What is the daily purchase limit of pseudoephedrine without a prescription?

The daily purchase limit for pseudoephedrine without a prescription is 3.6 grams. This regulation is established to control the sale of pseudoephedrine, a precursor often used in the illicit manufacture of methamphetamine. The 3.6 grams limit applies to the quantity that an individual is allowed to purchase in a single day, regardless of whether these purchases occur at one pharmacy or multiple locations within that day.

This limit is consistent across many states and is enforced to prevent excessive purchases that could be used for illicit drug production. The requirement allows for tracking and monitoring purchases while still permitting access for legitimate medical use, such as for treating nasal congestion. Understanding this limit is crucial for compliance with both federal and state regulations regarding pseudoephedrine sales.
