If purely on the way of disease treatment in terms of methods, nebulization and medication are very safe, these two ways are not particularly harmful, but there are two points: First, the nebulization of drugs directly on the respiratory system, the effect is better. However, it depends on the individual’s tolerance level, some people’s airways are in a highly sensitive, some nebulized drugs have a taste, so the patient or the user’s subjective feeling is not good, and some of them can also lead to tracheal spasm, asthma and cough aggravation, these patients are not suitable for nebulization. Secondly, oral medication due to gastrointestinal absorption, easy to cause gastrointestinal adverse reactions when consumed on an empty stomach, such as nausea, vomiting, in addition, oral medication relative to nebulization on the systemic side effects will be more, such as liver function abnormalities, renal function effects, and so on. Therefore, we should be clear about why nebulization and medication should have different treatment modalities, as well as the treatment modalities that patients are accustomed to be able to accept, and at the same time, the most crucial thing to consider is that there are sufficient reasons for the doctor to prescribe this type of treatment, with full consideration given to the therapeutic ideas and strategies that can lead to early recovery in a safe, fast, and effective manner.
