What is drug-induced pulmonary fibrosis? | Action for Pulmonary Fibrosis

Certain medications can cause inflammation and scarring or fibrosis of the lungs. This usually affects older people.

Causes of drug-induced pulmonary fibrosis

Drugs that can cause pulmonary fibrosis include:

the antibiotic nitrofurantoin
anti-cancer drugs such as bleomycin
cardiac medications such as amiodarone and
biological therapies used for treating cancer and autoimmune diseases.

If you have pulmonary fibrosis, it is advisable to avoid these medications.

Drug-induced pulmonary fibrosis can be an idiosyncratic reaction. This means it may occur quickly after starting the drugs and is not associated with the dose of treatment.

Symptoms of drug-induced pulmonary fibrosis

The symptoms include cough and breathlessness. In some cases, drug-induced lung disease can be associated with fevers, fatigue and joint pains. Find more about pulmonary fibrosis and its symptoms.

Treatments

You will be advised to stop taking the drug to help to prevent further damage to the lungs. You may also be prescribed immunosuppressive therapies such as steroids to help to reduce the body’s immune response to the medication. Oxygen therapy may be required if your oxygen levels are low.

Ongoing treatment

You’ll have regular appointments with your medical team to monitor your lung disease.

Outlook and prognosis

If drug-induced pulmonary fibrosis is diagnosed quickly and the drugs stopped, most people make a good recovery.

But if it is not identified early, drug-induced pulmonary fibrosis can progress and be life-limiting. The prognosis depends on the drug, the extent of pulmonary fibrosis and the overall health of the patient.
