Fragmin is a prescription blood thinner that contains dalteparin sodium, a low molecular weight heparin (LMWH). It’s given by injection to help prevent or treat certain blood clots.

Preventing blood clots (DVT/PE) after certain surgeries, or during acute illness with restricted mobility
Reducing clot-related complications in unstable angina or certain heart attacks

What Is A Generic?
×A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
