A patient has mucositis. All of the following are helpful for managing the situation EXCEPT:

Bland rinses, certain antimicrobial mouthwashes, and topical viscous lidocaine (for pain control) are all standard supportive measures for managing oral mucositis (e.g., from chemotherapy/radiation or other causes). Topical corticosteroids are not a standard part of general mucositis management — and in immunocompromised patients especially, they could theoretically increase infection risk in already-compromised mucosa, making this the exception.
