What is a common consequence of an "unintentional effect" when taking medication?

An "unintentional effect" of medication typically refers to any outcome that occurs as a result of taking the medication but is not the desired therapeutic effect. This often leads to adverse reactions. Adverse reactions can range from mild side effects, like drowsiness or nausea, to more severe effects that may require medical attention. These unintended consequences are important to monitor, as they can significantly impact a patient's overall well-being and treatment adherence.

Options like improved health, increased effectiveness, and proper dosage are all related to positive outcomes or correct therapeutic intentions, rather than the unintended or adverse effects. In the context of medication administration and patient safety, recognizing and managing adverse reactions is crucial for effective care.
