There are two types of dermatoprost, one with dexamethasone acetate as the main ingredient and one with mometasone as the main ingredient. As topical glucocorticosteroids are the first line of treatment for cutaneous lupus erythematosus, often the doctor has already prescribed glucocorticosteroids for the patient. Combined application of similar drugs is generally a major contraindication to medication, which does not improve efficacy but increases adverse reactions. Therefore, it is recommended to strictly follow medical advice and not to add or subtract drugs privately.
