Introduction
Under normal circumstances,赛洛唑啉 hydrochloride nasal spray is used as a nasal decongestant. Its main effects include rapidly clearing nasal passages, reducing nasal mucosal congestion, improving nasal ventilation, relieving discomfort associated with nasal congestion, and assisting in nasal examinations. It should not be used continuously for more than 7 days to avoid drug dependence. Dosage must be strictly controlled according to the instructions or as directed by a physician.

Generally,赛洛唑啉 hydrochloride nasal spray is used as a nasal decongestant, with main effects including rapid relief of nasal obstruction, reduction of nasal mucosal congestion, improvement of nasal ventilation, alleviation of discomfort associated with nasal congestion, and assistance in nasal examinations. The details are as follows:

1. Rapid relief of nasal obstruction: The medication quickly constricts blood vessels in the nasal mucosa, making it suitable for sudden nasal congestion caused by acute rhinitis or allergic rhinitis. Nasal blockage can be relieved within minutes after spraying, restoring unobstructed airflow.

2. Reduction of nasal mucosal congestion: For nasal mucosal redness, swelling, and congestion caused by colds or rhinitis, the vasoconstrictive effect reduces local blood flow to the mucosa, thereby decreasing the degree of congestion and swelling and improving the condition of the nasal mucosa.

3. Improvement of nasal ventilation: As nasal mucosal swelling subsides, airway resistance decreases, effectively improving breathing difficulties caused by nasal congestion, especially relieving mouth breathing and sleep disruptions due to nighttime nasal blockage.

4. Alleviation of discomfort associated with nasal congestion: By improving airflow, the medication indirectly reduces accompanying symptoms such as headache, dizziness, and temporary loss of smell caused by nasal congestion, enhancing patient comfort during daily activities.

5. Assistance in nasal examinations: When used before nasal examinations or minor nasal procedures, it helps shrink the nasal mucosa and expand the nasal cavity view, allowing doctors to observe the internal nasal structures more clearly and improve diagnostic accuracy.

It is important to note that continuous use should not exceed 7 days to avoid drug dependence. Dosage must be strictly controlled according to the instructions or medical advice. Special populations such as patients with hypertension or glaucoma should use this medication with caution.
