Employ Benzonak 5% Lotion in the exact dose and duration prescribed by your doctor or follow the instructions provided in the leaflet. Wash and dry the affected area before application. It may take several weeks for your symptoms to improve. Retain using it as advised. Consult your doctor if your condition does not improve after a month of regular use.

Ordinary side effects of Benzonak 5% Lotion include itching, stinging, peeling, and redness of the skin. They are not usually serious, but tell your doctor if they bother you or do not go away. You may need to apply a smaller amount or use it less often. It can also bleach hair and fabrics, including clothes, so be careful to avoid contact with these.
