An alternative to Eliquis (apixaban) for patients with renal disease is warfarin, but it requires careful monitoring of INR levels due to increased risks of bleeding and requires dietary considerations.
- Warfarin is a vitamin K antagonist that is commonly used as an alternative anticoagulant for patients with renal impairment when newer oral anticoagulants like Eliquis are contraindicated or need to be avoided. 
- Regular monitoring of the International Normalized Ratio (INR) is crucial in patients on warfarin, especially in those with renal disease, to avoid over-anticoagulation and associated bleeding risks. 
- Patients on warfarin need to maintain a consistent intake of vitamin K through their diet, as fluctuations can affect INR levels and the effectiveness of the drug. 
- Warfarin interacts with many other medications and foods, and these interactions can affect its anticoagulant effect, necessitating adjustments in dosage. 
- The initiation of warfarin therapy in patients with renal disease should be approached with caution, and dose adjustments may be necessary based on INR results and renal function.
