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.

- tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Be sure to mention any of the following: anticoagulants (”blood thinners”) such as warfarin (Coumadin, Jantoven); aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen (Advil, Motrin, others) and naproxen (Aleve, Anaprox, Naprelan); carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, Teril); erythromycin (E.E.S., Ery-Tab, Eryc); ketoconazole; laxatives; oral steroids such as dexamethasone (Decadron, Dexpak), methylprednisolone (Medrol), and prednisone; phenytoin (Dilantin, Phenytek); pirfenidone (Esbriet); rifampin (Rifadin, Rimactane, in Rifamate, in Rifater); or stool softeners. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor what herbal products you are taking, especially St. John’s wort.
- tell your doctor if you or anyone in your family has ever had a bleeding problem, if you have or have ever had liver or heart disease, diverticular disease (diverticulitis; small pouches in the lining of the large intestine that can become inflamed), or blood clots, and if you have had recent abdominal surgery.
- tell your doctor if you are pregnant, plan to become pregnant, or can possibly become pregnant. You should not start taking nintedanib until a pregnancy test has shown that you are not pregnant. You should not become pregnant while you are taking nintedanib; the medication may harm your unborn baby. Nintedanib may decrease the effectiveness of hormonal contraceptives (birth control pills, patches, rings, implants, or injections), so you should not use these as your only method of birth control. You must also use a barrier method of birth control (a device that blocks sperm from entering the uterus such as a condom or a diaphragm). Talk to your doctor about birth control methods that you can use during your treatment and for at least 3 months after your last dose of nintedanib. If you become pregnant while taking nintedanib, call your doctor immediately.
- tell your doctor if you are breastfeeding.
- tell your doctor if you use tobacco products. Cigarette smoking may decrease the effectiveness of this medication. You should stop smoking before you start taking nintedanib and avoid smoking during your treatment.
Dosage Of Nintedanib
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.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests before and during your treatment to check your body’s response to nintedanib.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
