Impetigo is more than just a nuisance. It’s a common skin infection that can spread quickly, especially in children. But here’s the good news: it’s treatable, and with the right approach, it doesn’t have to be a major concern. Whether you’ve spotted the telltale crusty sores on your own skin or your child’s, understanding what impetigo is and how to manage it can make all the difference in preventing it from spreading further. In this article, we’ll dive into the symptoms, causes, and the best treatment options to help you tackle impetigo head-on. Let’s get started!
Impetigo is a highly contagious bacterial infection that affects the outer layer of the skin. Most commonly caused by either Streptococcus pyogenes or Staphylococcus aureus, it often starts as small, red sores that can break open and ooze fluid. Over time, the sores crust over into a distinctive golden or honey-colored scab. This infection is most common in children between the ages of 2 and 5, but adults can get it too.
Though impetigo is usually not serious, it can spread rapidly in environments where people are in close contact, such as schools or daycare centers. Early treatment is key to stopping it in its tracks.
The symptoms of impetigo are hard to miss. Here’s what to watch out for:
Red Sores: The infection often begins with red, inflamed bumps or blisters. These may appear on the face, especially around the nose and mouth, but can show up anywhere on the body.
Crusting: Once the blisters break, they begin to ooze a yellowish fluid, which later forms a crust that looks like dried honey or golden scabs.
Itching or Pain: The affected area can become itchy or even slightly painful, particularly when the sores are large or numerous.
Swollen Lymph Nodes: In more severe cases, you may notice swelling in the lymph nodes near the infected area.
These symptoms are classic signs of impetigo, but keep in mind that not all cases look the same. Some may be more localized, while others can spread quickly if left untreated.
Now, the good news: Impetigo is treatable! Whether you’re dealing with a mild case or a more widespread infection, there are effective treatments to clear up the infection quickly.
For most cases, doctors recommend topical antibiotics. These are applied directly to the infected skin, targeting the bacteria and preventing the infection from spreading.
Mupirocin (Bactroban): This is one of the most commonly prescribed treatments for impetigo. It’s a powerful antibiotic that targets both strep and staph bacteria. Apply it 2-3 times a day to the affected area until the infection clears, which usually takes about 7-10 days.
Retapamulin (Altabax): Another topical antibiotic, retapamulin is used for mild impetigo. It’s generally applied twice daily and is effective at targeting the bacteria causing the infection.
In some cases, impetigo can be more widespread or resistant to topical treatment. When that happens, oral antibiotics may be necessary to fully clear the infection.
Cephalexin (Keflex): This is an oral antibiotic commonly prescribed for impetigo, particularly when the infection is more extensive. It’s effective against both staph and strep bacteria.
Dicloxacillin: Another option for staph infections, dicloxacillin is effective at clearing up impetigo, especially in cases caused by antibiotic-resistant strains of staph bacteria.
Clindamycin (Cleocin): If you’re allergic to penicillin or other first-line antibiotics, clindamycin is a great alternative. It works well against a variety of bacteria, including those responsible for impetigo.
While antibiotics are essential for treating the bacterial infection, you can also take steps at home to manage the condition and prevent it from spreading:
Clean the Affected Area: Gently wash the infected skin with soap and water. Avoid scrubbing, as it could worsen the irritation.
Avoid Scratching: As tempting as it may be, scratching or picking at the sores can spread the infection. Keep the area covered with a clean bandage to help resist the urge.
Wash Hands Regularly: To avoid spreading impetigo, wash your hands frequently, especially after touching the infected area.
Keep Clothing and Bedding Clean: Change and wash any towels, sheets, or clothes that may have come into contact with the infected skin to prevent the bacteria from spreading to others.
