What Is a Vasoconstrictor?
Your eye doctor may suggest a vasoconstrictor eye drop for treating red eyes or eye allergies. Vasoconstrictor eye drops are available without a prescription, but are not recommended for long-term use. These drops can cause “rebound redness” in which the constricted blood vessels relax, dilate and cause even more redness than before.
