Final answer:
Pharmacogenomics can determine the most effective dosage of Coumadin for individual patients to reduce the risk of overdose or underdose.
Step-by-step explanation:
Pharmacogenomics can be used to assist patients who are taking Coumadin to prevent excessive blood clotting. By studying the patient's genetic profile, pharmacogenomics can help determine the most effective dosage of Coumadin for individual patients. This personalized approach can reduce the risk of overdose or underdose and ensure that the medication is optimally effective for each patient.
