Denide is a class of glucocorticosteroids, which are generally recommended for a maximum of 2 weeks. It is mainly used for skin allergy, contact dermatitis, neurodermatitis, seborrheic dermatitis and other skin diseases, and has good therapeutic effect. However, since this drug is a hormonal drug, it can be used for 2 weeks at most. After long-term application, the skin may have adverse reactions, such as folliculitis, hirsutism, acne-like rash, secondary infection and skin atrophy. If the treatment is not effective after 2 weeks of use, it is recommended to visit a hospital dermatologist and change to another medication under the guidance of a medical professional. Although Denide has a good therapeutic effect on many types of dermatitis, it has no therapeutic effect on diseases such as infection or acne, and some patients may experience local burning, itching, and increased hairiness after using it. Therefore, you must choose to use the medication under the guidance of a professional doctor, and do not use it blindly on your own to avoid delaying the disease.
