Metoclopramide for Cockatiels: Uses, Crop Motility & Side Effects

This information is for educational purposes only. Never give your pet any medication without your veterinarian's guidance. Dosing, frequency, and safety depend on your pet's specific health profile.

Metoclopramide is a prescription medication your vet may use to help move food through the upper digestive tract and reduce nausea. In veterinary medicine, it is best known as a prokinetic, meaning it can stimulate movement in the stomach and upper small intestine. In birds, it may also be used as part of supportive care when crop emptying is delayed and your vet believes improving motility could help.

For cockatiels, metoclopramide is usually not a stand-alone fix. Slow crop emptying, regurgitation, or gastrointestinal stasis can happen for many reasons, including dehydration, infection, inflammation, foreign material, heavy metal toxicity, or neurologic disease such as proventricular dilatation disease. That is why your vet will usually pair this medication with an exam and, when needed, crop cytology, imaging, bloodwork, fluids, or crop flushing.

This drug is considered extra-label in veterinary patients and is not specifically labeled for birds. That is common in avian medicine, but it means dosing and monitoring need to be individualized. Your vet may choose an oral, injectable, or compounded form depending on your cockatiel's size, hydration status, and whether the bird is still safely swallowing.

In cockatiels, metoclopramide is most often discussed when there is concern about crop stasis or slowed upper GI motility. Avian emergency references describe it as one option that may improve motility after the crop has been emptied if needed, the bird has been rehydrated, and a blockage is not suspected. It may also be used when a bird is regurgitating or appears nauseated, but only after your vet has looked for the reason those signs started.

Your vet may consider metoclopramide as part of treatment for delayed crop emptying associated with dehydration, systemic illness, crop inflammation, or generalized gastrointestinal slowdown. It is not appropriate for every bird with a full crop. If a foreign body, severe infection, bleeding, perforation, or obstruction is present, pushing the gut to move can be risky.

Because crop stasis is a symptom, not a diagnosis, metoclopramide works best when it is part of a broader plan. That plan may include warmth, fluids, assisted feeding, crop lavage, antifungal or antibacterial therapy when indicated, heavy metal testing, radiographs, and close rechecks. For many cockatiels, the most important question is not whether to use a motility drug, but why the crop slowed down in the first place.

Never dose metoclopramide in a cockatiel without your vet's instructions. Birds are small, sensitive patients, and even tiny measuring errors matter. Avian references describe metoclopramide being used around 0.5 mg/kg IM every 8 to 12 hours as needed for gastrointestinal stasis, while one avian text notes that 0.1 mg/kg PO or IM has been used without hyperexcitability in some birds. Those numbers are not a home-dosing guide. They are examples of why your vet must tailor the plan to the individual bird, route, and clinical problem.

Your vet may adjust the dose based on body weight, hydration, kidney function, neurologic history, and whether the goal is anti-nausea support or motility support. In many cockatiels, a compounded liquid is needed so the volume is small enough to measure accurately. If your bird vomits, is too weak to perch, has a distended crop, or is not passing droppings normally, do not keep redosing at home. See your vet immediately.

Ask your vet exactly how much to give, how often, whether to give with food, and what signs mean the medication should be stopped. If you miss a dose, contact your vet for instructions rather than doubling the next one. With birds, the safest plan is always the most precise one.

Metoclopramide can affect both the digestive tract and the nervous system. In companion animals, reported side effects include restlessness, hyperactivity, twitching or spasms, drowsiness, constipation, and behavior changes. Avian references add an important caution: seizures and hyperexcitability have been reported in some birds at higher doses. That makes careful dosing especially important in cockatiels.

Call your vet promptly if your cockatiel seems unusually agitated, weak, sleepy, off balance, or starts showing tremors, repetitive movements, or worsening regurgitation. Also watch for a crop that stays enlarged despite treatment, reduced droppings, or a bird that stops eating. Those signs may mean the underlying problem is progressing rather than improving.

See your vet immediately if your cockatiel is open-mouth breathing, cannot stay on the perch, has repeated vomiting, has a very distended crop, or seems neurologically abnormal. In birds, these changes can become serious fast. A medication side effect and a worsening GI emergency can look similar, so rapid reassessment matters.

Metoclopramide can interact with other medications, so your vet should know about every prescription, supplement, probiotic, and over-the-counter product your cockatiel is receiving. Veterinary references for companion animals list caution with drugs such as antihistamines, barbiturates, certain anesthetics, antidepressants, cholinergic drugs, cyclosporine, mirtazapine, selegiline, tramadol, cephalexin, and tetracyclines. Some of these may increase sedation or neurologic effects, while others may change how drugs move through the digestive tract and are absorbed.

The biggest practical concern in birds is that metoclopramide should not be used casually when there may be a mechanical obstruction, GI bleeding, or perforation. In those situations, increasing motility can make a dangerous problem worse. Anticholinergic medications may also counteract its prokinetic effect.

If your cockatiel is scheduled for sedation, anesthesia, imaging with contrast, or treatment for infection, tell your vet that metoclopramide has been given and when the last dose was used. That helps your vet choose the safest combination of therapies and decide whether this medication still fits the case.
