            Warnings

            Contraindications

            Severe hypersensitivity reaction to drug (i.e., anaphylactic reactions) or excipients

            History of thrombocytopenia following prior exposure to therapy

            Active internal bleeding or history of bleeding diathesis, major surgical procedure or severe physical trauma within previous month

            Cautions

            Bleeding is most common complication encountered during therapy; most bleeding associated with therapy occurs at arterial access site for cardiac catheterization; minimize use of traumatic or potentially traumatic procedures such as arterial and venous punctures, intramuscular injections, nasotracheal intubation, etc.

            Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases risk of bleeding

            Profound thrombocytopenia reported; monitor platelet counts beginning about 6 hr after treatment initiation and daily thereafter; If platelet count decreases to < 90,000/mm3, monitor platelet counts to exclude pseudothrombocytopenia; if thrombocytopenia confirmed, discontinue therapy and heparin; previous exposure to a glycoprotein (GP) IIb/IIIa receptor antagonist may increase risk of developing thrombocytopenia

            Pregnancy & Lactation

            Pregnancy

            While published data cannot definitively establish the absence of risk, available published case reports have not established an association with therapy during pregnancy and major birth defects, miscarriage, or adverse maternal or fetal outcomes

            Untreated myocardial infarction can be fatal to the pregnant woman and fetus; myocardial infarction is a medical emergency in pregnancy which can be fatal to pregnant woman and fetus if left untreated

            Animal data

            • Studies with intravenous doses up to 5 mg/kg/day (about 5 and 13 times maximum recommended daily human dose for rat and rabbit, respectively, compared on a body surface area basis) have revealed no harm to fetus

            Lactation

            There is no data on presence of drug in human milk, effects on breastfed infant, or on human milk production; however, the drug is present in rat milk; the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on breastfed child from therapy or from underlying maternal condition

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.
