Applying warm, wet compresses is a home remedy suitable for treating boils on the skin, according to WebMD. This brings the boil to a head and causes it to burst. Once the boil drains, washing it several times a day, applying antibiotic ointment, and covering with a bandage prevents infection.
If the boil is large or it does not drain after application of wet compresses, a doctor may have to lance it to encourage drainage, advises MedicineNet. Larger boils sometimes include multiple pockets of pus that require drainage. If a bacterial infection is present, the doctor is likely to prescribe antibiotics, but not all boils require antibiotics.
