Pirfenidone is a medication used to treat idiopathic pulmonary fibrosis (IPF), a lung disease that causes scarring and breathing difficulties. It helps slow down the progression of the disease. The usual adult dose is 400mg, taken three times a day with food to reduce stomach upset.

It's important to follow your doctor's instructions closely, as the dosage may be adjusted based on your response and any side effects. Common side effects include nausea, rash, and fatigue.

Always inform your healthcare provider about any other medications you're taking to avoid interactions.
