Domperidone Veterinary: Uses, Safety, and Alternatives for Pets

When your dog or cat is vomiting nonstop or seems nauseous, you might hear your vet mention domperidone, a dopamine receptor blocker used off-label in veterinary medicine to treat nausea and improve gut motility. Also known as Motilium, it’s not FDA-approved for pets, but it’s widely used by veterinarians because it works without crossing the blood-brain barrier—unlike metoclopramide—which means fewer neurological side effects in animals. This makes it a go-to for dogs with vomiting from gastritis, delayed gastric emptying, or even some forms of canine parvovirus recovery.

Domperidone veterinary use is mostly for dogs, a common species where the drug is prescribed for gastrointestinal motility disorders and sometimes for cats, though dosing is trickier and less studied. It’s not used in birds or rabbits due to different digestive systems. The typical dose for dogs is 0.2–0.5 mg per pound, given 2–3 times daily, but it’s always based on weight, condition, and vet guidance. Unlike human use, there’s no standard commercial pet formulation—most vets compound it from human tablets or use liquid versions from specialty pharmacies. You’ll need a prescription, and you should never give it without vet approval, especially if your pet has heart issues, liver disease, or is on other meds like ketoconazole, which can cause dangerous interactions.

What you won’t find in most vet offices is a long-term domperidone plan. It’s usually a short-term fix—think 3 to 7 days—while the real cause is being diagnosed. If your pet keeps vomiting after a week, the issue isn’t just motility; it’s likely something deeper: pancreatitis, kidney failure, or even a blockage. That’s why the posts below cover not just domperidone, but also alternative antiemetics like metoclopramide, ondansetron, and even natural options like ginger or acupuncture that vets recommend when drugs aren’t enough or too risky. You’ll also find real case studies on how vets handle vomiting in senior dogs, how to spot domperidone side effects like diarrhea or lethargy, and why some pet owners switch to probiotics or special diets after the meds are done.

Whether you’re a pet owner trying to understand your vet’s prescription or someone researching options after a bad reaction, this collection gives you the straight facts—not marketing, not guesswork. You’ll see what actually works in real animals, what doesn’t, and how to avoid common mistakes. No fluff. Just what you need to keep your pet safe and comfortable.
