What requirement must be met for pseudoephedrine to be displayed in stores without being behind the counter?

For pseudoephedrine to be displayed in stores without being behind the counter, it is essential that these products have anti-theft devices. This requirement is in place due to the potential for misuse of pseudoephedrine in the illegal production of methamphetamine. The implementation of anti-theft devices helps to deter theft and misuse while allowing for easier access to the product for customers who need it for legitimate medical purposes.

This focus on security safeguards ensures that while the product is accessible, it is also protected from potential abuse. The other options, such as clear labeling, locked cabinets, or monitoring by security personnel, do not sufficiently address the specific requirement linked to making pseudoephedrine accessible in retail environments while still ensuring regulatory compliance and safety.
