What Medications Help Induce Lactation and Do They Have Side Effects?
Are there medications that can help induce lactation and are they safe?
This is one of the most common questions I hear from parents exploring induced lactation and relactation.
Let’s walk through what medications are sometimes used, what the research actually says, and how side effects fit in. As always, this is information, not personal medical advice. Medication decisions belong to you and your medical team.
First Things First: What Are Galactagogues?
Galactagogues are substances (medications or herbs) used to help boost milk production. They’re sometimes considered when a parent has done a lot of the “basics” and is still struggling with low supply or wants to support induced lactation as a non-gestational parent.
Here’s the important piece that often gets skipped in TikTok videos and Facebook threads:
No galactagogue (medication or herb) will work without milk extraction.
That means:
Regular, effective milk removal with a pump, hand expression, baby at the breast, or some combination of those
A realistic, sustainable schedule that your body and life can actually handle
Attention to latch, positioning, and any medical reasons supply might be low
Medications and herbs can sometimes give the body an extra nudge. But they’re the support act, not the star of the show. The star is still frequent, effective milk removal.
Why Might Someone Consider Medication?
In induced lactation and relactation, we’re often asking a lot from a body that hasn’t had a recent pregnancy or that has already weaned. Sometimes, even with strong stimulation and good technique, supply stays lower than hoped. That can feel frustrating, especially when you’ve invested time, energy, and a lot of heart.
In some cases, after we’ve:
Optimized the pumping or nursing routine
Checked in on medical conditions (like thyroid concerns, iron levels, hormonal conditions)
Worked on latch and positioning (if baby is already home)
…then we may talk about whether a galactagogue might be appropriate. This is always done with:
Careful explanation of benefits and risks
Collaboration with the parent’s physician
Realistic expectations (boost, not magic)
Let’s look at some of the common medications you might hear about.
Domperidone: The “Big Name” In Galactagogues
Domperidone is one of the best studied medications used to increase milk supply. It works by blocking dopamine receptors, which allows prolactin (the milk making hormone) to rise. Some studies have shown modest increases in milk volume in certain parents, especially when combined with good milk removal practices.
However, domperidone comes with important caveats:
It is not approved by the FDA in the United States specifically for increasing milk production.
There are known cardiac risks, particularly at higher doses or in people with certain underlying heart conditions or when combined with other medications that affect the heart’s electrical system.
Different countries regulate it differently, and access can vary.
Personally:
I support the use of domperidone only with direct medical supervision by a physician who knows your health history and can monitor you appropriately.
I do not support sourcing domperidone online or through questionable channels. There are simply too many unknowns (dose, purity, interactions) and too much potential risk.
If domperidone is being considered, I encourage parents to:
Speak with their physician about their cardiac history and current medications
Discuss appropriate dosing, duration, and monitoring plans
Check whether the potential benefits outweigh the risks in their specific situation
Domperidone can be helpful in the right circumstances, but it should never be a DIY project.
Metoclopramide: Another Commonly Mentioned Option
Metoclopramide (often known by the brand name Reglan) is another medication that’s been used to increase milk supply. Like domperidone, it works by affecting dopamine and can raise prolactin levels.
It has some key considerations:
Some parents see a modest increase in supply.
It can cross the blood brain barrier more easily than domperidone, which means it has a higher risk of central nervous system side effects.
Side effects can include fatigue, restlessness, gastrointestinal symptoms, and mood changes. Some parents experience new or worsened depression or anxiety when taking it.
Because of this, if metoclopramide is used, it’s often:
For a limited time
At a carefully chosen dose
With close monitoring, especially in parents with a history of mood disorders
Again, this is a decision for you and your physician. My role as an IBCLC is to:
Explain what the medication is and how it works in the context of lactation
Flag mental health as a crucial part of the conversation
Make sure we have a clear plan for what to do if side effects show up
If your mental health starts to suffer because of a medication, the plan needs to change. Protecting your wellbeing is just as important as protecting your supply.
Other Medications You Might Hear About
You may come across lists of other medications online. Things like sulpiride, chlorpromazine, oxytocin nasal sprays, or even more experimental options. In general:
The evidence for many of these is limited, inconsistent, or based on small studies.
Some carry significant side effect profiles that make them less appealing for routine use.
In my practice, I don’t maintain a “never, ever” blacklist on behalf of your physician. Instead, I:
Acknowledge that some medications exist in the literature but are rarely used in everyday practice
Encourage you to bring any medication ideas to your doctor, who can weigh up to date evidence, your full health picture, and current guidelines
Focus on building a plan where any medication, if used, is just one carefully considered tool, not the centerpiece of the journey
The bottom line: if you see a long list of “magic” medications in a forum, take a breath, screenshot it, and bring it to your medical team. Don’t experiment alone.
Herbal Galactagogues: “Natural” Doesn’t Mean Risk-Free
Herbal galactagogues (things like fenugreek, blessed thistle, goat’s rue, milk thistle, and more) are everywhere. They’re in teas, capsules, tinctures, and powders. The marketing can sound gentle and reassuring: “just a little herbal support.”
