Introduction
Dry cough caused by disinfectants can generally be relieved with medications such as dextromethorphan, pentoxyverine, ambroxol, loratadine, or montelukast. Dextromethorphan suppresses the cough center and alleviates dry cough symptoms. It is suitable for non-productive (dry) cough induced by irritation from disinfectants, offering a mild effect with rapid onset. It helps reduce frequent coughing due to irritated throat mucosa without affecting daily activities or sleep.

Dry cough caused by disinfectants can generally be relieved with medications such as dextromethorphan, pentopirilin, ambroxol, loratadine, or montelukast. Specific analysis is as follows:

1. Dextromethorphan: A centrally acting antitussive that suppresses the cough center and alleviates dry cough symptoms. It is suitable for non-productive dry cough induced by disinfectant irritation, with a mild effect and rapid onset. It reduces frequent coughing due to irritated pharyngeal mucosa without affecting daily activities or sleep.

2. Pentopirilin: Exerts both central and peripheral antitussive effects, providing stable cough suppression. It effectively relieves dry cough caused by hypersensitive respiratory mucosa and improves throat itching and irritative cough resulting from disinfectant exposure. With minimal side effects, it is suitable for short-term use in most individuals.

3. Ambroxol: Although primarily a mucolytic agent, it moistens the respiratory mucosa and reduces the impact of irritants on the throat. For dry cough accompanied by throat dryness and discomfort, it helps alleviate cough reflexes triggered by mucosal dryness and promotes repair of the respiratory mucosa, thereby assisting in symptom relief.

4. Loratadine: An antihistamine that reduces allergic reactions in the respiratory mucosa. If disinfectant components trigger an allergic response leading to dry cough, loratadine can inhibit the release of allergic mediators, relieving throat itching and dry cough. It is less likely to cause drowsiness and is therefore suitable for daytime use.

5. Montelukast: A leukotriene receptor antagonist that reduces airway inflammatory responses. It is indicated for dry cough with airway hyperresponsiveness caused by disinfectant irritation. By decreasing airway sensitivity, it reduces the frequency of coughing episodes and is especially appropriate for prolonged dry cough.

Before using any medication, ensure there is no history of drug allergy. Always follow the instructions on the label or those provided by a healthcare professional, and avoid adjusting the dosage independently. If dry cough persists for more than one week or is accompanied by sore throat or chest tightness, seek medical evaluation promptly.

What are the benefits and drawbacks of drinking pear juice in autumn?
The benefits of drinking pear-infused water in autumn generally include nourishing yin, moistening the lungs, promoting saliva production to quench thirst, alleviating autumn dryness, replenishing nutrients, and soothing the throat. Potential drawbacks may include gastrointestinal irritation due to its cooling nature, increasing internal dampness, and impairing digestive function. Pears are naturally cool in nature and sweet in taste; when boiled in water, they retain their lung-moistening properties. As the air tends to be dry in autumn, consuming pear water can nourish lung yin, relieve discomforts such as dry cough and minimal phlegm caused by lung dryness, and support overall lung health.

What does it feel like to have a tumor in the lung?
When there is a tumor in the lung, symptoms generally include persistent cough, blood in sputum or hemoptysis, chest pain, chest tightness, shortness of breath, and unexplained weight loss. The tumor irritates the respiratory mucosa, causing a chronic cough, often characterized as an irritating dry cough, sometimes accompanied by small amounts of sputum. This cough is difficult to relieve with common antitussive medications, and its frequency gradually increases as the disease progresses.

Is it serious if an elderly person with dry cough and phlegm is advised by a doctor to undergo a biopsy?
The biopsy examination is mostly used to rule out lung infections, nodules, inflammation, and other issues. In elderly individuals, a persistent dry cough with phlegm may be caused by benign conditions such as chronic bronchitis or pneumonia. These cases generally have a good prognosis with targeted treatment, so there is no need for excessive concern. If the examination reveals abnormal lesions, such as tumors, further intervention and treatment will be required.

Can procaterol be taken together with dextromethorphan?
If coughing is accompanied by noticeable wheezing and airway spasms, with little or no sputum, and a doctor diagnoses conditions such as bronchial asthma or asthmatic bronchitis, these two medications may be taken together under medical guidance. Procaterol relaxes the bronchi and relieves wheezing, while dextromethorphan suppresses the cough center and reduces dry cough symptoms. Together, they provide more comprehensive relief from respiratory discomfort and help restore smooth breathing.
