Which type of prescription requires special handling because of its potential for abuse?

Controlled substances require special handling due to their potential for abuse and addiction. These substances are categorized into schedules based on their medical use, safety, and potential for abuse. Schedule I substances have no accepted medical use and the highest potential for abuse, while Schedule V substances have accepted medical uses but still carry some risk. Because of their potential for misuse, controlled substances are subject to strict regulations regarding their prescription, dispensing, and record-keeping. This ensures that they are not easily accessible and reduces the risk of addiction and illegal distribution. The other categories, such as over-the-counter medications, herbal supplements, and prescription vitamins, do not have the same level of regulatory oversight as controlled substances due to their lower risk of abuse.
