What to expect from oral corticosteroid treatment for lichen planus

Lichen planus can affect skin, the mouth, genitals, nails, or scalp. Oral corticosteroids reduce inflammatory activity throughout the body, so they may be considered when symptoms are extensive, severe, or affecting sensitive areas. The response depends on which sites are involved and how active the condition is.

Itching, new bumps, soreness, or mouth irritation may ease before older marks or colour changes fade. Treatment does not remove the need to assess persistent mouth or genital symptoms. Your clinician may combine oral medicine with local care for particular areas.

Take each dose according to the prescription and follow the reduction schedule provided; stopping suddenly can be unsafe after ongoing treatment. Taking the medicine with food may reduce stomach irritation. Keep a record of new symptoms, sleep or mood changes, and any change in mouth, genital, nail, or scalp involvement.

Share your history of diabetes, high blood pressure, ulcers, bone disease, eye problems, infections, and mental health symptoms. Tell the clinician about vaccines, medicines, and supplements. Gentle skin care and avoiding scratching can reduce irritation, while mouth or genital pain may need area-specific advice.

Contact your clinician if the rash spreads, mouth or genital soreness makes eating or urinating difficult, or symptoms return during dose reduction. Seek urgent help for trouble breathing or swallowing, facial swelling, severe eye pain or vision change, confusion, black stools, or rapidly worsening illness with fever.

Ask which areas of lichen planus the medicine is intended to treat, how improvement will be checked, how the taper will work, and whether local treatment is needed for the mouth, genitals, nails, or scalp. Ask which warning symptoms should bypass a routine appointment.
