All of them can have certain effect on getting rid of lichen planus. 2. Topical drugs: such as acrylamide antifungal drugs, common acrylamide antifungal drugs are terbinafine, bupropion and so on. The application of acrylamide drugs are less likely to have adverse reactions, but occasionally see rashes, itching, arthralgia and muscle pain, etc., is a normal reaction. You can also use azole drugs, such as ketoconazole, fluconazole and so on. 3.
