Should I use mupirocin ointment when my baby’s eczema stops oozing?

The use of mupirocin ointment for baby eczema is not based on oozing or not, but on whether it is co-infected or not.
Mupirocin ointment is mainly used for skin diseases with Gram-positive cocci infections, such as eczema co-infections, impetigo, boils, folliculitis, and ulcer co-infections. It is a topical antibiotic. Adverse reactions to this product include local irritation, rash, and swelling. It is contraindicated in people who are allergic to the drug.
Eczema can be manifested as pemphigus, tendency to ooze, chronic stage can be manifested as mossy changes, etc., and is prone to recurring episodes. Therefore, eczema oozing is not necessarily a sign of co-infection, and you can not choose whether to use mupirocin ointment based on oozing.
If you suspect that there is secondary infection, you can improve the bacterial culture and drug sensitivity test, and choose sensitive antibiotic treatment. Mupirocin ointment can be used for eczema co-infections caused by sensitive bacteria. It should be used under the guidance of a doctor.
