What is a common side effect of long-term use of inhaled corticosteroids?

Long-term use of inhaled corticosteroids is commonly associated with oral thrush, also known as oropharyngeal candidiasis. This condition is caused by an overgrowth of the Candida fungus, which can occur when corticosteroids, even in inhaled form, disrupt the balance of microorganisms in the mouth. Inhalation of these medications can leave residual particles in the oral cavity, providing an environment that can foster fungal growth if proper oral hygiene is not maintained.

Patients using inhaled corticosteroids are therefore advised to rinse their mouths with water after each use and to practice good dental hygiene to minimize this risk. This preventive measure can help keep the mouth free from excess fungus, thus reducing the likelihood of developing oral thrush. It's essential for asthma educators to inform patients about this possible side effect and the importance of oral care, highlighting how it can prevent complications associated with inhaled corticosteroid therapy.
