Neozoline nasal and eye drops are used to relieve congestion and redness in the nose and eyes. They work by constricting the blood vessels in the mucous membranes of the nose and eyes, which reduces swelling and redness, helps improve breathing, and relieves congestion and irritation. They are used for colds, flu, sinusitis, and minor eye irritations such as redness caused by allergies or stress. They also help relieve temporary fatigue and inflammation.
Neozoline should only be used for short periods to avoid dependence or chronic irritation. It is not recommended to use it for long periods without consulting a doctor to avoid side effects such as dryness of the nose or eyes or worsening of the condition.
