough nourishing foods. Our lactation snacks are designed to be both delicious and functional.
Our bestseller, the Emergency Brownies, are famous for a reason. They provide a dense, fudgy dose of ingredients like oats and flax, which are traditionally used to support supply. We also offer a variety of cookies, including Oatmeal Chocolate Chip, Salted Caramel, and even a Fruit Sampler for those who love variety.
While you are considering your options regarding medications or supplements, there are several "at-home" strategies you can implement right now to help your body produce more milk.
The more often you empty the breast, the faster your body will make milk. If you are nursing, try adding an extra feeding or two. If you are pumping, consider adding a short "power pumping" session once a day. Power pumping mimics a baby cluster feeding: pump for 20 minutes, rest for 10, pump for 10, rest for 10, and pump for 10.
Never underestimate the power of a "baby moon." Spending time skin-to-skin with your baby triggers a massive release of oxytocin, which helps your milk flow and can stimulate prolactin production. It also encourages the baby to nurse more frequently.
If you are an exclusive pumper or pump frequently at work, your supply might actually be fine, but your pump might be failing you. Check your valves and membranes for any small tears or loss of elasticity. Replacing these parts regularly is essential for maintaining proper suction and milk removal.
Studies have shown that using your hands to gently massage the breast while pumping can increase the amount of milk you collect and also increase the fat content of that milk. It helps to ensure the breast is truly empty, which signals the body to make more.
Breastfeeding is natural, but it doesn’t always come naturally. If you are struggling with supply, the most important thing you can do is seek help early. You don't have to navigate this alone.
We offer online breastfeeding classes, including our foundational Breastfeeding 101 course. These resources are designed to give you the confidence and tools you need to succeed from the very beginning.
If you are already in the thick of it and feeling overwhelmed, a virtual lactation consultation can be a game-changer. Our certified consultants can look at your specific situation, evaluate your pumping routine, and help you decide if herbal supplements or a conversation with your doctor about medication is the right next step.
We want to take a moment to validate the feelings that come with supply concerns. It is okay to feel frustrated, sad, or even like you are failing—but we want you to know that you are not failing. Your worth as a parent is not measured in ounces. Whether you provide one drop of breast milk or a full freezer stash, you are doing an amazing job.
In many cultures, especially within the Black community, breastfeeding has faced historical barriers and a lack of representation. At Milky Mama, we are committed to changing that narrative. We believe that every family deserves compassionate, culturally competent support. We want you to feel empowered in your body’s ability to nourish your child, while also feeling supported when you need to lean on tools like supplements or medications.
If you do decide that you want to explore the question, "are there medications to increase milk supply?" with your doctor, here are a few tips for that conversation:
Remember, your doctor is there to work with you. If you feel like your concerns are being dismissed, it is always okay to seek a second opinion or talk to a specialist who has more experience in lactation medicine.
The journey of breastfeeding is rarely a straight line. It is filled with peaks and valleys, and questioning your milk supply is a very common part of that path. While there are medications to increase milk supply, they are just one small piece of a much larger puzzle. They come with benefits that must be carefully weighed against their risks and should always be part of a comprehensive plan that includes frequent milk removal and professional support.
Whether you choose to explore pharmaceutical options, prefer the herbal support of our lactation supplements, or find success through power pumping and skin-to-skin contact, please know that we are here for you. Our community is built on the belief that moms deserve support, not judgment.
You are doing the hard work of nourishing a human being, and that is a beautiful, powerful thing. Keep going, take care of yourself, and remember—every drop counts.
1. How long does it take for medications to increase milk supply? For most people who respond to medications like domperidone, an increase in milk volume is typically seen within 7 to 14 days. However, the maximum effect may take up to three or four weeks of consistent use and frequent milk removal.
2. Can I take herbal supplements and prescription medications at the same time? You should always consult with your healthcare provider or a pharmacist before combining herbal supplements with prescription medications. Some herbs can interact with drugs or have similar effects that might become too intense when combined.
3. Is it legal to use domperidone for breastfeeding in the United States? In the United States, the FDA has not approved domperidone for any use, including lactation, due to concerns about cardiac side effects. However, it is legally prescribed and widely used for lactation in many other countries, including Canada, the UK, and Australia. Always discuss the legal and safety status of any medication with your local provider.
4. Will my milk supply drop as soon as I stop taking the medication? If the medication is stopped abruptly, many people do experience a sharp decline in supply. To prevent this, healthcare providers usually recommend a very gradual weaning process—slowly reducing the number of doses per day over several weeks while maintaining a frequent pumping or nursing schedule.
