Nintedanib is a medicine used to treat idiopathic pulmonary fibrosis (IPF). IPF is a condition where your lungs become scarred and stiff, making it hard to breathe. It can also be used for some types of lung cancer in combination with other medicines.
Nintedanib is an anti-fibrotic medicine, which slows the process of scarring in your lungs by reducing the activity of your immune system.
Nintedanib won’t cure your lung condition or reverse any existing scarring, but it can slow down the development of the condition. Therefore, once you begin taking nintedanib, you may not “feel” different because nintedanib doesn't treat the symptoms of idiopathic pulmonary fibrosis and can't reverse the scarring already in your lungs.
