Aspirin is in a group of drugs called salicylates (sa-LIS-il-ates). It works by reducing
substances in the body that cause pain, fever, and inflammation.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages.
Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of aspirin and pseudoephedrine is used to treat stuffy nose, sinus
congestion, and pain or fever caused by the common cold or flu.
Aspirin and pseudoephedrine may also be used for purposes other than those listed in this
medication guide.
