If your health care provider thinks you might have diphtheria and are suffering from the toxic effects of the toxin, your health care provider will start you on treatment right away.
One treatment is called diphtheria antitoxin. Diphtheria antitoxin works to stop the toxin (or poison) that is in your body but has not yet attached to your tissue. Antitoxin is usually given intravenously (by IV).
Antibiotics (such as penicillin and erythromycin) are also needed to kill the diphtheria bacteria and keep it from spreading.
