About Rivastar-20 Tablet

Rivastar-20 Tablet is a prescription medicine used to treat and prevent harmful blood clots. It is commonly prescribed to protect people from strokes, deep vein thrombosis (clots in the legs), and pulmonary embolisms (clots in the lungs). By keeping your blood flowing smoothly, it lowers the risk of serious medical emergencies.

For this medicine to work effectively, you must take it consistently at the same time every day. Depending on the strength of your dose, your doctor may instruct you to take it with food to ensure your body absorbs it properly, or you may be able to take it with or without food. Making simple lifestyle adjustments, such as drinking enough water and staying active, can also support your treatment.

Like all medicines, Rivastar-20 Tablet can cause side effects, with mild bleeding or easy bruising being the most common. However, if you experience serious symptoms like coughing up blood, severe dizziness, or bleeding that will not stop, you should contact your doctor immediately.

Do not take this if you have active, severe bleeding or severe liver damage. Before starting, it is crucial to talk to your doctor if you have kidney disease, a history of bleeding problems, or a prosthetic heart valve.

This medicine can interact with other drugs, including common pain relievers like aspirin or ibuprofen, which can increase your risk of bleeding. You should also limit alcohol consumption and consult your doctor if you are pregnant, breastfeeding, or managing health conditions as an older adult.

Uses of Rivastar-20 Tablet

Rivastar-20 Tablet may be prescribed for the following conditions related to blood clot prevention and treatment: 

  • Deep vein thrombosis (DVT): Rivastar-20 Tablet helps by treating existing blood clots in the deep veins of your legs and preventing new ones from forming.
  • Pulmonary embolism (PE): This medicine treats blood clots that have travelled to your lungs and reduces the chance of them happening again.
  • Stroke prevention in atrial fibrillation: For people with an irregular heartbeat, Rivastar-20 Tablet lowers the risk of a dangerous blood clot travelling to the brain and causing a stroke.
  • Blood clot prevention after surgery: It is used to protect you from developing blood clots in your veins after undergoing hip or knee replacement surgeries.
     

Key Benefits

  • Reduces Stroke Risk: Helps lower the risk of stroke in people with conditions such as non-valvular atrial fibrillation.
  • Supports Recovery After Surgery: Helps prevent blood clots following major hip or knee replacement surgery, supporting a safer recovery.
  • Treats Existing Blood Clots: Helps prevent existing clots from becoming larger while reducing the risk of new clots forming.

How Rivastar-20 Tablet Works

Rivastar-20 Tablet contains rivaroxaban, which works by targeting a specific protein in your body called Factor Xa, which is essential for blood clotting. When you get a cut, your body uses these proteins to stick blood cells together to stop the bleeding. However, inside your blood vessels, unwanted clotting can block blood flow. By gently blocking the activity of Factor Xa, Rivastar-20 Tablet slows down your body's clotting process. This keeps your blood thin and moving smoothly through your veins and arteries, which prevents new clots from forming and stops existing clots from growing larger.
