Introduction

In general, there is no fixed standard for the frequency of nasal irrigation in rhinitis; it should be adjusted according to the type of rhinitis and severity of symptoms. Irrigation can be performed more frequently during acute rhinitis or when symptoms are pronounced, while the frequency should be reduced in chronic rhinitis or for daily care, guided by the principle of comfort and absence of irritation. Nasal irrigation devices should be regularly disinfected to prevent bacterial growth. After irrigation, nasal sprays may be used as needed to enhance the effect.

In general, there is no fixed standard for the frequency of nasal irrigation in cases of rhinitis. The frequency should be adjusted according to the type and severity of rhinitis. Irrigation can be performed more frequently during acute episodes or when symptoms are severe, while it should be reduced for chronic rhinitis or routine care, with comfort and absence of irritation as guiding principles. Specific details are as follows:

During acute rhinitis—such as nasal congestion and yellow discharge caused by a cold—or severe allergic rhinitis, when nasal secretions are abundant and mucosal congestion is present, irrigation can be done 3–4 times daily. Using saline solution helps quickly remove secretions and allergens, reduces mucosal irritation, and alleviates discomfort such as nasal congestion and sneezing.

For patients with chronic rhinitis or for routine nasal hygiene, frequent irrigation is unnecessary; once or twice daily is sufficient. Excessive irrigation may disrupt the normal nasal flora and mucosal barrier, leading to dryness and increased sensitivity. When irrigating, maintain proper posture by leaning forward to prevent fluid from entering the middle ear, and use water at a temperature close to body temperature to minimize irritation.

Nasal irrigation devices should be disinfected regularly to prevent bacterial growth. After irrigation, intranasal sprays may be used as needed to enhance therapeutic effects. It's also important to avoid exposure to allergens such as dust and pollen in daily life, and to maintain indoor air humidity to better support recovery from rhinitis.

Can loratadine syrup and ambroxol relieve cough and expel phlegm?

If cough is triggered by allergic factors (such as allergic rhinitis or allergic pharyngitis), loratadine syrup can relieve cough symptoms through its antiallergic effects, but it is ineffective against coughs caused by bacterial or viral infections or various conditions involving sputum production. If the cough and sputum are due to a common cold alone, using only these two medications is unlikely to comprehensively improve symptoms; treatment should be tailored according to the underlying cause with appropriate drugs.

If used for the prevention of asthma attacks or long-term control of allergic rhinitis, and the condition has remained stable for a prolonged period (e.g., several months without episodes), the dosing may be adjusted to every other day after comprehensive evaluation by a physician. This approach should only be undertaken when good disease control is ensured, and symptoms remain stable even with reduced dosing frequency, to avoid disease recurrence due to excessively prolonged dosing intervals.

What type of inflammation causes blood in nasal discharge?

Blood in nasal discharge may be caused by conditions such as atrophic rhinitis, allergic rhinitis, acute rhinitis, sinusitis with secondary rhinitis, or dry rhinitis. In dry rhinitis, the nasal mucosa remains chronically dry, leading to thinning of the mucosal surface and increased fragility, making it prone to cracking and bleeding. This is often accompanied by a sensation of nasal burning or the feeling of a foreign body. Symptoms are particularly noticeable during the dry seasons of autumn and winter or in individuals who spend prolonged periods in air-conditioned environments.
