Sucralfate for Macaws: Uses, Dosing & 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.

Sucralfate is a gastrointestinal protectant. It is not an antibiotic and it does not reduce stomach acid directly. Instead, it forms a sticky protective coating over irritated tissue and ulcerated areas in the mouth, esophagus, crop, stomach, or intestines. That barrier helps shield damaged tissue from acid, digestive fluids, and ongoing irritation while healing takes place.

In birds, including macaws, sucralfate is used extra-label, which means your vet is prescribing it based on veterinary evidence and clinical experience rather than a bird-specific FDA label. This is common in avian medicine. Because macaws vary widely in size, hydration status, appetite, and underlying disease, the right plan depends on the individual bird.

Macaws often do best with a liquid or slurry form because tablets can be hard to dose accurately in birds. Your vet may have you give it by mouth before food or hand-feeding formula so it can contact the irritated tissue well. If your macaw is already stressed, weak, or regurgitating, ask your vet whether a compounded suspension would make treatment safer and easier.

Your vet may use sucralfate in a macaw to support healing of esophageal, crop, or gastrointestinal irritation. In avian references, it is listed as an esophageal, crop, and gastrointestinal protectant. That makes it a common add-on medication when the lining of the digestive tract is inflamed, ulcerated, or painful.

Situations where your vet might consider sucralfate include crop burns, esophagitis, ulceration, irritation after regurgitation, medication-related GI injury, or suspected upper digestive tract inflammation. It may also be used alongside other treatments when a bird has reduced appetite because swallowing appears painful.

Sucralfate does not fix the underlying cause by itself. If a macaw has heavy metal exposure, infection, foreign material, severe reflux, toxin exposure, or another systemic illness, your vet may pair sucralfate with diagnostics and other medications. Think of it as a protective support medication, not a stand-alone cure.

In avian formularies, sucralfate is commonly listed at 25 mg/kg by mouth every 8 hours for psittacine birds, including parrots and macaws. Some avian references also note that birds may regurgitate with oral medications, and dose adjustments may be needed in sensitive individuals. Your vet may choose a different schedule based on your macaw's weight, diagnosis, appetite, and how well the medication is tolerated.

Sucralfate is usually given on an empty stomach and separated from other oral medications by at least 2 hours because it can bind other drugs and reduce absorption. Tablets are often crushed and mixed with a small amount of water to make a slurry. Liquid suspensions should be shaken well before use. Never change the concentration or volume on your own, because a small measuring error matters much more in birds than in dogs or cats.

If you miss a dose, contact your vet for guidance. In many cases, they will have you give it when remembered unless it is close to the next scheduled dose. Do not double up. If your macaw spits out, regurgitates, or aspirates medication, stop and call your vet before repeating the dose.

Sucralfate is generally considered well tolerated, but side effects can still happen. Across veterinary sources, the most commonly reported problems are constipation, vomiting, and drooling. In a macaw, you may notice reduced droppings, straining, tackier urates, lip-smacking, head shaking after dosing, or reluctance to swallow.

Because birds can hide illness, watch for subtle changes too: less interest in food, quieter behavior, fluffed feathers, repeated regurgitation, or weight loss. These signs may reflect the underlying digestive problem, trouble taking the medication, or dehydration rather than the drug alone.

See your vet immediately if your macaw has ongoing vomiting or regurgitation, trouble breathing after dosing, marked lethargy, black or bloody droppings, severe decrease in droppings, or sudden weakness. Those signs can point to a more serious GI problem or a dosing/administration issue that needs prompt care.

The biggest interaction concern with sucralfate is that it can bind other oral medications and reduce how much of them the body absorbs. Veterinary sources recommend not giving it within 2 hours of other medications. This matters in macaws because many birds taking sucralfate are also on antibiotics, antifungals, pain medication, prokinetics, or acid-control drugs.

Examples of medications your vet may want spaced away from sucralfate include oral antibiotics, antifungals, thyroid medications, and some stomach medications. If your macaw is on several drugs, ask your vet to map out an exact schedule. A written chart can prevent accidental overlap.

Also tell your vet about supplements, hand-feeding products, probiotics, and over-the-counter human medications. Even if a product seems mild, timing can affect absorption. Never add another medication to the same syringe unless your vet specifically says it is safe.
