Cimetidine (Tagamet®)
Veterinary & Aquatic Services Department, Drs. Foster & Smith

Cimetidine is in a class of drugs called H2 receptor antagonists. It is used to decrease the amount of stomach acid produced in dogs, cats, and other pets. This aids in the treatment of ulcers that are present and helps prevent ulcer formation. It is also used in the treatment of gastritis (inflammation of the stomach), esophagitis (inflammation of the esophagus), and gastric or esophageal reflux. Use with caution in animals who are older, have blood abnormalities, or those with liver or kidney disease. Side effects are rare. Contact your veterinarian if your pet has a rapid heart rate or difficulty breathing while being treated with cimetidine. Cimetidine may influence the absorption or metabolism of many other oral medications, so consult your veterinarian before using cimetidine with other medications.
