Bacterial infections are most commonly treated with antibiotics, explains Drugs.com. However, treatment options also depend on the specific underlying cause of the bacterial rash. Common types of bacterial skin infections include folliculitis, furuncles and carbuncles, according to Dr. Heather Brannon for About.com.
Small furuncles and mild cases of folliculitis may heal by themselves with good personal hygiene and wound care, states Dr. Brannon. Serious cases of furuncles and carbuncles may require treatment with antibiotics such as cephalexin or dicloxacillin. A procedure called incision and drainage may be needed if pus and induration are present. This procedure drains the pus and allows the lesion to heal from the inside out.
If the rash lasts more than a week or is accompanied by oozing and swelling skin, fever, chills, swollen glands or other cold-like symptoms, seek medical attention, recommends Drugs.com. It is also advised to seek professional help immediately if the rash is accompanied by hives, difficulty breathing, a quickened pulse, confusion or nausea. These are symptoms of a potentially life-threatening allergic reaction. Bacterial infection prevention methods include good personal hygiene such as frequently washing hands and bathing. Avoiding sharing clothes or personal hygiene items with other people also helps prevent infections.