Here’s how I approach herbs in induced lactation and relactation:
We talk about them openly. I don’t ignore herbs or pretend they don’t exist.
I emphasize that “natural” does not automatically mean safe for every person or in every combination.
I strongly prefer that herbs be used with physician awareness, especially if you’re on other medications or have conditions like asthma, blood sugar concerns, thyroid conditions, or clotting disorders.
Why the caution?
The evidence for many herbs is limited, with small or lower quality studies. Some may help; some may not; for others, we simply don’t know enough.
Herbs can interact with prescription medications or exacerbate certain conditions.
Supplements are not always regulated with the same rigor as prescription medications, so purity and dosage can vary.
And, just like with pharmaceuticals:
No herb will increase supply in a meaningful way without regular, effective milk extraction.
If you choose to use herbal galactagogues, I encourage you to:
Share the exact products and doses with your physician
Keep an eye on how you feel physically and emotionally
Be honest about what you’re taking. Your healthcare team can only keep you safe if they know what’s in the mix
So…Do These Medications And Herbs Actually Work?
The honest answer is: sometimes, for some people, in the right context.
Research suggests that:
Certain galactagogue medications, like domperidone, can increase milk volume modestly when used in carefully selected parents, especially when paired with robust milk removal routines.
Other medications, like metoclopramide, may offer some benefit but come with more central nervous system side effects and require cautious use.
Herbal galactagogues might help some parents, but the evidence is highly variable, and side effects and interactions are often under discussed.
What they don’t do:
They don’t replace frequent, effective milk extraction.
They don’t guarantee an exclusive milk supply.
They don’t erase the emotional and physical realities of induced lactation, trauma history, or life stress.
In other words, medications and herbs can sometimes add “boosters” to a well built plan, but they can’t be the plan.
How I Work With Parents Who Are Considering Medication
Every parent, every body, and every adoption or relactation story is different. That means there’s no one “right” answer about using medications or herbs. Here’s how I typically approach it:
We start with your goals.
Are you hoping for a full supply, partial supply, or primarily a comforting, bonding nursing relationship? Different goals can shape whether medication is worth considering.We build foundations first.
We look at your pumping or nursing schedule, your equipment, your technique, and any at breast supplementation we might use (like an SNS). We shore up the parts of the plan that don’t require prescriptions.We review your health story.
We talk about your medical history, mental health, current medications, and any risk factors that might influence medication choices.We bring your physician into the conversation.
I don’t prescribe medications or herbs. Instead, I provide information, share the lactation specific context, and encourage you to have an open, detailed conversation with your doctor. Together, we figure out what might be reasonable.We emphasize informed consent and monitoring.
If a medication or herb is started, we talk ahead of time about how you’ll monitor for side effects, how long you’ll trial it, and under what circumstances you’d stop or adjust.We keep attachment and mental health at the center.
If a medication or herb is increasing your anxiety, worsening depression, or adding more stress than benefit, that’s important data. Sometimes the most loving choice is to step back from a medication so you can be more present and grounded with your baby.
When Medications Might Not Be The Right Fit
There are absolutely times when we decide that medication is not a good option, or not worth the tradeoffs.
This might be the case if:
You have a significant cardiac history or are on medications that make domperidone particularly risky.
You have a history of depression or anxiety, and the potential mood side effects of certain drugs feel too risky for where you are right now.
Your life is already at capacity, and adding another thing to track, swallow, and worry about would create more stress than relief.
After a trial period, we see little to no benefit in milk volume or nursing experience.
In those situations, choosing not to pursue, or not to continue, a medication or herb is not a failure. It’s a thoughtful, protective decision.
Remember: breastfeeding or chestfeeding is one way to nurture connection, not the only way. The love you pour into your baby is not measured in milliliters.
If you’ve stuck with me this far and are considering medications or herbs to help induce Lactation:
Remember:
You’re allowed to ask these questions. Wanting to do “everything you can” for your baby is a normal, loving instinct.
Medications and herbs can sometimes help, but they are tools, not magic. They work best on top of a strong foundation of milk extraction, realistic expectations, and good support.
Safety matters. Domperidone, metoclopramide, and herbal galactagogues all have potential side effects and interactions. They should be used, if at all, with physician oversight (not sourced quietly online or taken in secret).
Your mental health and your attachment with your baby matter more than any protocol. We can adjust the plan. We can redefine success. You don’t have to push through side effects to prove anything.
If you’re curious about what medications and herbs might look like within a whole person induced lactation plan, I’d love to walk alongside you. In my induced lactation journeys, we combine evidence based education, individualized planning, and ongoing support so that any decisions about galactagogues are collaborative and centered on you and your baby.
If you’d like to explore what this might look like for your unique body and story, you’re always welcome to reach out and schedule a free 15-minute meet & greet so we can talk it through together.
