Uses
FRAGMIN Injection is indicated for the prophylaxis of ischemic complications in unstable angina and non-Q-wave myocardial infarction, when concurrently administered with aspirin therapy [see Clinical Studies (14.1)].
FRAGMIN is also indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE):
- In patients undergoing hip replacement surgery [see Clinical Studies (14.2)];
- In patients undergoing abdominal surgery who are at risk for thromboembolic complications [see Clinical Studies (14.3)];
- In medical patients who are at risk for thromboembolic complications due to severely restricted mobility during acute illness [see Clinical Studies (14.4)].
FRAGMIN is also indicated for the extended treatment of symptomatic venous thromboembolism (VTE) (proximal DVT and/or PE), to reduce the recurrence of VTE in patients with cancer. In these patients, the FRAGMIN therapy begins with the initial VTE treatment and continues for six months [see Clinical Studies (14.5)].
Limitations of Use
FRAGMIN is not indicated for the acute treatment of VTE.

Other Information
FRAGMIN Injection (dalteparin sodium injection) is a sterile, low molecular weight heparin. It is available in single-dose, prefilled syringes preassembled with a needle guard device, and multiple-dose vials. With reference to the W.H.O. First International Low Molecular Weight Heparin Reference Standard, each syringe contains either 2,500, 5,000, 7,500, 10,000, 12,500, 15,000 or 18,000 anti-Factor Xa international units (IU), equivalent to 16, 32, 48, 64, 80, 96 or 115.2 mg dalteparin sodium, respectively. Each multiple-dose vial contains either 10,000 or 25,000 anti-Factor Xa IU per 1 mL (equivalent to 64 or 160 mg dalteparin sodium, respectively), for a total of 95,000 anti-Factor Xa IU per vial.
Each prefilled syringe also contains Water for Injection and sodium chloride, when required, to maintain physiologic ionic strength. The prefilled syringes are preservative-free. Each multiple-dose vial also contains Water for Injection and 14 mg of benzyl alcohol per mL as a preservative. The pH of both formulations is 5.0 to 7.5 [see Dosage and Administration (2) and How Supplied (16)].
Dalteparin sodium is produced through controlled nitrous acid depolymerization of sodium heparin from porcine intestinal mucosa followed by a chromatographic purification process. It is composed of strongly acidic sulfated polysaccharide chains (oligosaccharide, containing 2,5-anhydro-D-mannitol residues as end groups) with an average molecular weight of 5,000 and about 90% of the material within the range 2,000–9,000. The molecular weight distribution is:
< | 3000 daltons | 3.0–15% |
3,000 to 8,000 daltons | 65.0–78.0% | |
> | 8,000 daltons | 14.0–26.0% |

FRAGMIN is administered by subcutaneous injection. It must not be administered by intramuscular injection.
FRAGMIN Injection should not be mixed with other injections or infusions unless specific compatibility data are available that support such mixing.
Routine coagulation tests such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) are relatively insensitive measures of FRAGMIN activity and, therefore, unsuitable for monitoring the anticoagulant effect of FRAGMIN [see Warnings and Precautions (5)].
2.1 Adult DosageProphylaxis of Ischemic Complications in Unstable Angina and Non-Q-Wave Myocardial Infarction: In patients with unstable angina or non-Q-wave myocardial infarction, the recommended dose of FRAGMIN Injection is 120 IU/kg of body weight, but not more than 10,000 IU, subcutaneously every 12 hours with concurrent oral aspirin (75 to 165 mg once daily) therapy. Treatment should be continued until the patient is clinically stabilized. The usual duration of administration is 5 to 8 days. Concurrent aspirin therapy is recommended except when contraindicated.

The usual duration of administration is 5 to 10 days.
In patients undergoing abdominal surgery associated with a high risk of thromboembolic complications, such as malignant disorder, the recommended dose of FRAGMIN is 5,000 IU subcutaneously the evening before surgery, then once daily postoperatively. The usual duration of administration is 5 to 10 days. Alternatively, in patients with malignancy, 2,500 IU of FRAGMIN can be administered subcutaneously 1 to 2 hours before surgery followed by 2,500 IU subcutaneously 12 hours later, and then 5,000 IU once daily postoperatively. The usual duration of administration is 5 to 10 days.
Medical Patients During Acute Illness: In medical patients with severely restricted mobility during acute illness, the recommended dose of FRAGMIN is 5,000 IU administered by subcutaneous injection once daily. In clinical trials, the usual duration of administration was 12 to 14 days.
Extended Treatment of Symptomatic Venous Thromboembolism in Patients with Cancer: In patients with cancer and symptomatic venous thromboembolism, the recommended dosing of FRAGMIN is as follows: for the first 30 days of treatment administer FRAGMIN 200 IU/kg total body weight subcutaneously once daily. The total daily dose should not exceed 18,000 IU. Table 3 lists the dose of FRAGMIN to be administered once daily during the first month for a range of patient weights

2.2 Dose Reductions for Thrombocytopenia in Patients with Cancer and Acute Symptomatic VTEIn patients receiving FRAGMIN who experience platelet counts between 50,000 and 100,000/mm3, reduce the daily dose of FRAGMIN by 2,500 IU until the platelet count recovers to ≥100,000/mm3. In patients receiving FRAGMIN who experience platelet counts < 50,000/mm3, discontinue FRAGMIN until the platelet count recovers above 50,000/mm3.
2.3 Dose Reductions for Renal Insufficiency in Extended Treatment of Acute Symptomatic Venous Thromboembolism in Patients with CancerIn patients with severely impaired renal function (CrCl < 30 mL/min), monitor anti-Xa levels to determine the appropriate FRAGMIN dose. Target anti-Xa range is 0.5–1.5 IU/mL. When monitoring anti-Xa in these patients, perform sampling 4–6 hrs after FRAGMIN dosing and only after the patient has received 3–4 doses.
2.4 AdministrationSubcutaneous injection technique: Patients should be sitting or lying down and FRAGMIN administered by deep subcutaneous injection. FRAGMIN may be injected in a U-shape area around the navel, the upper outer side of the thigh or the upper outer quadrangle of the buttock. The injection site should be varied daily. When the area around the navel or the thigh is used, using the thumb and forefinger, you must lift up a fold of skin while giving the injection. The entire length of the needle should be inserted at a 45 to 90 degree angle.
Inspect FRAGMIN prefilled syringes and vials visually for particulate matter and discoloration prior to administration
After first penetration of the rubber stopper, store the multiple-dose vials at room temperature for up to 2 weeks. Discard any unused solution after 2 weeks.
Instructions for using the prefilled single-dose syringes preassembled with needle guard devices
Fixed dose syringes: To ensure delivery of the full dose, do not expel the air bubble from the prefilled syringe before injection. Hold the syringe assembly by the open sides of the device. Remove the needle shield. Insert the needle into the injection area as instructed above. 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. Remove needle from the patient. Let go of the plunger and allow syringe to move up inside the device until the entire needle is guarded. Discard the syringe assembly in approved containers.
Graduated syringes: Hold the syringe assembly by the open sides of the device. Remove the needle shield. With the needle pointing up, prepare the syringe by expelling the air bubble and then continuing to push the plunger to the desired dose or volume, discarding the extra solution in an appropriate manner. Insert the needle into the injection area as instructed above. Depress the plunger of the syringe while holding the finger flange until the entire dose remaining in the syringe has been given. The needle guard will not be activated unless the entire dose has been given. Remove needle from the patient. Let go of the plunger and allow syringe to move up inside the device until the entire needle is guarded. Discard the syringe assembly in approved containers.
