A client who uses over-the-counter phenylephrine
(Neo-Synephrine) nasal spray asks the nurse how the medication works. The
nurses response would be:
1. It helps to shrink the swelling in your nose by
tightening the blood vessels there. 2. It works to locally destroy invading
organisms that cause colds and flu. 3. It coats the nasal passages to reduce
swelling. 4. It is absorbed after you swallow it to act as a decongestant.
