Is the damage to the throat from nebulization permanent and incurable?

Generally speaking, there is no such thing as permanent, irreversible damage to the throat caused by nebulization. Although nebulization may sometimes cause throat irritation, any resulting injury is usually temporary and gradually resolves over time. Specific details are as follows:

Nebulization is a treatment method that converts liquid medication into a mist, allowing it to directly reach the respiratory tract and lungs. When used appropriately under medical supervision, nebulization is a safe and effective treatment for respiratory diseases. However, improper or excessive use of nebulization may cause harm to the throat and airways. This is because certain medications—such as ambroxol hydrochloride solution for inhalation or levosalbutamol hydrochloride nebulizer solution—may irritate the throat and respiratory tract. Prolonged or excessive use of these drugs may lead to throat damage. Additionally, the nebulizer device itself can become a breeding ground for bacteria or fungi. If not cleaned and disinfected regularly, it may cause infections that damage the throat and respiratory system. Fortunately, such injuries are typically temporary and tend to resolve gradually after stopping nebulization, so there is generally no need for excessive concern.

It is important to strictly follow a doctor's instructions when using a nebulizer, avoid misuse or overuse, and clean and disinfect the device regularly to minimize potential harm to the throat and respiratory tract.
