Warnings
Contraindications
Hypersensitivity
Active major bleeding, thrombocytopenia, history of CVA (within 2 years)
Peptic ulcer disease
Recent surgery of trauma, intracranial neoplasm, uncontrolled HTN, vasculitis
Oral anticoagulant use within 7 days increases bleeding risk
Cautions
Intended for use with aspirin and heparin, and has only been studied in that setting
Increased bleeding risk when used with thrombolytic agents
Monitor for thrombocytopenia
Pregnancy and lactation
Pregnancy category: C
Lactation: not known if excreted in breast milk; use caution
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.
