Is pseudoephedrine available over-the-counter in the United States?

Pseudoephedrine is sold in over-the counter drugs that are regulated by strict FDA requirements concerning where they are stored, daily limits for individuals and record keeping that stores buyer's information for two years. The drug has been used illegally in the past to make methamphetamine, a powerful addictive drug, according the FDA.

The FDA's requirements state that all non-prescription drugs containing pseudoephedrine are to be stored behind the counter in a locked cabinet, according to Sudafed´s website. A photo ID is necessary to purchase the popular sinus pain and congestion reliever, and a logbook is kept of all purchases as well as the frequency of those purchases.
