How to Treat Cellulitis

Cellulitis is a bacterial skin infection that needs quick treatment. Without proper care, it can spread and become serious. The good news is that most cases clear up well with the right antibiotics and home care.

Antibiotic Treatment

Antibiotics are the main treatment for cellulitis. Your doctor will prescribe oral antibiotics for mild cases. Common choices include cephalexin, cefadroxil, or dicloxacillin. Take the full course of antibiotics as directed, usually 5 to 10 days, even if you start feeling better.

Most people see improvement within a few days of starting treatment. If your infection doesn't improve after 2-3 days of oral antibiotics, contact your doctor. You may need a different antibiotic or IV treatment.

Home Care Tips

While antibiotics work to fight the infection, these steps can help ease your symptoms:

• Elevate the affected area to reduce swelling

• Apply a cool, damp cloth to the area for comfort

• Take over-the-counter pain relievers like ibuprofen or acetaminophen

• Keep the area clean and dry

• Rest to help your body heal

When to Seek Emergency Care

Go to the emergency room right away if you have:

• Fever above 100.4°F (38°C) with chills

• Rapidly spreading redness or swelling

• Black or darkening skin

• Numbness or tingling in the affected limb

• Confusion, dizziness, or feeling very unwell

Hospital Treatment

Some people need hospital treatment with IV antibiotics. This includes those with severe symptoms, high fever, weakened immune systems, or infections that don't respond to oral antibiotics. IV antibiotics work faster and can handle more serious infections.

Preventing Future Infections

Cellulitis often comes back. To lower your risk: keep skin clean and moisturized, treat cuts and scrapes right away, manage conditions like athlete's foot that can create entry points for bacteria, and protect your skin from injuries. If you have repeated episodes, your doctor may prescribe preventive antibiotics.
