Inhaled budesonide is mainly used in the treatment of bronchial asthma, replacing or reducing treatment with oral steroids. It is a glucocorticoid and can cause a variety of side effects such as respiratory infections, rhinitis, cough, otitis media, and oral candidiasis. However, because there are differences in body types between people, whether and how side effects occur varies from person to person. It is contraindicated in people with known allergies to this product. This product requires long-term persistent use, and side effects are inevitable during the use of the drug. It is recommended to closely observe your own condition during the use of the medication, and seek medical advice if you have any obvious discomfort, rather than stopping the medication on your own.
