Clinicians often say “hormone” means “adrenocorticotropic hormone”, while other hormones are really called by their names, commonly used are oral and intramuscular, intravenous cortisone, prednisone, dexamethasone, etc., and topical ones are skin relaxation, de-inflammatory pine, dacrynic acid, etc. The textbook says that hormones have four major effects: anti-inflammatory, anti-toxic, anti-shock, and anti-allergic. The mechanism of action is very complex, simply put, except for anti-allergy, other effects must have reliable drug therapy to support, rely on hormones alone, the results are very bad, hormones are mainly to moderate and regulate the systemic response to the disease to produce harmful immune substances, rather than the direct role of the primary disease germs and viruses. In autoimmune diseases (which can also be called autoallergic) such as glomerulonephritis, lupus erythematosus, and hematological diseases, we have to rely on long-term use of hormones. The negative effects of long-term use are very serious sodium and water retention, endocrine metabolic disorders, and low body resistance. Except for acute sudden allergic diseases, such as poisonous insect stings or misuse of highly allergenic food, sudden generalized redness and swelling with respiratory difficulties, you can take 4 tablets of dexamethasone at once. Usually, you should not use them at your own discretion.
