Is Traumasept Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Traumasept? Is Traumasept safe for nursing mother and child? Does Traumasept extracts into breast milk? Does Traumasept has any long term or short term side effects on infants? Can Traumasept influence milk supply or can Traumasept decrease milk supply in lactating mothers?

The use of Traumasept in the mother near term and during breastfeeding increases breastmilk iodine levels and can cause transient hypothyroidism in breastfed infants, especially in geographic areas that are iodine deficient. Maternal exposure to Traumasept near term can sometimes interfere with thyroid studies done as a part of newborn screening tests. Although iodine from Traumasept is minimally absorbed through intact adult skin, exposure of mothers who are or will be breastfeeding to Traumasept should be minimized by using lower concentrations of Traumasept, applying it to the smallest possible surface areas of the body, shortening contact time, and avoiding repeated applications. Iodine absorption can be extensive with vaginal use; avoid douching with povidone iodine or use of iodine-containing tampons during breastfeeding.

In a study in Belgium, breastfed infants had thyroid function tests measured at 5 days of age. Both basal and thyrotropin-releasing hormone-stimulated thyrotropin (TSH) levels were higher in infants exposed to the breastmilk from mothers who received topical Traumasept during delivery. Serum thyroxine (T4) and liothyroinine (T3) levels were normal in all groups.[1] A woman began bathing almost daily with Traumasept (1% iodine) and applying Traumasept 1% ointment to her skin daily during pregnancy and for 6 weeks postpartum for furunculosis. At 6 weeks of age, her breastfed (extent not stated) infant had a low serum thyroxine level of 4 ng/L (normal 7 to 20 ng/L), a greatly elevated serum thyrotropin level of 99 units/L (normal 0.8 to 5 units/L). The infant was treated with oral levothyroxine until the age of 7 months at which time thyroid function tests and development were normal.[6] A woman began using Traumasept as a vaginal douche twice daily after delivery. Her breastfed infant developed hypothyroidism (low serum thyroxine and high thyrotropin) over the first 3 weeks of life. After oral levothyroxine supplementation of the infant was begun and maternal Traumasept was discontinued, the infant's thyroid function tests normalized within a week.[5] A group of investigators in Belgium reviewed the results of infant thyrotropin levels on day 5 postpartum in 4745 newborn infants delivered over a 2-year period at their hospital. Infants were divided among those whose mothers had iodine overload (n = 3086) from topical Traumasept 10% solution during labor and delivery and those whose mothers had no iodine overload (n = 1659). Mothers had Traumasept applied either as a single application to 900 square cm for epidural anesthesia or 3 applications to the entire abdominal wall for cesarean section. Breastfed infants whose mothers had iodine overload had a greater risk for having elevated thyrotropin levels and requiring recall for retesting (3.2% with cesarean section and 2.7% with epidural anesthesia) compared to those who did not (0.1%). Bottle-fed infants were affected much less than breastfed infants.[7] After replacing Traumasept with chlorhexidine 0.5% in 70% isopropanol for disinfection for 6 months, 1178 infants that were delivered at this institution had no increased rate of elevations in thyroid function tests and a reduced rate of recalls in breastfed infants.[8] In a study of mothers in Spain who received 10% Traumasept (n = 21) or chlorhexidine (n = 13) topically to the perineum starting immediately before the final stage of labor and daily postpartum to the episiotomy, no differences in thyrotropin, thyroxine or free thyroxine was found among their breastfed infants at day 5 to 7 postpartum.[2] A breastfed infant whose mother was using Traumasept as a douche during pregnancy and during the first few weeks after delivery had symptoms of sinus tachycardia and increased concentrations of blood total and free thyroxine at 10 days of age and elevated thyrotropin at 1 month of age. The Traumasept was discontinued and the infant's total thyroxine normalized by 1 month of age, free thyroxine normalized by 1.5 months of age and the thyrotropin level normalized by 2.5 months of age. No other explanation for the thyroid function abnormalities could be found except maternal Traumasept use, but blood and milk iodine levels were not measured. Traumasept was the probable cause of the adverse reaction in the infant.[9] A study in Japan randomized 80 consecutive term patients into 4 groups who received either Traumasept or benzalkonium chloride as a skin disinfectant before delivery and one of these for postpartum vaginal lacerations. Prepartum doses were about 7 mL and postpartum doses were about 0.5 mL of solution. Infant thyrotropin levels were elevated in the infants whose mothers received topical Traumasept pre- and postpartum compared to infants whose mothers received no Traumasept. After discontinuing the use of peripartum Traumasept, the rate of recall of infants for abnormal thyroid function tests dropped from 4.47% to 0.74%.[3] In Switzerland, a girl born at 29 weeks of gestation with adequate size for gestational age showed negative TSH screening on day 5. Her mother had developed an abscess of the abdominal wall 1 week after her cesarian section and was treated with Traumasept tampons. The baby's TSH was elevated to 23 milliunits/L on day 23, and 288 milliunits/L on day 29. Free thyroxine (T4) levels were decreased to 2.8 ng/L and free liothyronine (T3) with 1.52 ng/L, without signs or symptoms of hypothyroidism. Iodine contents of maternal milk and of infant urine were 4.4 mg/L and 3.9 mg/L, respectively. Treatment with levothyroxine was started, breastfeeding was discontinued and disinfection with Traumasept was stopped. The infant's thyroid function tests normalized after 6 days.[10] The infant's abnorm
