Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with betrixaban and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions.

Talk to your doctor about the risk of taking betrixaban.

Why is this medication prescribed?

Betrixaban is used to prevent deep vein thrombosis (DVT; a blood clot, usually in the leg) and pulmonary embolism (PE; a blood clot in the lung) in people who are hospitalized for serious illnesses and are at risk of developing a clot due to decreased ability to move around or other risk factors. Betrixaban is in a class of medications called factor Xa inhibitors. It works by blocking the action of a certain natural substance that helps blood clots to form.

How should this medicine be used?

Betrixaban comes as a capsule to take by mouth. It is usually taken with food once a day for 35 to 42 days. Take betrixaban at around the same time 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 betrixaban exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Continue to take betrixaban even if you feel well. Do not stop taking betrixaban without talking to your doctor. If you stop taking betrixaban, your risk of a blood clot may increase.

Other uses for this medicine

What should I know about storage and disposal of this medication?

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. http://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. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Symptoms of overdose may include the following:

What other information should I know?

Keep all appointments with your doctor.

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.
