What is famotidine?<\/span><\/h2>\n

Famotidine<\/span><\/a> belongs to a class of drugs called histamine H2-receptor antagonists, or <\/span>H2 blockers<\/span><\/a> for short. H2 blockers are popular over-the-counter medications found in every drug store and supermarket under brand names like <\/span>Tagamet<\/span><\/a> (cimetidine), <\/span>Pepcid<\/span><\/a> (famotidine), and <\/span>Zantac<\/span><\/a> (ranitidine). They help people with <\/span>heartburn<\/span><\/a>, GI inflammation, <\/span>ulcers<\/span><\/a>, and gastroesophageal reflux disease (<\/span>GERD<\/span><\/a>). Although they\u2019re a type of antihistamine, they only block a type of histamine receptor found in the stomach linked to stomach acid production. Reducing stomach acid relieves symptoms and allows tissues in the stomach, esophagus, or small intestine to heal. They work the same way in dogs as in humans.<\/span><\/p>\n

What is famotidine used for in dogs?<\/span><\/h2>\n

Famotidine<\/span><\/a> reduces stomach acid secretion in dogs with stomach acid problems, such as ulcers, inflammation, acid reflux, and vomiting. Veterinarians also prescribe it when they\u2019re concerned a dog may develop ulcers or inflammation of the esophagus or stomach, such as when a dog is being treated with an <\/span>NSAID<\/span><\/a>, vomiting frequently, or having problems with acid reflux.\u00a0<\/span><\/p>\n

The veterinary use of famotidine is <\/span>off-label<\/span><\/a>, meaning the Food and Drug Administration (FDA) has not approved it for use in dogs or other animals. This is a common practice in veterinary medicine.<\/span><\/p>\n

Famotidine for ulcers<\/span><\/h3>\n

Dogs, like humans, can develop ulcers due to <\/span>various factors<\/span><\/a> such as stress, kidney disease, liver disease, extreme exercise, medication side effects, and inflammatory conditions. The incidence of ulcers in dogs is unknown, but it\u2019s a common problem in veterinary practice.\u00a0<\/span><\/p>\n

Pet owners cannot identify whether or not a dog has an ulcer specifically, but it will be obvious that there\u2019s a problem. The most common signs of an ulcer in a pet are:<\/span><\/p>\n
