What should I do if a boil ruptures?

A furuncle (boil) is an acute suppurative infection affecting a single hair follicle and its surrounding tissue, commonly caused by pathogenic bacteria such as *Staphylococcus aureus*. It frequently occurs on exposed or friction-prone areas of the skin, including the face, neck, back, buttocks, and axillae. So, what should you do if a furuncle ruptures? Below, we address this question.

How to Manage a Ruptured Furuncle

Once a furuncle ruptures, wound cleaning and pharmacological treatment are required. Specific steps are outlined below:

1. Wound Cleaning

If the local infection is mild, after rupture, use sterile forceps or cotton swabs to remove the small purulent plug and exudate from the furuncle, followed by disinfection with povidone-iodine. In cases of severe infection with significant fluid or pus accumulation, irrigate the furuncle alternately with hydrogen peroxide and normal saline to remove necrotic tissue. Subsequently, pack the lesion with petrolatum gauze or iodoform gauze to facilitate drainage of wound secretions.

2. Pharmacological Treatment

Oral antibiotics—such as amoxicillin capsules or cefixime capsules—may be prescribed to prevent secondary infection. In severe cases, intravenous cefoperazone sodium injection may be necessary. After rupture, keep the wound surface clean and dry; disinfect daily with povidone-iodine and avoid contact with water. During recovery, avoid spicy or irritating foods (e.g., chili peppers, mustard) and alcohol consumption, as these may delay wound healing. Maintain a light, balanced diet in daily life to help prevent recurrence of furuncles.
