Boxed warning

SPINAL/EPIDURAL HEMATOMAS Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include: • Use of indwelling epidural catheters • Concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants. • A history of traumatic or repeated epidural or spinal punctures • A history of spinal deformity or spinal surgery • Optimal timing between the administration of FRAGMIN and neuraxial procedures is not known Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary. Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis [see Warnings and Precautions (5.1) and Drug Interactions (7) ] . WARNING: SPINAL/EPIDURAL HEMATOMAS See full prescribing information for complete boxed warning.

Mechanism of action

Sourced from openFDA

Dalteparin is a low molecular weight heparin with antithrombotic properties. It acts by enhancing the inhibition of Factor Xa and thrombin by antithrombin.

Indications

Sourced from openFDA
  • FRAGMIN is a low molecular weight heparin (LMWH) indicated for • Prophylaxis of ischemic complications of unstable angina and non-Q-wave myocardial infarction ( 1.1 ) • Prophylaxis of deep vein thrombosis (DVT) in abdominal surgery, hip replacement surgery or medical patients with severely restricted mobility during acute illness ( 1.2 ) • Extended treatment of symptomatic venous thromboembolism (VTE) to reduce the recurrence in adult patients with cancer.

Warnings & precautions

Sourced from openFDA

• Hemorrhage: Use caution in conditions with increased risk of hemorrhage ( 5.1 ) • Thrombocytopenia: Monitor thrombocytopenia of any degree closely ( 5.2 ) • Benzyl Alcohol Preservative: Do not use multiple-dose formulations in neonates and infants as they contain benzyl alcohol ( 5.3 ) • Laboratory Tests: Periodic blood counts recommended ( 5.4 ) 5.1 Risk of Hemorrhage including Spinal/Epidural Hematomas Spinal or epidural hemorrhage and subsequent hematomas can occur with the associated use of low molecular weight heparins or heparinoids and neuraxial (spinal/epidural) anesthesia or spinal puncture. The risk of these events is higher with the use of post-operative indwelling epidural catheters, with the concomitant use of additional drugs affecting hemostasis such as NSAIDs, with traumatic or repeated epidural or spinal puncture, or in patients with a history of spinal surgery or spinal deformity [see Boxed Warning , Adverse Reactions (6.2) , and Drug Interactions (7) ] . To reduce the potential risk of bleeding associated with the concurrent use of FRAGMIN and epidural or spinal anesthesia/analgesia or spinal puncture, consider the pharmacokinetic profile of FRAGMIN [see Clinical Pharmacology (12.3) ]. Placement or removal of an epidural catheter or lumbar puncture is best performed when the anticoagulant effect of FRAGMIN is low; however, the exact timing to reach a sufficiently low anticoagulant effect in each patient is not known. No additional hemostasis-altering medications should be administered due to the additive effects.

Adverse reactions

Sourced from openFDA

The following clinically significant adverse reactions are described in more detail in other sections of the prescribing information . • Risk of Hemorrhage including Spinal/Epidural Hematomas [see Warnings and Precautions (5.1) ] • Thrombocytopenia [see Warnings and Precautions (5.2) ] • Benzyl Alcohol Preservative Risk to Premature Infants [see Warnings and Precautions (5.3) ] Most common adverse reactions (>1%) are: bleeding (including hemorrhage), thrombocytopenia (Type I), hematoma at the injection site, pain at the injection site, transient elevation of transaminases ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not accurately reflect the rates observed in practice. Hemorrhage The most commonly reported adverse reactions are hematoma at the injection site and hemorrhagic complications. The risk for bleeding varies with the indication and may increase with higher doses. Unstable Angina and Non-Q-Wave Myocardial Infarction Table 7 summarizes major bleeding reactions that occurred with FRAGMIN, heparin, and placebo in clinical trials of unstable angina and non-Q-wave myocardial infarction.

Use in specific populations

Sourced from openFDA

8.1 Pregnancy Risk Summary Available data from published literature and postmarketing reports have not reported a clear association with FRAGMIN and adverse developmental outcomes. There are risks to the mother associated with untreated VTE in pregnancy, and a potential for adverse effects on the preterm infant when FRAGMIN is used in pregnancy (see Clinical Considerations ) . In animal reproduction studies, there was no evidence of embryo-fetal toxicity or teratogenicity when dalteparin sodium was administered to pregnant rats and rabbits during organogenesis at doses 2 to 4 times (rats) and 4 times (rabbits) the human dose of 100 units/kg dalteparin based on the body surface area (see Data ) . Because animal reproduction studies are not always predictive of human response, FRAGMIN should be used during pregnancy only if clearly needed. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Pharmacokinetics

Sourced from openFDA
Metabolism
Adults Mean peak levels of plasma anti-Xa activity following single subcutaneous doses of 2,500 units, 5,000 units and 10,000 units were 0.19 ± 0.04 units/mL, 0.41 ± 0.07 units/mL and 0.82 ± 0.10 units/mL, respectively, and were attained in about 4 hours in most subjects. Absolute bioavailability in healthy volunteers, measured as the anti-Xa activity, was 87 ± 6%.

Overdosage

Sourced from openFDA

An excessive dosage of FRAGMIN Injection may lead to hemorrhagic complications. These may generally be stopped by slow intravenous injection of protamine sulfate (1% solution), at a dose of 1 mg protamine for every 100 anti-Xa units of FRAGMIN given. If the APTT measured 2 hours to 4 hours after the first infusion remains prolonged, a second infusion of 0.5 mg protamine sulfate per 100 anti-Xa units of FRAGMIN may be administered. Even with these additional doses of protamine, the APTT may remain more prolonged than would usually be found following administration of unfractionated heparin. In all cases, the anti-Xa activity is never completely neutralized (maximum about 60% to 75%). Take particular care to avoid overdosage with protamine sulfate. Administration of protamine sulfate can cause severe hypotensive and anaphylactoid reactions. Because fatal reactions, often resembling anaphylaxis, have been reported with protamine sulfate, give protamine sulfate only when resuscitation techniques and treatment for anaphylactic shock are readily available. For additional information, consult the labeling of Protamine Sulfate Injection, USP, products.
