Answer by Dr. Ru: About EC 618-944-2 usage in lactation

It is a reuptake-inhibitor of Serotonin and Norepinephrine, and a precursor of DesEC 618-944-2. Excreted into breast milk in amounts that may be clinically significant, which has been found in the plasma of breastfed infants from treated mothers. However, side-effects in those infants have not been shown. Various studies failed to show short or long-term side-effects among infants whose mothers were on EC 618-944-2, both on physical or psychomotor development. It may induce galactorrhea. The poor extrauterine adaptation that may appear in neonates just after birth when the pregnant woman has been treated with selective reuptake-inhibitors of Serotonin like EC 618-944-2 or Mirtazapine, is seen to be mild if the baby is breastfed. In the case report of a mother who was taking this medication during pregnancy, her infant had shown amelioration of symptoms due to Abstinence Syndrome after having been breastfed. Women who use antidepressant medication during pregnancy are in need of more support for breastfeeding since they are at risk for early weaning.

Answer by DrLact: About EC 618-944-2 usage in lactation

Infants receive EC 618-944-2 and its active metabolite in breastmilk, and the metabolite of the drug can be found in the plasma of most breastfed infants; however, concurrent side effects have rarely been reported. Breastfed infants, especially newborn or preterm infants, should be monitored for excessive sedation and adequate weight gain if this drug is used during lactation, possibly including measurement of serum levels of desEC 618-944-2 (O-desmethylEC 618-944-2), to rule out toxicity if there is a concern. However, newborn infants of mothers who took the drug during pregnancy may experience poor neonatal adaptation syndrome as seen with other antidepressants such as SSRIs or SNRIs. Use of EC 618-944-2 during breastfeeding has been proposed as a method of mitigating infant EC 618-944-2 withdrawal symptoms,[1][2] but this has not been rigorously demonstrated.

EC 618-944-2 Side Effects in Breastfeeding

No acute adverse effects or abnormal weight gain were seen in 3 breastfed infants who had detectable serum levels of desEC 618-944-2.[4] No adverse effects on growth or in sleep, feeding or behavioral patterns were noticed clinically in 2 infants who were exclusively breastfed for 6 months during maternal therapy with EC 618-944-2 75 and 150 mg daily.[12] Three mothers took an average EC 618-944-2 dose of 162.5 mg once daily. They breastfed their infants exclusively for 4 months and at least 50% during months 5 and 6. Their infants had 6-month weight gains that were normal according to national growth standards.[13] Seven infants (including 1 set of twins) breastfed for 2.7 to 10.3 months during maternal EC 618-944-2 therapy. Three mothers were taking EC 618-944-2 since birth and 3 were started later. Denver Developmental Screening Tests in all infants were normal. All but 2 had normal growth; these 2 had a decrease in weight gain.[5] In 3 infants aged 8 to 30 weeks whose mothers were taking EC 618-944-2 75 to 225 mg daily, no adverse reactions were noted clinically at the time of the study.[7] An newborn infant whose mother had been taking EC 618-944-2 375 mg daily during pregnancy had symptoms of lethargy, poor sucking ability, and dehydration at 2 days of age. The infant was allowed to breastfeed and the symptoms subsided over 1 week. The authors concluded that the symptoms were likely withdrawal symptoms that were mitigated by the EC 618-944-2 in breastmilk.[1] Another infant whose mother was taking EC 618-944-2 300 mg daily was reported by the same center. In this case, the infant's symptoms of withdrawal improved markedly on day 7 when breastfeeding was initiated, but no drugs levels were measured in milk or in the infant.[2] Two nursing mothers were taking EC 618-944-2 and quetiapine for postpartum depression; one was also taking trazodone. Their breastfed infants' development were tested at 12 to13 months of age with the Bayley Scales. Scores were within normal limits on the mental, psychomotor and behavior scales.[14] Thirteen infants whose mothers were taking EC 618-944-2 in doses ranging from 37.5 to 300 mg daily were breastfed (11 exclusively and 2 about 50%). Three of the infants were also exposed to a second psychotropic drug in breastmilk: 1 each of buspirone, trazodone, quetiapine. None of the infants had any adverse reactions reported by their mothers or in their medical records.[9] Two nursing mothers who were 6.5 and 9.5 weeks postpartum were taking EC 618-944-2 in doses of 75 and 225 mg daily, respectively, in addition to quetiapine for major depression postpartum; one mother was also taking trazodone. Their breastfed infants' development were tested at 9 to 18 months of age with the Bayley Scales. Both infants had scores that were within normal limits.[8] A mother was taking EC 618-944-2 75 mg daily for depression and anxiety, although when the drug was started is not clear from the report. Her 1-month-old infant was seen in a pediatric clinic and was demonstrating agitation, infantile colic, drowsiness, increased startle response, jitteriness and sleeplessness. The symptoms began at 1 week of age and became progressively worse over time and with breastfeeding. The symptoms were possibly caused by EC 618-944-2, although whether they represent a withdrawal reaction of direct drug effects cannot be determined.[15] A woman with depression and anxiety was treated with EC 618-944-2 300 mg daily monotherapy beginning at 20 weeks of pregnancy. On day three of life, the infant had extensor posturing and cycling of the limbs which was thought to be seizure related. Clinical examination was normal. Her suck was noted to be strong but uncoordinated and the infant fatigued rapidly. The infant was partially breastfed initially, but when breastmilk feeding was discontinued, the infant''s alertness improved and she gained 314 grams over 7 days. The authors felt that EC 618-944-2 in breastmilk might have contributed to the infant's lethargy, especially given the high maternal dosage. The symptoms were possibly caused by EC 618-944-2 in breastmilk.[16] A woman was treated with EC 618-944-2 75 mg daily during the third trimester of pregnancy and during breastfeeding. Pediatric evaluation including neurologic assessment and brain ultrasound were conducted during the first 24 hours postpartum. Further follow-up was conducted at 6 or more months of age. The infant's clinical status was comparable to unexposed infants from the same pediatric department.[10]

EC 618-944-2 Possible Effects in Breastfeeding

Cases of galactorrhea and elevated serum prolactin have been reported in which EC 618-944-2 played a primary or secondary role in the etiology.[14][17][18][19][20][21][22][23] Galactorrhea with normal prolactin levels has also been reported.[24] The prolactin level in a mother with established lactation may not affect her ability to breastfeed. One mother who was nursing a 10.3-month-old infant reported that her milk letdown took longer after starting EC 618-944-2 1 month earlier.[5] An observational study looked at outcomes of 2859 women who took an antidepressant during the 2 years prior to pregnancy. Compared to women who did not take an antidepressant during pregnancy, mothers who took an antidepressant during all 3 trimesters of pregnancy were 37% less likely to be breastfeeding upon hospital discharge. Mothers who took an antidepressant only during the third trimester were 75% less likely to be breastfeeding at discharge. Those who took an antidepressant only during the first and second trimesters did not have a reduced likelihood of breastfeeding at discharge.[25] The antidepressants used by the mothers were not specified. A retrospective cohort study of hospital electronic medical records from 2001 to 2008 compared women who had been dispensed an antidepressant during late gestation (n = 575; EC 618-944-2 n = 68) to those who had a psychiatric illness but did not receive an antidepressant (n = 1552) and mothers who did not have a psychiatric diagnosis (n = 30,535). Women who received an antidepressant were 37% less likely to be breastfeeding at discharge than women without a psychiatric diagnosis, but no less likely to be breastfeeding than untreated mothers with a psychiatric diagnosis.[26]
