Introduction

If patients fail to take their condition seriously, discontinue medication without authorization, or are exposed to strong irritants leading to severe acute attacks, it may result in serious airway spasms, difficulty breathing, and even complications such as respiratory failure. Without prompt emergency treatment, this condition could be life-threatening. The risk is particularly elevated among elderly patients or those with underlying medical conditions.

Under normal circumstances, cough-variant asthma does not lead to death when properly and consistently managed. However, there may be risks if treatment is delayed or acute attacks become uncontrolled. If in doubt, it is recommended to seek medical advice early. Detailed analysis is as follows:

If patients with cough-variant asthma follow medical advice for long-term, standardized treatment, avoid allergens and triggering factors, and maintain stable conditions without frequent acute exacerbations, the disease typically does not pose a life-threatening risk. These patients mainly experience chronic cough, with relatively mild airway spasms that can be effectively controlled using medication, resulting in minimal impact on overall respiratory function.

If patients neglect their condition, discontinue medication without guidance, or are exposed to strong irritants leading to severe acute attacks, they may develop serious airway spasms, difficulty breathing, and even complications such as respiratory failure. In such cases, failure to receive timely emergency treatment may endanger life. The risks are particularly higher among elderly patients or those with underlying health conditions.

Patients with cough-variant asthma should adhere to long-term medication use, undergo regular follow-ups to adjust treatment plans, clearly identify and avoid allergens and triggers, and immediately use rescue medications and seek medical care when experiencing worsening cough, chest tightness, or shortness of breath.

Can cefuroxime axetil tablets relieve cough and expel phlegm?

In general, cefuroxime axetil tablets cannot directly relieve cough or expel phlegm; they are only effective for treating respiratory inflammation caused by bacterial infections. To alleviate cough and sputum in daily life, measures such as drinking plenty of warm water, eating a light diet, and maintaining indoor humidity can be helpful.
