What is pirfenidon?

Pirfenidone is a medication used to treat idiopathic pulmonary fibrosis (IPF), a lung disease that causes the tissue to become stiff and scarred, making it difficult to breathe. It works by reducing inflammation and slowing down the growth of scar tissue in the lungs. Pirfenidone is taken in capsule form and is usually prescribed to be taken three times a day with food. It can have side effects such as nausea, diarrhea, and rash. Patients taking pirfenidone should be monitored for liver function and have regular lung function tests. It is important to discuss any potential risks and benefits of taking pirfenidone with your doctor before starting treatment.
