What is a common side effect of chronic use of inhaled corticosteroids like Beclomethasone?

Inhaled corticosteroids, such as Beclomethasone, are commonly used in the management of chronic respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). One of the well-documented side effects of these medications is oral thrush, also known as oropharyngeal candidiasis.

Oral thrush occurs due to the immunosuppressive effects of corticosteroids, even when inhaled. The localized application can disrupt the normal oral flora, allowing for the overgrowth of Candida species, leading to a fungal infection characterized by white patches in the mouth and throat. The risk of developing thrush increases if the medication is not used properly, particularly if patients do not perform good oral hygiene practices following inhaler use, such as rinsing their mouth after inhalation.

This side effect underscores the importance of patient education regarding the proper use of inhalers and the need for routine oral care to mitigate risks associated with inhaled corticosteroids.
