Nintedanib

Nintedanib is used to treat idiopathic pulmonary fibrosis (IPF; scarring of the lungs with an unknown cause). It is also used to treat certain types of chronic fibrosing interstitial lung diseases (ILD; an ongoing disease in which there is increased scarring of the lungs). Nintedanib is also used to slow the rate of decline in lung function in people with systemic sclerosis-associated interstitial lung disease (SSc-ILD; also known as scleroderma-associated ILD: a disease in which there is scarring of the lungs that is often fatal). Nintedanib is in a class of medications called kinase inhibitors. It works by blocking the action of enzymes involved in causing fibrosis.

Nintedanib comes as a capsule to take by mouth. It is usually taken with food every 12 hours (twice a day). Take nintedanib capsules at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nintedanib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the capsules whole with liquid; do not chew or crush them.

Your doctor may need to decrease your dose or stop treatment if you experience certain severe side effects. Be sure to tell your doctor how you are feeling during your treatment.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. https://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.
