Mite bites may cause mite dermatitis. It can be treated by general treatment, local medication and systemic medication. 1. General treatment: patients should first get out of the environment of mite bites, and should take baths, change clothes and beddings diligently. 2. Local medication: patients can apply anti-inflammatory and anti-itching drugs, such as glycerite lotion, to improve the symptoms of local itching. If necessary, glucocorticoid creams such as hydrocortisone and betamethasone can be applied to reduce inflammation and relieve itching. 3. Systemic medication: If the patient’s rash is more extensive and the inflammatory reaction is obvious, the patient can cooperate with the doctor to choose oral antihistamines, such as loratadine, cetirizine and so on, so as to improve the patient’s itchy skin symptoms. It is recommended that the patient in the diagnosis of mite dermatitis, need to cooperate with the doctor as soon as possible for standardized treatment, so as to reduce the patient’s symptoms.
