Pseudoephedrine is a medicine that reduces swelling in the blood vessels of the nasal passages. Swollen blood vessels can lead to nasal congestion (a stuffy nose).

Robitussin Cold and Cough is a combination medicine used to relieve cough, stuffy nose, sinus congestion, and chest congestion caused by allergies, the common cold, or the flu.
