What is Rivaroxaban for?

Rivaroxaban belongs to a class of medications called Non-vitamin K antagonist oral anticoagulant (NOAC) or Direct Oral Anticoagulant (DOAC). It is used to treat blood clots, including that in deep veins and in major blood vessels in the lung, and to prevent potential stroke in atrial fibrillation patients (but not for those with abnormal heart valves). It is also used in patients with long-term ischemic heart disease.

How to use it?

Rivaroxaban can be taken orally.

 

For preventing stroke in atrial fibrillation, the usual dose is 20 mg once daily.

 

For preventing DVT or PE after surgery, the dose is 10 mg once daily for 35 and 12 days for hip and knee replacement respectively.

 

For treating DVT or PE, the initial dose is 15 mg twice daily for 21 days; followed by a maintenance dose of 20 mg once daily.

A lower dose is used in patients with poorer kidney function.

What are the side effects of Rivaroxaban?

The most common side effect is a higher chance of bleeding, for example, easier bruising, black tarry stools (gastrointestinal bleeding), and pink urine (bleeding in the urinary tract), which may lead to anemia.

Who should not take Rivaroxaban?

  • Anyone who is sensitive to Rivaroxaban or any ingredients in the medicine
  • Anyone with active bleeding

Pharmacist Tips:

  • As Rivaroxaban increases the chance of bleeding, be careful and avoid injury.
  • Use a soft toothbrush and an electric razor.
  • Make sure you take every dose, as you may risk potentially fatal blood clots.
  • If you have signs of abnormal bleeding, please find your doctor right away.

Common dosing schedule:
Rivaroxaban can be taken with or without food. Take it at the same time on a daily basis. Unlike conventional anticoagulants (e.g. Warfarin), Rivaroxaban has fewer dietary restrictions.

 

What if I miss a dose?
Rivaroxaban is usually taken once daily. If you remember it within 12 hours, take the missed dose immediately; if it is over 12 hours, skip the missed dose and go back to your normal dosing schedule. Do not take two doses at the same time. Please record the date of the missed dose and tell the doctor in the next follow-up.

 

This schedule is for reference only, adjustments may be made according to individual needs.
