Why is Pseudoephedrine prescribed?
Pseudoephedrine is used to relieve nasal discomfort caused by colds, allergies, and hay fever. It is also used to relieve sinus congestion and pressure. Pseudoephedrine is in a class of medications called sympathomimetic agents that are used as nasal decongestants. It works by causing narrowing of the blood vessels of swollen nasal mucous membranes to reduce nasal congestion and allow drainage of sinus passages.
