Euthyroxine ointment is hydrocortisone butyrate ointment, which is a weak glucocorticoid ointment and is mainly used in dermatology for the treatment of allergic diseases, such as dermatitis, eczema and pruritus. Topical glucocorticosteroids have certain side effects, which can cause local capillary dilation, skin atrophy, purpura, hirsutism, folliculitis or pigmentation, and also increase the chance of infection by pathogenic microorganisms. Therefore, the skin in areas like face, breast, underarm and genitalia is relatively thin and has a strong absorption capacity for hormones, so attention should be paid to the intensity and application length when applying. Therefore, dermatologists usually do not recommend the use of Eudragit Ointment on the facial area, and the side effects of hormones may occur after prolonged application.
