The Food and Drug Administration (FDA) has already approved this medication. Rivaroxaban is a type of medicine called anticoagulant that blocks certain clotting proteins in your blood. This drug comes as tablets with the dosage strengths of 2.5 mg, 10 mg, 15 mg, and 20 mg.
A blood clot is a clump of blood that has changed from a liquid to a gel-like or semisolid state. Clotting is a needed process that can prevent you from losing excessive blood in certain instances. When a clot forms inside one of your veins, it won’t always dissolve on its own. This can be a very dangerous and even life-threatening situation. An immobile blood clot generally won’t harm you, but there’s a chance that it could move and become dangerous. If a blood clot breaks free and travels through your veins to your heart and lungs, it can get stuck and prevent blood flow. This is a medical emergency. Certain risk factors increase your chances of having a blood clot. Common factors that might put you at risk for a blood clot may include:
- Age (over 65 years old)
- Bed rest
- Certain birth control pills
- Lengthy travel
Symptoms of a blood clot include:
- Throbbing or cramping pain
- Swelling, redness, and warmth in a leg or arm
- Sudden breathlessness
- Sharp chest pain that may be worse when you breathe in
- Cough or coughing up blood
- Blood clots can be life-threatening if not treated quickly.
Blood Clots being Dangerous
These usually form to stop the bleeding. However, it can sometimes form inside the blood vessels. This is unsafe because the clot can block the blood vessel. It may as well travel in the bloodstream. Eventually, it might get lodged in a blood vessel that supplies a vital organ such as the heart, brain, or lungs. Some conditions can increase the risk of blood clots forming inside the blood vessels because they disturb your normal blood flow. For instance, if you have fatty deposits on the walls of your blood vessels which is a type of fast irregular heartbeat, this can lead to platelets clumping together and starting off the clotting process.
How does the medicine work?
Blood clotting begins when blood cells called platelets clump together and produce chemicals that activate clotting factors in the blood. The activated clotting factors cause a protein called fibrinogen to be converted into another called fibrin. Fibrin binds the platelets together which forms a blood clot. Rivaroxaban works by binding to clotting factor Xa and ultimately decreases the formation of fibrin and makes the blood less able to clot.
How To Use
