What are anti-fibrotics?
Anti-fibrotic medications like nintedanib and pirfenidone can slow down the build-up of scar tissue or fibrosis in the lungs and are usually used to treat idiopathic pulmonary fibrosis (IPF). These IPF treatments may reduce the rate that your lung fibrosis progresses. But they don’t stop the lung scarring completely or get rid of any scar tissue that has already formed.
If you don’t have idiopathic pulmonary fibrosis, find out about treatments for hypersensitivity pneumonitis or autoimmune diseases, such as rheumatoid arthritis and systemic sclerosis.
Nintedanib is an anti-fibrotic medication used to treat idiopathic pulmonary fibrosis. Your medical team will prescribe you nintedanib for as long as it’s helping you, unless you have significant side effects.
- Take nintedanib twice a day, ideally 12 hours apart, with or straight after food. Don’t chew or crush the capsule, but swallow it whole.
- Most people take 150mg of nintedanib twice a day. If your body can’t tolerate this dose, your medical team may put you on 100 mg twice a day if they think a reduced dose will help you.
- If you’re on nintedanib, your medical team will monitor you regularly to check it’s working and help you manage any side effects. You will also have regular blood tests to make sure your liver is healthy.
