A nebuliser is a drug delivery device that converts the liquid into mist to inhale medications through the airway, especially for the treatment of various respiratory diseases like asthma, chronic obstructive pulmonary disease, cystic fibrosis, etc.

Nebulisers can be used to deliver bronchodilators for treating asthma like albuterol for quick relief, ipratropium to relieve asthma flares, budesonide to reduce airway inflammation, cromolyn sodium to reduce airway inflammation, etc. A combination of drugs can also be given like inhalers for long-term control. Other medications like antibiotics and sterile saline solution can also be provided.

In case of cold and cough one does not require using a nebuliser. They can generally treat it by giving steam inhalations, decongestant nasal drops for nasal blockage or increased cough. For patients suffering from a respiratory illness like asthma who spit cough or suffer from cough problems nebulisers are used.

People belonging to any age group from toddlers, infants to olds who may be suffering from cough, airway inflammation, asthma flares, etc. or diseases like viral bronchiolitis, respiratory syncytial virus (RSV), which is very common in infants, asthma, bronchiectasis, cystic fibrosis, COPD, etc.

It is used to deliver the drug directly into the respiratory tract for immediate effect, being easier to use than metered-dose inhaler (MDI), especially for children who are not old enough to know how to use MDI. In an emergency, they can get quick response by opening up the airway to treat infections like asthma, COPD, bronchiolitis, and RSV to relieve dyspnoea in alveolar carcinoma patients.
