If started early enough, antibiotics such as erythromycin can make the symptoms go away more quickly. Unfortunately, most patients are diagnosed too late, when antibiotics aren't very effective. However, the medicines can help reduce the patient's ability to spread the disease to others.

Infants younger than 18 months need constant supervision because their breathing may temporarily stop during coughing spells. Infants with severe cases should be hospitalized.

An oxygen tent with high humidity may be used.

Fluids may be given through a vein if coughing spells are severe enough to prevent the person from drinking enough fluids.

Sedatives (medicines to make you sleepy) may be prescribed for young children.

Cough mixtures, expectorants, and suppressants are usually not helpful and should NOT be used.

In older children, the outlook is generally very good. Infants have the highest risk of death, and need careful monitoring.
