What are the treatment options for lichen planus?

Lichen planus is an inflammatory condition that may cause itchy purple or reddish bumps, flat patches, mouth soreness, scalp changes, nail changes, or genital discomfort. Topical corticosteroids are applied directly to affected skin or lining tissue to reduce inflammation and itch. The strength, vehicle, and duration need to match the body site because thin or sensitive areas require different care from thicker skin. Oral corticosteroid treatment works throughout the body and may be considered when symptoms are widespread, severe, or difficult to control with local treatment. A clinician may also need to assess mouth, scalp, nails, or genital symptoms separately.

Arrange a medical assessment if a new persistent rash, mouth lesion, or genital symptom could be lichen planus. Use prescribed topical treatment in the amount and schedule advised, and avoid applying a strong steroid to the face, folds, or genital skin without specific instructions. Gentle fragrance-free skin care, avoiding scratching, and identifying irritating dental or cosmetic products can reduce aggravation. If oral treatment is prescribed, follow the tapering plan and report new symptoms rather than changing the dose yourself.

Seek prompt review for painful mouth ulcers, difficulty eating or swallowing, rapidly spreading rash, blistering, eye symptoms, scalp tenderness with hair loss, or genital sores. Contact the clinician if treatment causes worsening pain, skin thinning, unusual bruising, or signs of infection. Urgent help is needed for facial swelling, breathing difficulty, or sudden vision changes.

Ask which body areas are involved, how long to use topical corticosteroids, whether oral treatment is appropriate, which symptoms need specialist review, and how follow-up will check the mouth, nails, scalp, or genital skin.
