Which of these actions indicates non-adherence to prescribed pharmacologic therapy?

C is the correct choice because sharing medication with others constitutes a significant breach of adherence to prescribed pharmacologic therapy. Each medication is typically prescribed considering an individual’s specific health needs, conditions, and tolerances. Sharing medication can lead to inappropriate use, potential adverse effects, and exacerbation of health issues, undermining the therapeutic intentions of prescribed treatments.

In contrast, taking all medications as prescribed on a scheduled basis, following a medication schedule strictly, and utilizing a pharmacy for prescription deliveries are actions that align with adherence. These behaviors reflect a commitment to following healthcare guidelines, ensuring medications are taken properly, and maintaining consistent access to prescribed therapies.
