An article about Tetryzoline, a medication used to relieve redness in the eyes.

Tetryzoline[edit]

Tetryzoline, also known as tetrahydrozoline, is a medication primarily used to relieve redness in the eyes caused by minor irritations. It is a vasoconstrictor, which means it works by narrowing the blood vessels in the eye, reducing redness and swelling.

Mechanism of Action[edit]

Tetryzoline is an imidazoline derivative that acts as an alpha-adrenergic receptor agonist. By stimulating these receptors, tetryzoline causes vasoconstriction of the blood vessels in the conjunctiva, leading to decreased blood flow and reduced redness.

Uses[edit]

Tetryzoline is commonly found in over-the-counter ophthalmic solutions used to relieve eye redness due to minor irritations such as exposure to wind, sun, or smoke. It is also used in some nasal decongestant sprays.

Side Effects[edit]

Common side effects of tetryzoline include:

Temporary stinging or burning of the eyes
Blurred vision
Increased redness or irritation of the eyes

In rare cases, systemic absorption can lead to more serious side effects such as:

Hypertension
Tachycardia
Headache

Precautions[edit]

Tetryzoline should be used with caution in individuals with:

It is important to follow the recommended dosage and not to use the product for more than 72 hours without consulting a healthcare professional.
