Naphazoline is a medication that belongs to the class of drugs known as alpha-adrenergic agonists. It is commonly used as a decongestant, particularly in ophthalmic (eye) formulations. Naphazoline works by constricting the blood vessels in the eyes, leading to a reduction in redness and swelling. This makes it effective in relieving eye irritation and discomfort caused by conditions such as allergies, minor eye irritation, or exposure to environmental irritants.
