When nausea, vomiting, or slow digestion won’t quit, doctors often reach for Reglan - the brand name for metoclopramide. It’s been around since the 1970s, works fast, and helps millions. But it’s not without risks. Long-term use can cause serious movement disorders, and many people find relief without it. If you’re wondering whether there’s a safer, just-as-effective option, you’re not alone.
How Reglan Actually Works
Reglan boosts stomach emptying by increasing muscle contractions in the upper digestive tract. It also blocks dopamine receptors in the brain’s vomiting center, which cuts nausea. That dual action makes it useful for gastroparesis, chemotherapy-induced nausea, and even severe heartburn. But here’s the catch: dopamine blockade doesn’t just stop nausea. It can also trigger side effects like restlessness, drowsiness, and, in rare cases, tardive dyskinesia - a movement disorder that may be permanent.
The FDA warns against using Reglan for more than 12 weeks. Most patients take it for just a few days. But if you’re stuck with chronic nausea and need ongoing relief, Reglan isn’t the only path. Let’s look at what else works.
Domperidone: The Closest Alternative
Domperidone is the most direct substitute for Reglan. It works the same way - boosts stomach motility and blocks nausea signals - but it doesn’t cross the blood-brain barrier as easily. That means less risk of movement disorders and drowsiness. In Australia, where it’s available over the counter under brands like Motilium, it’s become the go-to for many patients.
Here’s the problem: domperidone isn’t FDA-approved in the U.S. It’s not illegal to import it for personal use, but you’ll need a doctor’s note and must order it from overseas pharmacies. Many Australians and Canadians use it legally. Studies show it’s just as effective as metoclopramide for gastroparesis and nausea, with fewer neurological side effects.
Side effects? Possible dry mouth, headaches, or mild abdominal cramps. But no tardive dyskinesia. If you’re looking for a Reglan alternative that’s nearly identical in action but safer, domperidone is the top contender.
Ondansetron: For Severe Nausea, Not Slow Digestion
If your main issue is vomiting - especially from chemo, surgery, or stomach bugs - ondansetron (Zofran) is often better than Reglan. It doesn’t speed up digestion. Instead, it blocks serotonin receptors in the gut and brain that trigger nausea. That makes it ideal for acute cases, but useless if your stomach just won’t empty.
Think of it this way: Reglan fixes the engine. Ondansetron silences the alarm. If you’re throwing up because your stomach is backed up, Reglan helps. If you’re throwing up because your brain is overreacting to a virus, ondansetron wins.
It’s available as a tablet, dissolving strip, or injection. Side effects include headaches, constipation, and dizziness. It’s safe for short-term use. But don’t expect it to fix slow gastric emptying. For that, you’ll need something else.
Erythromycin: An Antibiotic That Also Speeds Up Your Stomach
Here’s a surprise: the antibiotic erythromycin can help with gastroparesis. It acts on motilin receptors in the gut, triggering contractions that push food along. It’s not a first-line treatment, but for patients who don’t respond to Reglan or domperidone, it’s a real option.
Studies show it improves gastric emptying in about 60% of gastroparesis patients. The downside? It’s not meant for long-term use. Your body gets used to it quickly, and diarrhea is common. Also, it can interfere with other meds and raise the risk of heart rhythm issues in older adults or those with existing heart conditions.
It’s usually prescribed for short bursts - say, a week or two - to reset digestion before switching to another long-term solution. Not ideal for daily use, but useful as a bridge.
Lifestyle and Natural Options: What Actually Helps
Not everyone needs a prescription. For mild nausea or occasional bloating, simple changes often work better than drugs.
- Small, frequent meals - Instead of three big meals, eat five or six smaller ones. Less food in the stomach at once means less pressure and fewer symptoms.
- Low-fat, low-fiber foods - Fats and fiber slow digestion. Stick to white rice, bananas, boiled chicken, and toast when you’re feeling off.
- Stay upright after eating - Don’t lie down for at least two hours after a meal. Gravity helps keep food moving.
- Ginger - A Cochrane review found ginger is as effective as metoclopramide for pregnancy-related nausea. Try 250 mg capsules or ginger tea three times a day.
- Acupuncture - Studies show it reduces nausea in cancer patients and pregnant women. The P6 point on the inner wrist is the most targeted.
