주의사항 및 금기

• Known hypersensitivity to H2 blockers

• Use cautiously in **geriatric patients** and those with significantly **impaired hepatic or renal function**; consider dosage reduction in patients with significant renal dysfunction. Famotidine may have negative inotropic effects and some cardioarrhythmogenic properties; use with caution in patients with **cardiac disease**. When administering IV to cats, infuse slowly (over 5 minutes) to minimize the rare risk of intravascular hemolysis.

약물 상호작용

• Azole Antifungals (ketoconazole, itraconazole, fluconazole): Famotidine raises gastric pH, which may decrease the absorption of these agents. Administer the azole one hour prior to famotidine.
• Cefpodoxime, Cefuroxime: Famotidine may decrease the absorption of these cephalosporins. Taking with food may alleviate this effect.
• Iron Salts (Oral): Famotidine may decrease the absorption of oral iron. Administer iron at least one hour prior to famotidine.
