You must be at least how old to buy pseudoephedrine?

To purchase pseudoephedrine, an individual must be at least 18 years old. This age requirement is a part of regulations aimed at controlling the sale of products containing pseudoephedrine due to its potential for misuse in manufacturing methamphetamine. The restriction is designed to help curb illegal activities while still allowing legitimate access to medications containing this ingredient for treating nasal and sinus congestion.

Retailers must verify the age of the buyer, ensuring compliance with the established law. This age limit reflects a balance between public health concerns and providing access to over-the-counter medications.
