給藥方式

可能的副作用

• Mild GI upset
• Anorexia
• Weight loss
• Diarrhea
• Vomiting (especially associated with IV injections)

注意事項與禁忌

• Ventricular fibrillation
• Digitalis intoxication
• Hypertrophic cardiomyopathy in cats (relative contraindication, may increase myocardial oxygen demand and dynamic outflow obstruction)
• Frequent ventricular arrhythmias
• Atrioventricular (AV) block
• Feline hypertrophic cardiomyopathy
• Hypokalaemia
• > **Extreme Caution:** Patients with glomerulonephritis and heart failure, or with idiopathic hypertrophic subaortic stenosis (IHSS). * **Caution:** Severe pulmonary disease, hypoxia, acute myocarditis, myxedema, acute myocardial infarction, frequent VPCs, V-tach, chronic constrictive pericarditis, or incomplete AV block. * **Renal Disease:** Principally eliminated by the kidneys; use with caution and monitor serum levels closely in patients with renal impairment. * **Electrolyte/Endocrine Imbalances:** Animals that are hypernatremic, hypokalemic, hypercalcemic, hyper- or hypothyroid may require smaller dosages; monitor carefully. * **Cardioversion:** Elective cardioversion of patients with atrial fibrillation should be postponed until digoxin has been withheld for 1-2 days. * **Dosing Weight:** Dosing is generally based upon **lean body weight** as digoxin does not distribute well into ascitic fluid or fat.
