Visine
Visine® is a brand of eye drops produced by Pfizer Inc. PAUL DO SOME WORK!!!!
==Visine® Original== YOU TOO ELLIS!!!!!!!!!!
The active ingredient in the original Visine® formulation is tetrahydrozoline hydrochloride which is a vasoconstrictor, and therefore constricts the eye's superficial blood vessels to "get the red out", as claimed in Pfizer's advertising[1].
Administration
As with other eye drops, Visine® is administered topically with 1 to 2 drops applied to the affected eye(s) up to 4 times daily [citation needed].
Adverse effects
- Reducing the blood supply to the eye can prevent, or at least prolong, the healing cycle. Thus, the use of Visine® and other similar products is not helpful in healing the eyes [citation needed].
- Use will create a rebound after a couple of hours and make the eye look even redder. Prolonged use can permanently dilate blood vessels, so use should be limited to 1 or 2 times.
- Those using Visine® Original frequently report stinging and burning upon application[1].
- Although the use of Visine® as a poison to induce diarrhea has been discounted as an urban legend[2], systemic complications have been reported as a result of poisoning and accidental ingestion[2][3][4].
