Final answer:
Individuals taking Coumadin should avoid increasing the intake of broccoli due to the vitamin K content that affects the drug's efficacy. Pharmacogenomics can assist by providing personalized dosage and dietary plans based on the patient's genetic information.
Step-by-step explanation:
When taking Coumadin, a drug frequently given to prevent excessive blood clotting, you should avoid increasing your intake of broccoli (Option C). Coumadin, also known as warfarin, is affected by dietary intake of vitamin K, which is prevalent in green leafy vegetables like broccoli. Vitamin K plays a crucial role in blood clotting, and thus, a consistent intake is necessary to maintain stable drug effectiveness. If a patient significantly increases their consumption of vitamin K-rich foods, it can reduce the effectiveness of Coumadin and potentially lead to a risk of blood clots.
Utilizing pharmacogenomics can greatly assist patients taking Coumadin by providing personalized drug treatment plans based on genetic testing. It can enable precise dosage adjustments and a tailored dietary plan to manage the patient's response to Coumadin, taking into consideration their liver function and other metabolic factors unique to their genetic makeup. This can help in preventing both overdose and underdose of the medication.
