By Mayo Clinic staffDiaper rash is usually easily treated and improves within several days after starting home treatment.
If your baby's skin doesn't improve after a few days of home treatment with over-the-counter ointment and more frequent diaper changes, talk to your doctor. Sometimes, diaper rash leads to secondary infections that may require prescription medications. Have your child examined if the rash is severe, worsens despite home treatment or occurs along with any of the following:
- Fever
- Blisters or boils
- A rash that extends beyond the diaper area
- Pus or weeping discharge
