Cisapride for Geese: Uses, Dosing & GI Motility Support

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.

Cisapride is a prescription prokinetic medication. That means it helps the digestive tract move food and fluid forward more effectively. In veterinary medicine, it is used to support motility in the esophagus, stomach, small intestine, and colon. It is not an antibiotic, pain medication, or anti-nausea drug.

For geese and other birds, cisapride is an extra-label medication. Your vet may consider it when a goose has slowed gastrointestinal movement and an obstruction, perforation, or active GI bleeding has been ruled out. In the United States, cisapride is generally obtained through a compounding pharmacy, so the exact concentration and flavor may vary.

Because geese are food-producing animals, medication decisions can be more complex than they are for dogs and cats. Your vet may need to discuss meat or egg withdrawal considerations, recordkeeping, and whether cisapride is appropriate for your bird's role and intended use.

Cisapride is used to support reduced GI motility. In birds, that may include crop stasis, delayed gastric emptying, postoperative ileus, or generalized gastrointestinal slowdown as part of a larger treatment plan. It is usually not the whole answer. Your vet will also look for the reason motility slowed in the first place, such as dehydration, infection, heavy metal exposure, foreign material, reproductive disease, pain, or systemic illness.

In avian emergency and critical care references, cisapride has been described as a GI stimulant that may help when obstruction is not suspected and supportive care is already underway. That often means fluids, crop management, nutrition support, warmth, and diagnostics are addressed alongside the medication.

For pet parents, the key point is this: cisapride may help the gut move, but it does not fix a blockage or replace a full workup. If your goose is straining, vomiting or regurgitating repeatedly, passing very little stool, acting weak, or has a swollen painful abdomen, see your vet promptly.

See your vet immediately if your goose has severe lethargy, repeated regurgitation, abdominal distension, suspected toxin exposure, or little to no droppings. Cisapride should only be used after your vet has assessed whether the digestive tract should be stimulated at all.

Published avian references commonly list cisapride at 0.5-1.5 mg/kg by mouth every 8 hours for gastrointestinal stasis support in birds. That said, geese vary widely in body size, hydration status, underlying disease, and how well they tolerate oral medication. Your vet may choose a lower starting dose, a different interval, or a different formulation based on the clinical picture.

Because cisapride is usually compounded, dosing errors can happen when concentrations differ between pharmacies. Ask your vet to write the dose in both mg and mL, and confirm the bottle strength before each refill. If a dose is missed, contact your vet for instructions. Do not double the next dose unless your vet specifically tells you to do so.

Many birds need more than medication alone. Fluids, crop emptying when indicated, assisted feeding, imaging, fecal or crop testing, and treatment of the underlying cause often matter as much as the prokinetic itself.

Mild side effects are usually gastrointestinal. A goose may develop looser droppings, increased stool output, abdominal discomfort, or vomiting/regurgitation. Some birds also become stressed by handling or dislike the taste of compounded liquid, which can make it harder to tell whether the medication or the dosing process is the problem.

More serious reactions are uncommon but matter. Veterinary references warn about incoordination, excessive drooling, muscle twitching, agitation, abnormal behavior, increased body temperature, and seizures, especially if the dose is too high or the bird has another medical problem that changes how the drug is handled.

Cisapride should be used cautiously, or avoided, in patients with GI obstruction, perforation, bleeding, severe liver disease, or abnormal heart rhythms. If your goose seems weaker after starting the medication, stops passing droppings, develops neurologic signs, or the abdomen becomes more distended, contact your vet right away.

Cisapride has some of its most important safety concerns around heart rhythm interactions. Drugs that can prolong the QT interval or affect cardiac conduction may raise risk when combined with cisapride. Veterinary references also advise caution with certain macrolide antibiotics, azole antifungals, fluoroquinolones, amiodarone, procainamide, quinidine, sotalol, tricyclic antidepressants, cimetidine, chloramphenicol, cyclosporine, ondansetron, opioids, benzodiazepines, furosemide, and anticholinergic drugs.

Some interactions are pharmacologic, and some are practical. Anticholinergic drugs and opioids can slow GI movement, which may work against the reason cisapride was prescribed. Other medications may change how cisapride is metabolized, increasing the chance of adverse effects.

Tell your vet about everything your goose is receiving, including supplements, probiotics, electrolytes, pain medications, dewormers, and any drugs prescribed for the rest of the flock. If your goose lays eggs or may enter the food chain, ask specifically about withdrawal guidance and whether an alternative plan would be safer.
