Antibiotics taken by mouth usually clear up impetigo in four or five days. It's important for the antibiotic to be taken faithfully until the prescribed supply is completely used up.
An antibiotic ointment, such as Polysporin, should be applied thinly four times daily. Polysporin can be purchased without a prescription.
Crusts should be removed before the ointment is applied. Soak a soft, clean cloth in a mixture of one-half cup of white vinegar and a quart of lukewarm water. Press this cloth on the crusts for 10-15 minutes three or four times daily. Then gently wipe off the crusts and apply a little antibiotic ointment.
You can stop soaking the impetigo when crusts no longer form. When the skin is healed, stop the antibiotic ointment.
