Which type of medication must always have a prescriptive order before administration?

Controlled substances are medications that are regulated by law due to their potential for misuse or addiction. These substances have specific scheduling classifications that determine their legality and prescribe them.

Before a healthcare provider can administer any controlled substance, they must have a detailed prescriptive order from a qualified medical professional. This ensures proper monitoring and regulation of such drugs, which can lead to serious health consequences if misused. Controlled substances include medications like opioids, certain sedatives, and stimulants, and because of their classification, it is crucial that their use is authorized and supervised to prevent abuse.

In contrast, over-the-counter medications, herbal supplements, and physician-recommended vitamins do not require a prescriptive order before administration. These types of substances are generally deemed safe for consumer use without a prescription, although it is still advisable to consult a healthcare provider to ensure they are appropriate for an individual's health conditions.
