Take antibiotics. Clean your wounds carefully. Monitor the wound for signs of infection. Keep your skin healthy.
This is the most common treatment for cellulitis. Treatment depends on the severity of the infection and your health, but it usually includes a prescription for oral antibiotics that will kill the infection. Cellulitis should begin to retreat within a few days, and disappear altogether within seven to ten days.  Your doctor may advise you to take 500mg of cephalexin by mouth every six hours. If MRSA is suspected, then your doctor may prescribe Bactrim, Clindamycin, Doxycycline, or Minocycline. Bactrim is most often prescribed for MRSA. Your physician will ask you to follow up within two to three days to report on the progress of the cellulitis. If it seems to be retreating, you'll need to take the full course of antibiotics (usually for 14 days) to ensure the infection is completely gone. Do not stop taking the antibiotics or skip doses because this can make it harder to treat the infection. Your physician will prescribe oral antibiotics if you are healthy and your infection is limited to the skin, but if the infection seems to be deeper and you're experiencing other symptoms, oral antibiotics won't be fast-acting enough. Cellulitis occurs most often when an open wound isn't properly dressed, leaving the skin open to bacterial infection. The best way to prevent this from happening is to take immediate measures to clean your wounds the second you get a scrape, cut or burn.  Wash the wound with soap and water. Continue washing it daily until it heals.  If the wound is large or deep, bandage it with sterile gauze. Change the bandage daily until the wound has healed. Check the wound every day when you remove the bandage to make sure it's healing properly. If it begins to swell, turn red or become itchy, you may need to seek medical treatment. If the wound seems to be draining, that's another sign that it might be infected, so make an appointment with your physician right away. Since cellulitis commonly affects people with skin disorders, taking good care of your skin is an important preventative measure. If your skin is sensitive or dry, or you have diabetes, eczema or another disorder that affects the skin, use the following techniques to keep your skin intact and prevent cellulitis from taking hold.  Moisturize your skin to keep it from flaking, and drink plenty of fluids to hydrate your body.  Protect your feet by wearing socks and sturdy shoes. Trim your toenails carefully so as not to accidentally cut your skin. Treat athlete's foot promptly, so it doesn't turn into a more severe infection.  Treat lymphedema to prevent your skin from cracking. Avoid activities that lead to cuts and nicks on your legs and feet (hiking through brushy areas, gardening, and so on).
