The treatment methods for pemphigus foliaceus are the same as those for other types of pemphigus. Currently, glucocorticoids remain the first - choice drugs for treating pemphigus. They should be applied as early as possible, with standardized treatment and long - term maintenance. Generally, the initial dose starts with 60 - 100 milligrams of prednisone per day. For patients with severe conditions, the pulse therapy can be used. When using glucocorticoids, attention should be paid to their adverse reactions, such as imbalance of water and electrolytes, elevated blood sugar and blood pressure, osteoporosis, etc. At the same time, prevention and treatment of these side effects of glucocorticoids are necessary. In cases where the treatment effect is not satisfactory, human immunoglobulin pulse therapy or combination therapy with immunosuppressants can be used. Usually, glucocorticoids should be used first to control the condition, and then immunosuppressants can be added. Commonly used immunosuppressants include azathioprine, cyclophosphamide, cyclosporine, etc. Dapsone is also a commonly used treatment drug, which is often used to treat pemphigus erythematosus or pemphigus foliaceus. Other treatment methods include plasma exchange therapy and blood plasma transfusion.
