Which of the following is a potential topic of patient education related to medications?

Focusing on the medication's possible side effects and interactions is crucial for patient education because it empowers patients to understand what to expect from their treatment. When patients are informed about potential side effects, they can recognize adverse reactions early and seek appropriate care when needed. Additionally, understanding drug interactions can help prevent complications that may arise from simultaneous use of multiple medications. This knowledge enhances medication adherence and encourages patients to engage actively in their own healthcare management.

While other topics, such as the history of the drug's approval, the psychological effects of the medication, and the cost of the medication, may have their importance in specific contexts, they do not provide as immediate a benefit to the patient in terms of safely using the medication. The priority in patient education should be on practical information that directly affects health and safety.
