What are the treatments for the condition?

The condition is usually treated by discontinuing the drug that has caused the respiratory problem. In some cases, the person must continue to take the medication because of another medical condition. In other cases, irreversible lung damage may have occurred before the medication was stopped. These situations may require treatment with oxygen or other medications. Lung problems caused by an allergic reaction can be helped with corticosteroid drugs such as oral prednisone.

What are the side effects of the treatments?

If a drug has to be discontinued because of respiratory problems, the condition it was prescribed to treat may worsen or return. Other medications used to treat lung disease may carry side effects such as allergic reactions or stomach upset.

What happens after treatment for the condition?

Lung disease may go away after the medication is stopped. If this is the case, no further treatment is necessary. If irreversible lung damage has occurred, lifelong treatment may be needed.

How is the condition monitored?

The condition is monitored with breathing tests, known as pulmonary function tests, and by following a person's symptoms.
