What Are Warnings and Precautions for Eptifibatide?


Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Eptifibatide?”

Long-Term Effects

See “What Are Side Effects Associated with Using Eptifibatide?”



  • At the site of arterial sheath placement bleeding is the most common complication; minimize the use of arterial and venous punctures, intramuscular injections, and use of urinary catheters, nasotracheal intubation, and nasogastric tubes; when obtaining intravenous access, avoid non-compressible sites (e.g., subclavian or jugular veins)
  • Risk factors for bleeding include older age, a history of bleeding disorders, and concomitant use of drugs that increase the risk of bleeding (thrombolytics, oral anticoagulants, nonsteroidal anti-inflammatory drugs, and P2Y12 inhibitors); concomitant treatment with other inhibitors of platelet receptor glycoprotein (GP) IIb/IIIa should be avoided; in patients treated with heparin, bleeding can be minimized by close monitoring of aPTT and ACT
  • In patients undergoing PCI, treatment may increase in major and minor bleeding at the site of arterial sheath placement; after PCI, the infusion should be continued until hospital discharge or up to 18 - 24 hours, whichever comes first;
  • Heparin use is discouraged after PCI procedure; early sheath removal is encouraged while the drug is being infused; before removing the sheath, it is recommended that heparin be discontinued for 3 to 4 hours and an aPTT of fewer than 45 seconds or ACT less than150 seconds be achieved; in any case, both drugs should be discontinued and sheath hemostasis achieved at least 2 to 4 hours before hospital discharge; if bleeding at access site cannot be controlled with pressure, infusion of both drugs should be discontinued immediately
  • Thrombocytopenia
    • There have been reports of acute, profound thrombocytopenia (immune-mediated and non-immune mediated); in the event of acute profound thrombocytopenia or a confirmed platelet decrease to less than 100,000/mm3, discontinue drug and heparin (unfractionated or low-molecular-weight); monitor serial platelet counts, assess the presence of drug-dependent antibodies, and treat as appropriate
    • There has been no clinical experience with therapy initiated in patients with a baseline platelet count below 100,000/mm3; if a patient with low platelet counts is receiving the drug, their platelet count should be monitored closely

Pregnancy and Lactation

  • Available data on use in pregnant women from published literature and pharmacovigilance database is insufficient to establish a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes
  • Untreated myocardial infarction can be fatal to pregnant women and fetus
  • Myocardial infarction is a medical emergency in pregnancy that can be fatal to a pregnant woman and fetus if left untreated; therapy for a pregnant woman should not be withheld because of potential concerns regarding the effects of the drug on the fetus


  • There are no available data on the presence of the drug in human milk, effects on the breastfed infant, or milk production; as the drug is a peptide, it is likely to be destroyed in an infant’s gastrointestinal tract and not absorbed orally by the breastfed infant
