Which of the following is a correct daily limit for Pseudofed sales?

The correct daily limit for the sale of Pseudofed (pseudoephedrine) is 3.6 grams. This limit is in accordance with federal regulations established to manage the sale of pseudoephedrine, as it is a precursor in the manufacturing of methamphetamine.

This regulation was enacted to prevent misuse and ensure that individuals using pseudoephedrine for legitimate medical purposes have access while also limiting opportunities for abuse. The daily limit reflects a balance between availability for consumers needing relief from nasal congestion and regulatory measures to combat illegal drug production.

The other options suggest higher daily sales limits which do not comply with federal regulations. Maintaining awareness of these limits is critical for pharmacists and those involved in the sale of over-the-counter medications containing pseudoephedrine to ensure they are in line with the law and protect public health.
