Hydrocortisone butyrate cream is a hormonal cream, which is a glucocorticoid-based topical medication, and is mainly effective for eczema, papular urticaria, and allergic dermatitis caused by allergies. However, because it is a glucocorticoid, it cannot be used for a long time on a large area. If it is used for a long time on a large area, it may cause certain side effects. The main side effects are local capillary dilation, secondary bacterial and fungal infections, and possibly hormone dependency reactions. But it is okay to use it for a short time.
