Although Cipro is sometimes used for skin infections, I have only ever been prescribed penicillin for boils and abscesses in the past. As I am not a doctor, I am not in a position to say whether you should take the Cipro or not. Levaquin is used to treat bacterial infections of the skin, sinuses, kidneys, bladder, or prostate. Levaquin is also used to treat bacterial infections that cause bronchitis or pneumonia.