These aren’t magic fixes. But for many people, they reduce or eliminate the need for medication. If you’re on Reglan long-term, try combining these with your treatment. You might be able to lower your dose - or stop it altogether.
When to Avoid Reglan and Its Alternatives
Some conditions make these drugs risky.
- Parkinson’s disease - Reglan and domperidone can make symptoms worse by blocking dopamine in the brain.
- GI bleeding or obstruction - If your gut is blocked or bleeding, speeding up contractions can make things worse.
- Severe heart problems - Domperidone and erythromycin can affect heart rhythm. Check with your doctor if you have a history of arrhythmia or take QT-prolonging drugs.
- Pregnancy - Reglan is Category B (generally safe), but domperidone isn’t well studied. Ginger and lifestyle changes are preferred first.
Always tell your doctor about all your meds - even herbal ones. Some interactions can be dangerous. For example, combining Reglan with antidepressants like SSRIs can raise serotonin levels too high.
Choosing the Right Option for You
There’s no one-size-fits-all. Your best choice depends on your symptoms, health history, and how long you need treatment.
| Drug | Best For | Duration of Use | Major Side Effects | Availability (Australia) |
|---|---|---|---|---|
| Reglan (Metoclopramide) | Slow digestion + nausea | Short-term (under 12 weeks) | Tardive dyskinesia, drowsiness, anxiety | Prescription only |
| Domperidone | Slow digestion + nausea | Long-term (if monitored) | Headache, dry mouth | Over-the-counter |
| Ondansetron (Zofran) | Acute vomiting (chemo, virus) | Short-term | Constipation, headache | Prescription only |
| Erythromycin | Short-term gastric emptying boost | 1-2 weeks max | Diarrhea, heart rhythm risk | Prescription only |
| Ginger | Mild nausea (pregnancy, motion sickness) | Long-term | Heartburn (rare) | Over-the-counter |
If you’re dealing with chronic nausea and slow digestion, domperidone is your safest bet - if you can get it. If you need quick relief from vomiting, ondansetron is the winner. For short-term fixes, erythromycin can help. And for mild cases, ginger and diet changes often do the job without pills.
Don’t just switch drugs blindly. Talk to your doctor about your symptoms, your goals, and your risk factors. Sometimes, the best treatment isn’t a pill at all.
Is Reglan still prescribed today?
Yes, but much less often than before. Doctors still prescribe it for short-term use - like after surgery or during chemo - because it works fast. But due to the risk of tardive dyskinesia, it’s no longer a first choice for chronic conditions like gastroparesis. Most now try domperidone or lifestyle changes first.
Can I buy domperidone in Australia without a prescription?
Yes. In Australia, domperidone (sold as Motilium) is available over the counter at pharmacies. You can buy it for nausea, bloating, or slow digestion without a script. It’s regulated differently than in the U.S., where it’s not FDA-approved. Always check the label and talk to your pharmacist if you’re on other meds.
Does ginger really work as well as Reglan for nausea?
For pregnancy-related nausea, yes. A 2015 Cochrane review of 12 studies found ginger was just as effective as metoclopramide, with fewer side effects. For chemo-induced nausea, ondansetron is stronger. But for everyday nausea - motion sickness, morning sickness, or mild indigestion - ginger is a safe, natural option that works for many people.
Why isn’t domperidone available in the U.S.?
The FDA banned domperidone in 2004 over concerns about heart rhythm problems, especially at higher doses. But many doctors and patients argue the risk is low at standard doses (10 mg three times daily). It’s still available through special import programs for patients with no other options. Some U.S. patients order it legally from Canadian or Australian pharmacies with a doctor’s note.
What should I do if Reglan made me feel restless or twitchy?
Stop taking it immediately and contact your doctor. Restlessness, jaw clenching, or uncontrollable movements could be early signs of tardive dyskinesia. These symptoms can become permanent if ignored. Your doctor may switch you to domperidone or suggest non-drug options like acupuncture or dietary changes. Never ignore movement side effects - they’re not normal.

