==Composition==
==Visine==
Visine's active ingredient is [[tetrahydrozoline hydrochloride]], a [[vasoconstrictor]] that works by temporarily narrowing the blood vessels in the eye, thereby reducing redness and providing relief from discomfort. The concentration of tetrahydrozoline hydrochloride in Visine formulations can vary, but it typically ranges around 0.05%. Other ingredients in Visine products may include [[benzalkonium chloride]] as a preservative, [[boric acid]], [[sodium borate]], and [[sodium chloride]] to help adjust the solution's pH and osmolarity to match that of natural tears.

'''Visine''' is a brand of [[over-the-counter]] [[eye drops]] produced by [[Johnson & Johnson]]. It is commonly used to relieve [[redness]] and minor [[eye irritation]]. Visine contains the active ingredient [[tetrahydrozoline]], which is a [[vasoconstrictor]].


==Indications==
==Uses==
Visine is primarily indicated for the temporary relief of redness due to minor eye irritations, such as those caused by [[dust]], [[smoke]], [[chlorine]], and exposure to other irritants. It is also used to relieve dryness of the eye. However, it is important to note that Visine should not be used as a treatment for red eyes caused by infections, serious eye conditions, or exposure to chemicals, as these situations require medical attention.
Visine is primarily used to alleviate [[ocular redness]] caused by minor irritants such as [[dust]], [[smoke]], [[chlorine]], and [[allergens]]. It works by constricting the superficial blood vessels in the [[conjunctiva]], thereby reducing redness and swelling.


==Usage==
==Mechanism of Action==
The recommended usage for Visine is to instill 1 to 2 drops in the affected eye(s) up to four times daily. Users are advised not to touch the tip of the bottle to any surface, including the eye, to avoid contamination. It is also recommended not to use this product while wearing contact lenses.
The active ingredient in Visine, tetrahydrozoline, is an [[alpha-adrenergic receptor]] [[agonist]]. It acts on the alpha-adrenergic receptors in the blood vessels of the eye, causing them to constrict. This vasoconstriction reduces blood flow to the superficial vessels, leading to decreased redness and swelling.


==Precautions==
==Side Effects==
Visine should be used with caution. Prolonged use of Visine and other redness-relief eye drops can lead to a condition known as [[rebound hyperemia]], where the redness of the eye becomes worse over time. This condition occurs because the blood vessels in the eye become less responsive to the effects of the medication, leading to increased redness and discomfort.
While Visine is generally safe for short-term use, it can cause side effects such as:
* [[Dryness]] of the eyes
* [[Rebound hyperemia]] (increased redness after the drops wear off)
* [[Pupil dilation]]
* [[Blurred vision]]


Patients with certain medical conditions, such as [[glaucoma]], should consult a healthcare professional before using Visine, as the vasoconstrictive action of tetrahydrozoline may exacerbate these conditions.
Prolonged use can lead to [[tolerance]] and [[dependence]], where the eyes become reliant on the drops to maintain normal appearance.


==Side Effects==
==Precautions==
Common side effects of Visine include temporary stinging or burning of the eyes upon application. In rare cases, more severe reactions can occur, such as increased redness of the eyes, eye pain, vision changes, or persistent irritation. If any of these symptoms occur, use of the product should be discontinued, and a healthcare provider should be consulted.
Visine should not be used for more than 72 hours without consulting a healthcare professional. It is not recommended for individuals with [[glaucoma]], as it can increase [[intraocular pressure]].


==Conclusion==
==Alternatives==
Visine is a widely used over-the-counter product for the temporary relief of eye redness and discomfort. While it is effective for minor irritations, it is important for users to be aware of the potential for rebound hyperemia with prolonged use and to consult a healthcare professional if they have pre-existing eye conditions or experience severe side effects.
Other treatments for eye redness and irritation include:
* [[Artificial tears]]
* [[Cold compresses]]
* [[Antihistamine]] eye drops for allergy-related redness
