What is a Generic Drug?
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Product Details
Description
XARELTO (Rivaroxaban) is a medication used to treat or prevent blood clots in a number of different medical conditions. Blood clots that form in the deep vein system may break off and become lodged in the capillaries of the lungs, brain, or other organs. Damage from blood clots may be permanent and can be fatal.
Xarelto may be prescribed for the following:
- Prevent stroke and systemic embolism in nonvalvular atrial fibrillation
- Prevent deep vein thrombosis (DVT) in patients undergoing knee or hip replacement surgery
- Prevent recurrence of deep vein thrombosis (DVT) or pulmonary embolism (PE)
- Treat deep vein thrombosis (DVT) and pulmonary embolism (PE)
XARELTO (Rivaroxaban) works by preventing the function of the clotting factor Xa. The body forms clots through a complex system of proteins called clotting factors, and by inhibiting factor Xa, XARELTO (Rivaroxaban) slows the formation of blood clots.