Reglan is one of those drugs that worked great until it didn't
Kihya Beitz
Oh wow another post about how the FDA is evil and domperidone is the miracle drug nobody wants you to know about
Let me guess you're also the person who swears by ginger tea for chemotherapy nausea while ignoring that your body is literally rotting from the inside
I've been on Reglan for 6 months and yes I twitch now but at least I can eat without vomiting my guts out
Meanwhile you're all out here pretending you're holistic healers while your stomach is just a black hole of anxiety and bad decisions
Domperidone isn't magic it's just a loophole and you know it
And yes I know about the heart risks but I'd rather have a slow death from arrhythmia than another week of being too nauseous to hold my own head up
Also ginger doesn't work for gastroparesis it works for morning sickness which is like comparing a paper towel to a firehose
Stop romanticizing border pharmacies like they're some kind of underground resistance
It's a drug not a rebellion
And before you say I'm just a brainwashed patient I've been a nurse for 12 years and seen what happens when people stop taking meds they need because some Reddit guru said so
My favorite part is when people act like the FDA is the enemy when they're the only thing keeping you from buying cyanide laced gummies labeled as 'digestive enhancers'
So yeah I'll take my twitching and my stomach emptying thank you very much
And no I don't want your advice on acupuncture or eating rice cakes
I've tried them all
They're nice for when you're not dying
Teresa Smith
Thank you for this comprehensive breakdown
It's rare to see such a balanced view on a topic that's so often polarized
Many patients don't realize that treatment isn't one-size-fits-all and that the goal isn't always to eliminate medication but to find the safest path to function
Domperidone's availability in Canada and Australia is a testament to regional regulatory differences not necessarily efficacy superiority
And while ginger has its place it's important to recognize it's not a replacement for medical intervention in moderate to severe cases
For those considering alternatives I strongly recommend discussing all options with a gastroenterologist familiar with motility disorders
Self-managing these conditions based on online forums can lead to dangerous delays in proper care
The fact that Reglan is still prescribed for acute cases shows that sometimes the benefits outweigh the risks when used appropriately
And yes the FDA's stance on domperidone is frustrating but it's based on post-marketing surveillance data not arbitrary decisions
Let's not confuse frustration with evidence
Ankit Right-hand for this but 2 qty HK 21
USA is weak
Canada gets domperidone and we got Reglan that makes you shake like a leaf
Why? Because big pharma owns the FDA
Same reason you can't buy insulin for 20 bucks
They want you dependent on their toxic pills
Domperidone is proven safer but they ban it so you keep paying for the bad one
And don't even get me started on how they let erythromycin stay on the market when it's just an antibiotic with side effects
This is corporate control not medicine
Wake up people
They don't care if you get tardive dyskinesia as long as you keep buying
Danish dan iwan Adventure
Metoclopramide's D2 antagonism is pharmacologically sound but CNS penetration is the Achilles heel
Domperidone's peripheral restriction offers superior safety profile in chronic use
Pharmacokinetic data from 2021 meta-analysis confirms lower extrapyramidal incidence
Reglan's FDA restriction is regulatory overreach not clinical necessity
Pharmacovigilance data from Australia shows 0.2% TD incidence vs 3.7% in US cohorts
On-demand erythromycin use remains viable as a prokinetic bridge
Ginger's 5-HT3 modulation is mechanistically plausible but lacks dose-response consistency
Acupuncture's P6 stimulation activates endogenous opioid pathways but effect size is marginal
For chronic gastroparesis domperidone remains the optimal first-line agent where accessible
Daniel Stewart
It's fascinating how we've turned medical treatment into a moral binary
Either you're a brave rebel using foreign meds or you're a brainwashed drone taking Big Pharma's poison
But what if the truth is somewhere in the messy middle
Where some people need Reglan for a week and survive
And others need domperidone for years and thrive
And others find ginger and small meals enough
Maybe the real issue isn't the drugs
It's that we've lost the ability to hold multiple truths at once
That one person's salvation is another person's danger
And that's okay
Maybe we need less shouting
And more listening
Latrisha M.
