Famotidine reduces stomach acid production and treats ulcers, gastritis (uremic, erosive), and gastroesophageal reflux. Veterinarians supervise its use, especially for animals with specific conditions or those taking azole antifungals. This medication often causes digestive issues such as loss of appetite or vomiting. In rare cases, it may lead to kidney problems or blood pressure changes. Regularly monitor your animal’s condition and consult a veterinarian if side effects occur. Store famotidine away from light and out of reach of children. Never change or discontinue the treatment without consulting your veterinarian.
