What is a common side effect of using inhaled corticosteroids for asthma?

Inhaled corticosteroids are commonly prescribed for the management of asthma due to their potent anti-inflammatory effects, which help control symptoms and reduce the frequency of exacerbations. One of the notable side effects associated with the use of inhaled corticosteroids is oral thrush, a fungal infection caused by Candida species. This occurs because inhaled corticosteroids can disrupt the normal balance of microorganisms in the mouth and throat, creating an environment conducive to fungal growth.

Patients using inhaled corticosteroids may not realize the need for proper inhaler technique, which includes the importance of rinsing the mouth and throat after use. This practice helps minimize the risk of developing oral thrush by flushing out residual medication and preventing the overgrowth of fungi. Therefore, recognizing oral thrush as a potential side effect is crucial for patients and healthcare providers to ensure appropriate management and maintain oral health while effectively controlling asthma symptoms.
