Impetigo

Diagnosis

Diagnosis of impetigo is usually made by examining the sores on the skin. Most cases do not require lab testing.
If the sores do not improve with standard antibiotic treatment, your doctor may take a sample of the fluid from a sore to identify the bacteria and determine which antibiotics will work best. This is important because some bacteria have become resistant to certain medicines.

Treatment

Treatment for impetigo typically involves prescription mupirocin ointment or cream applied to the affected area two to three times daily for five to ten days.

Before applying the medicine:

• Soak the area in warm water or use a warm wet cloth for a few minutes

• Gently pat dry and remove any scabs so the medication can reach the infection

• Cover the area with a nonstick bandage to prevent spreading

For ecthyma or widespread impetigo, oral antibiotics may be prescribed. It is important to finish the full course of medication, even if the sores appear healed.

Self care

For mild, localized infections, over-the-counter antibiotic creams or ointments may help. Covering the sores with a nonstick bandage reduces the risk of spreading the infection.
Avoid sharing towels, clothing, athletic gear or other personal items while contagious.

Preparing for your appointment

When scheduling a visit, ask whether you should take any steps to prevent spreading the infection to others in the waiting area.

To prepare for your appointment, make a list of:

• Symptoms you or your child are experiencing

• Medications, vitamins and supplements currently taken

• Relevant medical conditions

• Questions you want to ask your doctor

Examples of helpful questions include:

• What might be causing the sores?

• Are tests needed to confirm the diagnosis?

• What treatment do you recommend?

• How can I prevent the infection from spreading?

• What skin care steps should I follow while healing?

What to expect from your doctor

Your doctor may ask questions such as:

• When did the sores begin?

• What did they look like at the start?

• Have there been recent cuts, scrapes or insect bites in the area?

• Are the sores painful or itchy?

• What improves or worsens the symptoms?

• Does anyone else at home have impetigo?

• Has this occurred before?
