Pemphigus is typically an autoimmune disorder affecting the skin and mucous membranes, commonly seen in middle-aged and elderly individuals. When the body's immune system malfunctions, pathogenic pemphigus antibodies form in the bloodstream. These antibodies attack normal cells in the skin, leading to the development of large blisters on the skin and mucous membranes. The condition is usually non-contagious. In more severe cases, symptoms such as fever, loss of appetite, and general weakness may occur. If secondary infections develop, they may pose a threat to overall health.

Patients with pemphigus should follow their doctor’s guidance for treatment, which may include oral medications such as prednisolone acetate tablets or dexamethasone tablets, and topical applications like benzalkonium bromide solution. Proper skin care is essential—wear loose, comfortable clothing, preferably made of cotton. Maintain a light diet, ensure adequate intake of vitamins, and consume plenty of fresh fruits and vegetables to help relieve skin dryness and itching. Avoid scratching the affected areas and keep the skin clean.
