Naproxen is a nonsteroidal anti-inflammatory drug (NSAID). Naproxen works by reducing hormones that cause inflammation and pain in the body.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
Naproxen and pseudoephedrine is a combination medicine used to treat stuffy nose, sinus congestion, headache, fever, and minor aches and pains caused by the common cold or flu.
