Does anyone have any experience with abdominal pain/colic in a breastfed infant whose mom is on warfarin? I've been working with a mom of a four week old colicky baby. Mom has been treated with a decreasing dose of warfarin (dosage now 5mg) for deep vein thrombosis since shortly after delivery. Mom is exclusively nursing. Despite having received several medical opinions on the safety of warfarin, she is concerned that it might be contributing to her baby's evident abdominal pain. Mom has been on a dairy-free diet for 5+ days, and sees no improvement. As stomach pain is listed as a side-effect for mom, she is concerned that the colic pains might be a sign of overdose in her baby. We have worked with several colic-relief strategies with no results as yet. I would appreciate any feedback regarding this. TIA! Cindy Turner-Maffei, MA, IBCLC Massachusetts, USA
