What is the proper procedure if a customer attempts to buy excessive pseudoephedrine?

The correct answer involves blocking the sale via the National Precursor Registry Electronic Report System (NPLEx). This system is designed to monitor the purchase of pseudoephedrine, a precursor ingredient often used in the illicit manufacture of methamphetamine. When a pharmacy utilizes NPLEx, it allows for tracking of pseudoephedrine sales and helps prevent individuals from exceeding the legal limits set by federal and state regulations.

If a customer attempts to buy an excessive amount of pseudoephedrine, using NPLEx enables the pharmacy to check the customer's purchase history and determine if they are attempting to bypass the legal restrictions. By blocking the sale in compliance with the requirements of NPLEx, the pharmacy is fulfilling its legal obligations and contributing to efforts to thwart drug abuse.

While reporting to local authorities could seem appropriate, it is generally a secondary step that may not be necessary unless there is immediate evidence of illegal activity. Ignoring the situation would violate pharmacy regulations and potentially contribute to illegal drug production. Providing educational materials on limitations might raise awareness, but it does not prevent the immediate issue of the excessive sale. Therefore, employing NPLEx to block the sale is the most effective and compliant course of action.
