Treatment for lichen planus is:

Correct answer: D. Corticosteroids

• A. Antivirals are not used for lichen planus — lichen planus is not caused by a virus (unlike herpes labialis).
• B. Antibiotics have no role in the treatment of lichen planus, which is a T-cell mediated autoimmune condition.
• C. Antifungals (fluconazole) are NOT first-line for lichen planus. However, they may be added if candidal superinfection develops (common in immunosuppressed patients on corticosteroids).
• D. Corticosteroids (topical, intralesional, or systemic) are the FIRST-LINE treatment for symptomatic oral lichen planus. Topical corticosteroids (fluocinonide, clobetasol, dexamethasone rinses) are preferred. Systemic corticosteroids are reserved for severe/widespread disease. There is no cure; treatment reduces inflammation and symptoms.
