Patients with chickenpox who have itching are treated with topical medications to stop the itching and oral medications, which have not been reported. This is because most of the oral anti-itch medications are antihistamines, that is, for allergies that cause itching. The itching caused by chickenpox has nothing to do with allergy and histamine, so it is not considered to apply antihistamine drugs to stop itching in patients with chickenpox, nor is it thought to have the appropriate effect, nor has it been used in this way in clinical practice. For patients with chicken pox itching, topical medications are mainly used to control the symptoms. The most common drug used externally is furnace glycerine lotion, which is used topically, and also has a certain effect of collecting moisture. In addition, you can also use Chinese medicine, such as mangosteen, bitter ginseng, floating pine decoction for external washing, or direct application of proprietary Chinese medicine, the clinical use of compound cypress liquid coating, also has a certain effect.