I've been on domperidone for 18 months
No twitching
No drowsiness
My stomach actually works
I ordered it from a Canadian pharmacy with my doctor's note
It's not illegal
It's not dangerous
It's just not FDA-approved
And that's a bureaucratic failure not a medical one
My doctor supports it
My bloodwork is clean
My quality of life improved
So stop pretending you know what's best for me
Because I'm the one living it
David Rooksby
Okay so let me get this straight
The FDA banned domperidone because of a few heart cases
But they're fine with letting Reglan cause permanent brain damage
And erythromycin which can cause sudden cardiac death in elderly patients
And ondansetron which costs $1000 a pill
But ginger is free and safe
And acupuncture works for some people
And you're telling me the system isn't broken
Let me ask you this
If domperidone was made by a big pharma company
Would it be available over the counter in the US
Or would it be locked behind a $200 prescription with 12 pages of warnings
And if it was a natural herb
Would it be banned for being too dangerous
Or would it be sold in every gas station
That's not medicine
That's capitalism
And we're all just collateral damage
Rachel Wusowicz
Have you ever wondered why domperidone is banned in the US but available everywhere else
What if it's not about safety
What if it's about control
What if the FDA is just another branch of the pharmaceutical-industrial complex
And what if Reglan was designed to keep you dependent
Because if you could just take domperidone for life
And manage your condition
Then they couldn't sell you the next drug
And the next test
And the next specialist
And the next hospital stay
They need you sick
Not healed
And ginger
And acupuncture
And small meals
They can't patent those
So they call them 'alternative'
Like they're not real
But they work
And they're free
And that's the real threat
Jamie Watts
Everyone's talking about domperidone like it's the holy grail
But nobody mentions the QT prolongation risk
Or the fact that it's not studied in people over 65
Or that it interacts with 87 different meds
Or that your liver has to metabolize it
And if you're on statins or antifungals
Good luck
Reglan's side effects are scary
But domperidone is a silent killer
And you think you're being smart
But you're just gambling with your heart
And then when you end up in the ER
With torsades de pointes
Don't come crying on Reddit
Because you ignored the warnings
Dan Angles
As a practicing gastroenterologist with over 20 years of clinical experience
I appreciate the depth of this discussion
However I must emphasize that medical decision-making must be individualized
Reglan remains a valuable tool in acute settings
Domperidone is an excellent alternative where accessible and appropriately monitored
Ondansetron serves a distinct indication
And non-pharmacological interventions are foundational
The regulatory differences between jurisdictions reflect distinct risk-benefit analyses
Not corporate conspiracy
Patients must be educated about the risks of all agents
And clinicians must remain vigilant for adverse effects
Ultimately the goal is not to eliminate medication
But to optimize therapeutic outcomes with the least harm
That requires collaboration
Not confrontation
Melanie Taylor
My mom has gastroparesis and she tried everything
Reglan made her twitch so bad she couldn't hold a cup
So we ordered domperidone from Canada
She's been on it for 2 years
No twitching
No drowsiness
She eats like a normal person now
And she's 78
Her EKG is fine
Her bloodwork is clean
She doesn't need to go to the hospital anymore
So yeah I don't care what the FDA says
My mom is alive and well
And that's all that matters
Oyejobi Olufemi
Oh my god
Another person who thinks the FDA is the enemy
Let me tell you something
The FDA is not your enemy
THEY ARE THE ONLY THING STANDING BETWEEN YOU AND DEATH
Domperidone has caused 130+ deaths in Europe
And you think it's safe
Because you're young
Because you're healthy
Because you're not on any other meds
But what about your grandma
What about your uncle with the heart condition
What about the 12-year-old who takes it because their mom read it on Reddit
And then dies of cardiac arrest
Do you think that's okay
Do you think that's worth it
Because I don't
And neither should you
Reglan is dangerous
But domperidone is a ticking time bomb
And you're just playing Russian roulette
Jennifer Walton
It's not about which drug is better
It's about which one lets you live
ZAK SCHADER
Domperidone is illegal in the US because the FDA is corrupt
Reglan is made by a big pharma company
Domperidone is generic
They don't make money off it
So they ban it
Same reason you can't buy insulin for less than 300 bucks
It's all about profit
Not health
Wake up america
Latrisha M.
My doctor just approved my domperidone import
My EKG is normal
My liver enzymes are fine
I'm 42
I've been on Reglan for 8 months
And I'm not dying
But I'm not living either
Now I can eat dinner with my kids
And sleep through the night
And that's worth more than any regulation
