Tetrahydrozoline

Introduction

Tetrahydrozoline is a commonly used medicine known for providing fast relief from eye redness, irritation, and nasal congestion. It belongs to a class of medicines called sympathomimetic agents and is mainly available in the form of eye drops or nasal drops. Tetrahydrozoline works by narrowing the small blood vessels in the affected area, which helps reduce redness, swelling, and discomfort. It is often recommended for temporary relief from symptoms caused by allergies, dust, smoke, pollution, or minor eye irritations. Due to its quick action and ease of use, it is widely used in both adults and children under medical guidance.

Uses of Tetrahydrozoline

• Relief from eye redness caused by irritation, dust, or smoke
• Temporary relief from allergic conjunctivitis
• Reduction of eye discomfort due to pollution or chlorine
• Relief from nasal congestion in common cold or allergies
• Soothing mild eye irritation and burning sensation

How Tetrahydrozoline Works

Tetrahydrozoline works by stimulating alpha-adrenergic receptors present in the blood vessels of the eyes or nasal lining. This action causes the blood vessels to constrict, which reduces blood flow to the area. As a result, redness, swelling, and irritation decrease quickly. Its effect starts within minutes, providing fast and noticeable relief from symptoms. However, it is meant for short-term use only and should not be used continuously for long periods without medical advice.
