Which of the following could lead to patients taking more medication than prescribed?

The correct choice regarding factors that could lead patients to take more medication than prescribed is when the prescriber increased the dose. This situation directly affects the patient's medication regimen, as a higher dosage may be intended to address an ongoing health issue more effectively. However, if a patient is not properly informed about the change or misunderstands the instructions, they might inadvertently exceed their prescribed dosage based on the new directive, thinking that taking more is necessary or permissible.

In contrast, the other scenarios may influence compliance or perception of medication but do not directly result in taking more than prescribed. Disliking their doctor might lead to non-compliance or reluctance to discuss medication needs but does not inherently encourage increased dosages. Forgetting last doses typically results in missed doses rather than increased intake. Lastly, enjoying the effects of the medication may lead to the temptation to take more, but without explicit direction from the prescriber, it is less likely to manifest as a change in the prescription itself.
