Symptomatic Lichen Planus
If biopsy-proven oral lichen planus becomes symptomatic, treat with:
Advise patients to stop using topical corticosteroids once symptoms have resolved. If the patient’s symptoms have not improved after 3 weeks of topical corticosteroids, the symptoms change or the appearance or texture of the lesion changes, advise patients to return to their treating specialist.
Betamethasone dipropionate 0.05% cream or ointment topically to the lesions, twice daily after meals, until symptoms resolve.
The treating specialist should perform the biopsy of an oral mucosal lesion.
In rural or remote areas where a delay in specialist review is expected, seek expert advice on biopsy technique. Doing a punch biopsy is not appropriate for Lichen Planus.
