What is the maximum amount of pseudoephedrine that can be sold over the counter in one day?

The regulation surrounding the sales of pseudoephedrine at the federal level limits the amount that can be sold to an individual in a single day to 3.6 grams. This rule is designed to prevent the misuse of pseudoephedrine in the production of methamphetamine, a serious public health concern.

In practice, this means that regardless of whether a person is purchasing pseudoephedrine in a single transaction or through multiple transactions within a 24-hour period, the cumulative total cannot exceed 3.6 grams. The requirement for identification and the recording of purchases in a logbook further reinforce efforts to monitor and control access to this substance.

Understanding this regulation is crucial for pharmacy practice as it ensures compliance with the law while also contributing to public safety.
