What causes an itchy nose?

Generally, an itchy nose may be caused by dry air, unhealthy habits, medication effects, allergic rhinitis, sinusitis, or other reasons. Patients should promptly visit a正规 hospital to identify the underlying cause and receive targeted treatment. Specific causes are as follows:

1. Dry Air

Dry environments can make nasal mucosa fragile and prone to itching. Additionally, dry air may reduce nasal secretions, further aggravating the sensation of itchiness. It is recommended to stay hydrated and get adequate rest to help relieve symptoms.

2. Unhealthy Habits

Frequent nose picking, aggressive nasal cleaning, or forceful nose blowing can irritate the nasal mucosa and lead to the aforementioned issues. It is advised to correct these unhealthy habits and avoid routinely picking the nostrils.

3. Medication Effects

The use of certain hormonal medications in the nasal area may irritate or dry out the nasal mucosa, causing itching. Patients should consult their doctor to reduce or discontinue such medications as appropriate.

4. Allergic Rhinitis

Common allergens include pollen, dust mites, animal dander, etc. When allergens enter the nasal cavity, the immune system releases histamine, leading to symptoms such as nasal itching, runny nose, and sneezing. Under medical guidance, patients may take medications such as loratadine tablets, cetirizine hydrochloride tablets, or ebastine tablets. It is also important to avoid contact with known allergens in daily life.

5. Sinusitis

Sinusitis refers to infection or inflammation of the sinuses, which can cause congestion and swelling of the nasal mucosa, making it more sensitive to itching. In addition, inflammation may stimulate nerve endings, intensifying the itch. Patients are advised to take medications such as Biyuan Tongqiao Granules, Cefixime Capsules, or Tongqiao Biyan Tablets under medical supervision.

Patients experiencing an itchy nose should promptly visit an otorhinolaryngology (ENT) department for evaluation, including examinations such as nasal endoscopy, to establish a clear diagnosis. During treatment, it is important to drink plenty of water and avoid picking the nose to prevent damage to the nasal mucosa.
