You can use antibiotics to cure a bacterial folliculitis infection. Less-severe cases can be treated with a topical ointment such as bacitracin. Or your doctor may prescribe an antiseptic cleanser, such as povidoneiodine or chlorhexidine. For more severe infections, your doctor will prescribe an antibiotic pill, such as cephalexin, ofloxacin or dicloxacillin. Some infections, pseudomonas folliculitis among them, may not require any antibiotic pills unless the infection worsens.
