Medicines for Oral lichen planus

What it is

Oral lichen planus is a common, long-term inflammatory condition affecting the lining of the mouth, thought to be caused by the immune system. It can appear in different ways: most commonly as lacy white patches or streaks (often on the inner cheeks), but also as red, sore or inflamed areas, or, less commonly, ulcers. Mild cases with just white patches often cause no symptoms and are found by chance, while more inflamed or ulcerated forms can cause soreness, burning, and discomfort with certain foods (especially spicy, acidic or crunchy ones). It can also affect the gums and tongue, and lichen planus can sometimes affect the skin and other areas too. It is not contagious. It tends to be a persistent condition that comes and goes over time. Because there is a small increased risk of changes in the affected areas over the long term, people with oral lichen planus are usually monitored.

How it is treated

Management depends on the symptoms. Mild, symptom-free oral lichen planus (just white patches) usually needs no active treatment beyond good oral hygiene and monitoring. For sore or inflamed forms, treatment aims to reduce the inflammation and relieve discomfort — commonly with topical steroid treatments applied to the mouth, along with soothing measures, avoiding trigger foods, and gentle oral care; more resistant cases may need other treatments under specialist care. Identifying and, where possible, removing any contributing factors — such as certain medicines, rough dental work, or reactions to dental materials in some people — can help. Because of the small long-term risk of change in the affected areas, regular review (often with a dentist or oral medicine specialist) is advised, and any new lump, ulcer that does not heal, or changing patch is checked. The reassuring message is that oral lichen planus is usually manageable, and while it is a long-term condition, monitoring keeps it safe.
