Pirfenex Tablet, Color : White

Pirfenidone is used to treat a certain lung disease called idiopathic pulmonary fibrosis (IPF). This disease causes the lungs to get scarred and become stiff, making it hard to breathe. Pirfenidone may help slow down the worsening of your IPF. Read the Patient Information Leaflet if available from your pharmacist before you start taking pirfenidone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
