What should I watch for while using this medication?

Visit your care team for regular checks on your progress. You may need blood work done while you are taking this medication. Your condition will be monitored carefully while you are receiving this medication. It is important not to miss any appointments.

Avoid sports and activities that might cause injury while you are using this medication. Severe falls or injuries can cause unseen bleeding. Be careful when using sharp tools or knives. Consider using an electric razor. Take special care brushing or flossing your teeth. Report any injuries, bruising, or red spots on the skin to your care team.

If you are going to need surgery or other procedure, tell your care team that you are using this medication.

Wear a medical ID bracelet or chain. Carry a card that describes your condition. List the medication and doses you take on the card.

What are the most serious risks of this medication?

Do not stop taking this medication without first talking to your care team. Stopping it can increase the risk of blood clots and stroke. Ask your care team if you should stop this medication before surgery or other procedures, such as dental work. They will tell you when to stop taking it. They will also tell you when you should start taking it again. They may prescribe another medication to prevent blood clots from forming.

People who take this medication and have a spinal procedure are at risk of forming a blood clot in the space around the brain or spinal cord. This could cause paralysis (not being able to move). The risk is higher in people who have spinal problems or injuries, have had spinal surgery in the past, and for those with a tube (catheter) in their back. Taking other medications that also affect bleeding, such as NSAIDs or other blood thinners, can also increase the risk. Your care team will watch you closely. Let them know right away if you feel pain, tingling, or numbness in your legs or feet.
