What is pseudoephedrine?
Pseudoephedrine (PSE) is an FDA-recognized safe and effective decongestant ingredient that was commonly used in many cough, cold, and flu products until regulations prohibited its use in direct-access over-the-counter (OTC) products in 2006. Current regulations limiting OTC access to PSE products were enacted to restrict availability to persons who would use them to manufacture the illegal drug methamphetamine. PSE products are now sold behind the pharmacy counter and are safe and effective when used as directed.
Is PSE safe?
PSE is safe when used as directed. It is important to note that the safety of PSE has been well established. The controversy surrounding PSE is limited to a product misuse/abuse issue.
How does PSE work?
PSE works by constricting blood vessels in the nose in order to decrease blood flow to the area and open air passageways.
