What is PSE?

Pseudoephedrine—or PSE—is an active ingredient found in many over–the–counter (OTC) medicines like Advil® Cold & Sinus, Allegra-D®, Claritin-D®, Mucinex® D, Zyrtec-D® and Sudafed®. PSE provides convenient, effective treatment for congestion due to colds, allergies and sinus problems.

In 2010, more than 18 million American households relied on OTC medicines containing PSE for their cold, sinus and allergy symptoms.1

PSE is also the only OTC decongestant that provides 12-hour and 24-hour relief.
