<meta name="description" content="Modest doses of desvenlafaxine are excreted into breastmilk, but serum drug levels of breastfed infants are less than 10% of simultaneous maternal levels. Total drug exposure of breastfed infants is about half of that experienced by breastfed infants whose mothers are taking venlafaxine.[1]. With the related drug venlafaxine, newborn infants of mothers who took the drug during pregnancy sometimes experienced poor neonatal adaptation as seen with other antidepressants such as SSRIs or SNRIs. Similar effects may occur with desvenlafaxine. Monitor breastfed infants for excessive sedation and adequate weight gain if this drug is used during lactation, especially newborn or preterm infants.">

id="LM698.Summary_of_Use_during_Lactation"><h3>Summary of Use during Lactation</h3><p>Modest doses of desvenlafaxine are excreted into breastmilk, but serum drug levels of breastfed infants are less than 10% of simultaneous maternal levels. Total drug exposure of breastfed infants is about half of that experienced by breastfed infants whose mothers are taking venlafaxine.[<a class="bibr" href="#LM698.REF.1" rid="LM698.REF.1">1</a>]. With the related drug venlafaxine, newborn infants of mothers who took the drug during pregnancy sometimes experienced poor neonatal adaptation as seen with other antidepressants such as SSRIs or SNRIs. Similar effects may occur with desvenlafaxine. Monitor breastfed infants for excessive sedation and adequate weight gain if this drug is used during lactation, especially newborn or preterm infants.</p></div><div id="LM698.Drug_Levels"><h3>Drug Levels</h3><p>Desvenlafaxine (O-desmethylvenlafaxine) is an active metabolite of venlafaxine with similar antidepressant activity.[<a class="bibr" href="#LM698.REF.2" rid="LM698.REF.2">2</a>]</p><p><i>Maternal Levels.</i> Ten lactating women with postpartum depression who were an average of 4.3 (range 0.9 to 12.7) months postpartum were taking extended-release desvenlafaxine (Pristiq) from 4 to 35 days in doses of 50 to 150 mg daily or an average of 1.2 mg/kg daily (95% CI: 0.93 to 1.5 mg/kg daily). Each woman provided up to 8 milk samples over a 24-hour period. Peak milk concentrations occurred at an average of 3.3 hours after the dose. An exclusively breastfed infant in this study would have received an estimated 85 mcg/kg daily or 6.8% (95% CI: 5.5 to 8.1%) of the maternal weight-adjusted dosage.[<a class="bibr" href="#LM698.REF.1" rid="LM698.REF.1">1</a>]</p><p>A nursing mother was taking oral desvenlafaxine 250 mg and amisulpride 100 mg twice daily. Eight breastmilk samples were obtained over a 24-hour period with a breast pump. The average breastmilk concentration was 1.9 mg/L which equated to an infant dose of 0.29 mg/kg daily or 7.8% of the maternal weight-adjusted dosage.[<a class="bibr" href="#LM698.REF.3" rid="LM698.REF.3">3</a>]</p><p><i>Infant Levels.</i> Ten infants with an average age of 4.3 (range 0.9 to 12.7) months were breastfed (8 exclusively) during maternal use of desvenlafaxine in doses of 50 to 150 mg daily or an average of 1.2 mg/kg daily. The infants had an average serum desvenlafaxine level of 16 mcg/L, which averaged 4.8% of the simultaneous maternal serum concentration taken at about 6.5 hours after the maternal dose. Considering only the exclusively breastfed infants, infant exposure would have averaged 5.8% of the maternal serum concentration.[<a class="bibr" href="#LM698.REF.1" rid="LM698.REF.1">1</a>]</p><p>A nursing mother was taking oral desvenlafaxine 250 mg and amisulpride 100 mg twice daily for 12.6 weeks.

The infant's serum desvenlafaxine concentration 3.1 hours after the mother's daily dose was 13 mcg/L or 1.7% of the maternal serum concentration.[<a class="bibr" href="#LM698.REF.3" rid="LM698.REF.3">3</a>]</p></div><div id="LM698.Effects_in_Breastfed_Infants"><h3>Effects in Breastfed Infants</h3><p>Ten infants ranging in age from 0.9 to 12.7 months were breastfed (8 exclusively) during maternal use of desvenlafaxine in doses of 50 to 150 mg daily or an average of 1.2 mg/kg daily. Mothers were also taking lorazepam (n = 6), quetiapine (n = 5), lamotrigine (n = 2), levonorgestrel (n = 2), domperidone (n = 1), and temazepam (n = 1). Infants were studied after an average of 9 days of exposure (range 4 to 35 days) of desvenlafaxine exposure via breastmilk. At the time of the study, 7 of the 10 infants were at a lower growth percentile than at the time of birth. Examination by a pediatrician found that all infants were healthy and had Denver developmental scores that matched their age on the day of the study.[<a class="bibr" href="#LM698.REF.1" rid="LM698.REF.1">1</a>]</p><p>A woman with depressive type schizoaffective disorder was taking lurasidone 40 mg at night and desvenlafaxine 50 mg daily after giving birth.

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.

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.[<a class="bibr" href="#LM698.REF.7" rid="LM698.REF.7">7</a>] None of the mothers were taking desvenlafaxine.</p><p>In a study of 80,882 Norwegian mother-infant pairs from 1999 to 2008, new postpartum antidepressant use was reported by 392 women and 201 reported that they continued antidepressants from pregnancy. Compared with the unexposed comparison group, late pregnancy antidepressant use was associated with a 7% reduced likelihood of breastfeeding initiation, but with no effect on breastfeeding duration or exclusivity. Compared with the unexposed comparison group, new or restarted antidepressant use was associated with a 63% reduced likelihood of predominant, and a 51% reduced likelihood of any breastfeeding at 6 months, as well as a 2.6-fold increased risk of abrupt breastfeeding discontinuation.
