Answer and Explanation

A. Valerian is an herbal supplement commonly used for its sedative effects. It does not have a significant interaction with warfarin and is not contraindicated for concurrent use.
B. Probiotics are generally safe to use with warfarin and do not have a significant impact on its anticoagulant effects. They are not contraindicated for concurrent use.
C. Ginkgo biloba is known to increase the risk of bleeding when taken with warfarin. It has antiplatelet effects that can enhance the anticoagulant effects of warfarin, leading to an increased risk of bleeding complications. Therefore, it is contraindicated for concurrent use with warfarin.

Correct Answer is B

Explanation

A. Return the remaining medication to the facility’s pharmacy. This action is not appropriate because it is not standard practice to return partially used medications to the pharmacy.

C. Store the remaining half of the pill in the automated medication dispensing system. This action is not appropriate because storing a half tablet in the dispensing system can lead to contamination and dosing errors.
D. Place the remaining half of the pill in the unit-dose package. This action is not appropriate because it does not ensure proper disposal and could lead to medication errors or misuse.
