The PT and INR help a provider monitor how well warfarin is working to prevent blood clots. Official product monographs mention a study in 15 women.Label,17 Warfarin was not detected in the breast milk of any woman and 6 infants were documented as having normal prothrombin times. Her infant had a normal INR of 1.0 and prothrombin time of 10.3. The infant in this case has an increased prothrombin time of 33.8 s three weeks previous but this was judged not to be due to warfarin exposure.

If this drug is usedduring pregnancy, or if the patient becomes pregnant while taking this drug, the patient should beapprised of the potential hazard to a fetus [see Use In Specific Populations].
