Sucralfate for Dogs and Cats

What Is Sucralfate for Dogs and Cats

Overview

Sucralfate is a medication that works by forming a protective, gel-like coating over damaged areas in the stomach and intestines. This coating shields the injury from stomach acid, digestive enzymes, and bile salts. It is commonly prescribed for gastrointestinal ulcers, gastritis, and erosive GI conditions in both dogs and cats.
Veterinarians also use Sucralfate to support healing when pets are vomiting or experiencing diarrhea, especially when the GI lining is inflamed or damaged. It is a well-tolerated and widely used GI protectant due to its gentle action and minimal systemic absorption.

What Is Sucralfate for Dogs and Cats Used For

Sucralfate binds to exposed proteins at ulcer or injury sites and forms a thick, sticky protective layer. This protective coat shields the tissue from acid, digestive enzymes, and bile, allowing the cells underneath to heal. It also increases local blood flow and supports natural repair processes.

Drug Facts

Sucralfate is a gastroprotectant that is minimally absorbed into the bloodstream. It is made of sucrose sulfate combined with aluminum hydroxide, which together create a gel-like protective coating when exposed to stomach acid. Sucralfate helps heal damaged tissue by blocking irritation and enhancing recovery.

Sucralfate for Dogs and Cats Dosage Forms

Sucralfate comes in tablet form and liquid suspension. Tablets can be crushed and mixed with water to form a slurry, which is often easier for pets to swallow. Liquid formulations coat the GI tract more effectively and are preferred for animals with severe ulceration or esophagitis.
Veterinarians may also use topical sucralfate slurries for oral or esophageal injuries because the medication adheres well to mucosal surfaces.
