Why is it important for patients to rinse their mouths after using corticosteroids?

Rinsing the mouth after using corticosteroids is crucial primarily to avoid irritation and infection in the mouth. Corticosteroids can suppress local immune responses in the oral cavity, making it easier for fungal infections, such as oral thrush, to develop. By rinsing the mouth, patients help to remove any residual medication that could contribute to irritation or provide an environment conducive to the growth of pathogens. This simple practice plays an important role in maintaining oral hygiene and preventing complications associated with corticosteroid use.
