If eczema becomes infected, the first thing you can do is apply antibiotic ointment topically, commonly used ointments are erythromycin ointment, mupirocin ointment, fusidic acid ointment. If there is significant exudation at the same time, you can also apply some solutions for wet compresses, such as diluted potassium permanganate solution, ezacridine lactate solution, boric acid solution, can be applied. When the exudation is less and the bacterial infection is under control, topical application of glycopyrrolate lotion and glucocorticoid ointment can be used to treat eczema. The patient will also have a pronounced itching sensation, for which the patient can take oral antihistamines to relieve, such as loratadine, cetirizine, paracetamol, and epalmatine tablets, all of which are commonly used and have good effects.
