1. What Is Sucralfate & How Does It Work?

Sucralfate is a mucosal protectant that creates a viscous paste by reacting with stomach acid. This paste adheres to ulcers in the esophagus, stomach, and upper small intestine, forming a protective barrier to promote healing :contentReference[oaicite:3]{index=3}.

Although FDA-approved for humans (brand Carafate®), its use in dogs and cats is off-label but well-established :contentReference[oaicite:4]{index=4}.

2. Common Veterinary Uses

• Treatment and prevention of ulcers in the oral cavity, esophagus, stomach, and duodenum :contentReference[oaicite:5]{index=5}.
• Management of esophagitis and gastric irritation from NSAIDs, steroids, or toxins.
• Occasional use as a phosphate-binder in kidney disease :contentReference[oaicite:6]{index=6}.

3. Dosage & Administration Guidelines

• Typically given every 6–12 hours.
• Standard dosing: small dogs/cats 0.25–0.5 g; medium/large dogs up to 1 g per dose :contentReference[oaicite:7]{index=7}.
• For tablets, crush and mix into water to create a slurry; shake liquid suspension before use :contentReference[oaicite:8]{index=8}.
• Administer on an empty stomach—30–60 min before meals, or two hours after food or other meds :contentReference[oaicite:9]{index=9}.

Missed doses? Give as soon as remembered unless next dose is due—avoid doubling doses :contentReference[oaicite:10]{index=10}.
