Which schedule is stringently restricted and requires written prescriptions?

• A. Schedule I
• B. Schedule II
• C. Schedule III
• D. Schedule IV

Answer: (B)

Tight control of prescription drugs is the core idea here. The schedule that is described as stringently restricted and requiring a written prescription is the one associated with the highest level of prescription control for drugs that do have medical uses. These substances have a high potential for abuse and dependence, so dispensing them is governed by strict rules: a prescription must be written and signed by a licensed prescriber, and there are often limits on refills and additional safeguards. This is why that schedule is considered the most restricted in terms of how it can be prescribed and dispensed.

By comparison, substances in other schedules have medical uses with looser restrictions. For example, the schedule with no accepted medical use is not prescribed at all in standard practice. The schedules with medical uses allow more flexible prescribing, including verbal orders in many cases and multiple refills within set limits, making them less stringently controlled than the one described.

So the described situation points to the schedule with the highest prescription-control requirements, where a written prescription is mandatory.
