What defines Schedule II medications?

Schedule II medications are classified as having a high potential for addiction and abuse, which is why they are subject to strict regulations. These medications can lead to severe psychological or physical dependence, and their use is controlled by federal and state laws. This category includes powerful narcotics and stimulants typically prescribed for conditions like severe pain or attention deficit hyperactivity disorder (ADHD), among others. Because of the risks associated with their use, medical professionals must adhere to rigorous guidelines when prescribing these medications, ensuring that they are used safely and appropriately.

The other options do not accurately describe Schedule II medications. There are no over-the-counter medications that fit this classification. Additionally, Schedule II medications are specifically distinguished by their high potential for abuse, which directly contradicts the definition of medications with low potential for addiction and abuse. Furthermore, while some might be used in life-threatening situations, this is not a defining characteristic of all Schedule II medications. The crux of their classification lies in their risk for addiction and regulation rather than their application in specific medical conditions.
