Euthyroxine, also known as hydrocortisone butyrate cream, is a topical glucocorticoid drug. Generally speaking, its side effects are not too obvious, but long-term use is not recommended. Long-term use may lead to skin atrophy, capillary dilation, hyperpigmentation and secondary infection, which are the side effects that are more likely to occur with long-term use of glucocorticoid topical drugs, so patients are not recommended to use it for a long time. Consult your doctor. In addition, Eudragit Ointment should not be used on broken skin, and contact with eyes and other mucous membranes, such as the oral and nasal mucous membranes, should be avoided during use. In conclusion, Eudragit ointment is a topical glucocorticoid drug with anti-inflammatory, anti-allergic, anti-itching and exudation reducing effects, but it is not recommended for long-term use, as long-term use can easily lead to glucocorticoid skin side effects.
