Fragmin is a prescription medication used to prevent blood clots, including deep vein thrombosis (DVT) and pulmonary embolism (PE), and to treat various forms of thrombosis, such as arterial thromboembolism, unstable angina, and non-Q wave myocardial infarction.

Fragmin’s primary component is Dalteparin, a low molecular weight heparin (LMWH). It belongs to the class of anticoagulants or blood thinners. It works by inhibiting specific clotting factors and enzymes responsible for blood clot formation.

Use and Dosage

The recommended administration method for Fragmin Pre-Filled Syringe involves injecting it into the fatty tissue on the right or left side of the stomach, thigh, or buttocks. If you need to self-administer the medication, your doctor or nurse will provide instructions on how to do so safely.

To take Fragmin, sit down or lie down before administering the shot. Wash your hands before and after using the syringe. For each injection, rotate the injection site to prevent excessive irritation at any one location. Follow the instructions provided in the package insert or by your healthcare professional.

The pre-filled syringe comes with a safety needle device and is for subcutaneous use only. Before injecting, check the syringe visually for any particulate matter or discoloration, and do not use it if present. Pinch a fatty fold of skin between your fingers, hold the syringe in your other hand, and firmly insert the needle at the injection site. Press down on the plunger to inject the medication, and then release the pressure on the plunger before removing the needle to avoid bleeding or medication leakage. Dispose of the used syringe and needle safely according to local regulations.

Do not use Fragmin Pre-Filled Syringe if you observe cloudiness, leakage, or the presence of particles in the solution. Similarly, avoid using the medication if there is any discernible change in the color of the solution. If you notice any of these issues, contact your healthcare provider for further guidance.
