Where should ephedrine and pseudoephedrine, when used as the sole active ingredient, be stored?

Ephedrine and pseudoephedrine are classified as listed chemicals under various regulations due to their potential for misuse in the illegal synthesis of methamphetamine. Consequently, their storage requires special attention to prevent diversion and ensure these substances are less accessible to individuals who might misuse them.

Storing ephedrine and pseudoephedrine in a locked display case or behind a counter aligns with the regulations and best practices aimed at controlling their distribution. This secure storage method minimizes the risk of theft and unauthorized access, ensuring that these products are only available to consumers who meet legal requirements, such as age restrictions or purchasing limits.

In contrast, an open shelf or any easily accessible location would not provide adequate security and could lead to increased potential for abuse. Storing these substances in a pharmacy refrigerator is also unsuitable, as their storage conditions do not require refrigeration, and it would unnecessarily complicate inventory management.

Thus, the correct approach to storing ephedrine and pseudoephedrine ensures compliance with legal standards and maintains public safety.
