Hi- Need to double check on this drug for compatibility with breastfeeding. Mom has Reflex Sympathetic Dystrophy, is currently pregnant and seeking info regarding continuing treatments. Mother has not been treated during pregnancy, wants to know if she can resume during lactation. For treatments, mom is given a tourniquet on arm, and then injections consisting of xylocaine, bupivicaine, heparin, versed and bretylium. Most appear immediately compatible with exception of versed, which info fortunately says disappears completely from milk in 4 hrs-- so far, so good. Bretylium, the other question mark, shows some concerns for pregnancy, but no breastfeeding data (Briggs). Can anyone give me further information as to whether this mother should be able to resume treatments, or alternatives? -Lisa Marasco, BA, LLLL, IBCLC
