# RIVAROXABAN 15 MG ## Short Description **Rivaroxaban 15 mg** is an oral anticoagulant belonging to the **direct oral anticoagulant (DOAC)** class. It is a **direct Factor Xa inhibitor** that helps prevent blood clots from forming or growing. Rivaroxaban may be prescribed for conditions such as **deep vein thrombosis (DVT), pulmonary embolism (PE), and prevention of stroke and systemic embolism in certain patients with non-valvular atrial fibrillation**. The appropriate strength and dosing schedule depend on the indication and kidney function. ## Key Benefits * Helps prevent and treat certain **blood clots**. * Helps reduce the risk of **stroke and systemic embolism** in eligible patients with non-valvular atrial fibrillation. * Used in the treatment of **deep vein thrombosis (DVT)**. * Used in the treatment of **pulmonary embolism (PE)**. * Helps prevent recurrence of DVT and PE when continued as prescribed. * Provides predictable anticoagulant activity without routine INR monitoring for most patients. ## Uses / Indications Rivaroxaban 15 mg may be prescribed for: * **Prevention of stroke and systemic embolism** in adults with non-valvular atrial fibrillation and appropriate risk factors. * **Treatment of DVT**. * **Treatment of pulmonary embolism (PE)**. * **Reduction in the risk of recurrent DVT or PE** in appropriate patients. * Other specific cardiovascular indications depending on the formulation, patient characteristics, and local prescribing guidelines. **Important:** Rivaroxaban 15 mg is not the correct dose for every indication. Some conditions require 2.5 mg, 10 mg, or 20 mg dosing. ## How It Works Rivaroxaban selectively and directly inhibits **Factor Xa**, an important enzyme in the blood-clotting process. Factor Xa is involved in the conversion of prothrombin to thrombin. By inhibiting Factor Xa, rivaroxaban reduces thrombin generation and therefore decreases the formation of **fibrin blood clots**. Unlike warfarin, rivaroxaban does not work by blocking vitamin K and generally does not require routine INR monitoring. ## Dosage & Administration The correct dose depends on the medical condition, kidney function, age, and other factors. ### Important examples of dosing * **Atrial fibrillation:** Rivaroxaban is commonly prescribed as **15 mg once daily with the evening meal** in adults with reduced kidney function within the approved range; patients with better kidney function may require 20 mg once daily. * **Treatment of DVT/PE:** Treatment commonly begins with a higher initial dose before transitioning to a maintenance dose. **15 mg twice daily for the first 21 days** is a commonly used regimen, followed by 20 mg once daily. * Other indications have different dosing schedules. ### Administration * Take rivaroxaban **exactly as prescribed**. * **15 mg and 20 mg tablets should be taken with food** to improve absorption. * Swallow the tablet with water. * Take it at approximately the same time each day. * Do not stop rivaroxaban without medical advice because stopping anticoagulation suddenly can increase the risk of serious blood clots. * If you miss a dose, follow the instructions specific to your prescribed regimen. Do not routinely double a once-daily dose. **Do not change between 15 mg and 20 mg doses without medical advice.** ## Side Effects The most important adverse effect of rivaroxaban is **bleeding**. Common or possible side effects include: * Easy bruising. * Nosebleeds. * Bleeding gums. * Prolonged bleeding from minor cuts. * Heavy menstrual bleeding. * Anemia. * Nausea. * Gastrointestinal discomfort. ### Serious Side Effects Seek immediate medical attention for: * Severe or uncontrolled bleeding. * Vomiting blood or material resembling coffee grounds. * Black, tarry stools. * Red or dark urine. * Severe headache, dizziness, weakness, or fainting. * Unexplained severe bruising. * Coughing up blood. * Severe abdominal pain. * Signs of a stroke, such as sudden weakness, difficulty speaking, or facial drooping. Spinal or epidural bleeding is a rare but serious complication associated with neuraxial anesthesia or spinal procedures. ## Precautions & Warnings * Rivaroxaban can cause **serious and potentially life-threatening bleeding**. * Tell your doctor if you have active bleeding or a condition that significantly increases bleeding risk. * Inform your healthcare professional about any history of stomach ulcers, gastrointestinal bleeding, liver disease, or kidney disease. * Kidney function should be assessed when determining the appropriate dose. * Some liver diseases may make rivaroxaban unsuitable. * Avoid unnecessary use of medicines that increase bleeding risk, particularly NSAIDs, unless advised by your doctor. * Inform your dentist and other healthcare professionals that you are taking rivaroxaban before procedures. * **Do not stop rivaroxaban abruptly** without medical advice. * Seek urgent medical attention after a significant head injury, especially if you develop headache, confusion, weakness, vomiting, or unusual drowsiness. * Tell your doctor if you are pregnant, planning pregnancy, or breastfeeding. * Rivaroxaban is not generally recommended for patients with **mechanical heart valves** or certain types of significant valvular disease. * Discuss any upcoming surgery, dental procedure, spinal injection, or epidural anesthesia with your healthcare team. ## Drug Interactions Rivaroxaban has clinically important interactions with medicines that affect bleeding or alter rivaroxaban levels. ### Medicines that may increase bleeding risk * **Aspirin**. * Clopidogrel and other antiplatelet medicines. * NSAIDs such as ibuprofen or naproxen. * Other anticoagulants, including warfarin, heparin, and other DOACs. * Certain antidepressants, including SSRIs and SNRIs, may increase bleeding risk. ### Medicines that may increase rivaroxaban levels Strong inhibitors of CYP3A4 and P-glycoprotein may increase rivaroxaban exposure, including certain: * Azole antifungals. * HIV protease inhibitors. * Other potent enzyme/transporter inhibitors. ### Medicines that may reduce rivaroxaban effectiveness Strong CYP3A4/P-glycoprotein inducers can reduce rivaroxaban levels, including: * Rifampicin. * Carbamazepine. * Phenytoin. * Phenobarbital. * St. John's wort. Always tell your doctor or pharmacist about **all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements** you take. ## Storage Information * Store at room temperature according to the manufacturer's instructions. * Keep in the original packaging. * Protect from excessive heat and moisture. * Keep the medicine away from direct sunlight. * Keep out of reach of children. * Do not use after the expiry date. * Dispose of unused medicine according to local pharmacy guidance. ## Prescription Status **Rivaroxaban 15 mg is a prescription-only anticoagulant in most countries.** It should be taken only under the supervision of a qualified healthcare professional because the dose depends on the indication, kidney function, and individual bleeding/clotting risks. ## Genuine Medicine Assurance When purchasing Rivaroxaban 15 mg, obtain it from a **licensed pharmacy or authorized medicine supplier**.
