In severe cases of wheezing when the person cannot breathe effectively, a ventilator , or artificial breathing machine, may be needed. Treatment is then directed at the cause, when possible. For instance, antibiotics can be used to treat pneumonia. Medications can be used to control heartburn. Surgery, chemotherapy , or radiation therapy may be needed to treat a tumor or cancer.
Side effects depend on the treatments used.
All medications have possible side effects. For instance, antibiotics may cause allergic reactions , stomach upset, or headache. A ventilator may cause damage to the lungs or cause a lung infection. Surgery carries a risk of bleeding and infection. Severe wheezing from almost any cause may result in death if treatment is unsuccessful.
