Pseudoephedrine Hcl is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
Pseudoephedrine Hcl is used to treat nasal and sinus congestion, or congestion of the tubes that drain fluid from your inner ears, called the eustachian (yoo-STAY-shun) tubes.
Pseudoephedrine Hcl may also be used for purposes not listed in this medication guide.
