Occlusive dressings for lichen simplex chronicus should be left on for no more than how many hours?

• A. 2-4 hours
• B. 12-24 hours
• C. 6-8 hours
• D. 48 hours

Answer: (C)

Occlusion helps deliver more of the topical steroid into the thick, leathery plaques of lichen simplex chronicus, speeding relief of itch and inflammation and helping to break the itch-scratch cycle. But keeping a dressing on increases skin absorption and the risk of side effects, including thinning of the skin, satellite skin changes, and even systemic effects if absorbed over time. That’s why the duration is kept short: about six to eight hours. This window provides enough time for the medication to work on the plaques while minimizing excessive absorption and local or systemic complications. Leaving a dressing on much longer raises the risk of maceration, infection, and adverse effects, while shorter periods may not achieve sufficient therapeutic benefit.
