Final answer:
Combining warfarin with atorvastatin may increase bleeding risk due to potential drug interactions, which requires careful medical monitoring. Pharmacogenomics helps in personalizing warfarin doses by assessing genetic factors affecting drug metabolism.
Step-by-step explanation:
Taking warfarin with atorvastatin may increase the risk of bleeding due to warfarin's action as a blood thinner. Atorvastatin, a statin used for cholesterol management, can potentially interfere with the metabolism of warfarin, leading to higher levels of warfarin in the blood. This interaction can be dangerous and requires careful monitoring by healthcare providers.
Pharmacogenomics can play a critical role in personalizing treatment for patients on medications like warfarin. It involves analyzing genetic factors that affect a person's response to drugs. For patients with variations in liver enzymes that metabolize warfarin, pharmacogenomic testing can guide dosage adjustments to prevent overdose and ensure efficacy of the treatment.
