Fragmin

Fragmin treats and prevents blood clots from developing in patients with multiple different conditions. Report any signs of bleeding such as bruising, blood in urine, stool, or vomit to your doctor.

Fragmin Overview

Updated: 

Fragmin is a prescription medication used to treat and prevent blood clots from developing in patients with several different medical conditions. Fragmin is also used to prevent further blood clots from developing in cancer patients who have already had a blood clot.

Fragmin belongs to a group of drugs called low molecular weight heparins or "blood thinners". These work by blocking the effects of enzymes involved in making blood clots. 

This medication comes in an injectable form to be given under the skin (subcutaneously) and is typically injected once or twice daily for a duration that is dependent on several medical factors. If Fragmin is to prevent blood clots from developing after surgery, Fragmin will be injected under the skin (subcutaneously) before surgery. 

Common side effects of Fragmin include bleeding, pain at the injection site, and upset stomach.

  3. Clean the area of skin where you will give the shot
  4. Make sure the drug is clear and colorless
  5. Take the cap off the needle

  7. Hold the syringe assembly by the open sides of the device and remove the needle shield
  8. You should be sitting or lying down to inject Fragmin
  9. Fragmin may be injected in a U-shape area around the navel, the upper outer side of the thigh, or the upper outer area of the buttock; the injection site should be varied daily
  10. Pinch a fold of skin between your finger and thumb and insert the needle into the injection area; the entire length of the needle should be inserted at a 45 to 90 degree angle
  11. Depress the plunger of the syringe while holding the finger flange until the entire dose has been given; the needle guard will not be activated unless the entire dose has been given 
  12. Release the skin after Fragmin is injected
  13. Remove needle and let go of the plunger and allow syringe to move up inside the device until the entire needle is guarded; do not rub the area of the injection

  • Simultaneous use of other drugs that affect blood clotting, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, and/or other anticoagulants.
  • A history of traumatic or repeated epidural or spinal punctures (LPs)
  • A history of spinal deformity or spinal surgery
