Atrovin S Nasal Drops are used for managing nasal congestion. It promotes easier breathing by moisturising the nasal passages. It helps loosen thick mucus and clear blocked airways caused by colds or allergies. Maintaining the moisture balance inside the nose supports smoother airflow and overall nasal comfort. This formulation contains purified Sodium Chloride solution, known for its gentle hydrating and cleansing properties. It works by keeping the nasal mucosa moist and reducing dryness or irritation that can occur from pollution, low humidity, or cold weather.
