Propylhexedrine (Benzedrex, Obesin) is a stimulant drug that is used medicinally as a nasal decongestant (for relief of congestion due to colds, allergies and allergic rhinitis) and recreationally for its psychostimulant effects. Being a vasoconstrictor used to decongest nasal mucosa, it is administered by inhalation.
