Cellulitis requires antibiotic treatment. What you get depends on how serious your conditions is:
Severe: You’ll get antibiotics into a vein in your arm (the doctor will call this intravenous).
Mild: The doctor will give you oral antibiotics, like cephalexin and dicloxacillin.
Once the doctor prescribes an oral antibiotic for you, take it right away -- and finish the medicine as prescribed. Remember, cellulitis can be dangerous without proper treatment.
