Levomilnacipran Hydrochloride

High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

Milnacipran active enantiomer. Serotonin and Norepinephrine selective re-uptake inhibitor antidepressant drug. Oral administration once daily.

Latest update failed to find relevant data on breastfeeding.

Pharmacokinetic data (low serum protein binding and high bioavailability) indicates that drug excretion into breast milk in significant amount is highly probable. Absorption by the infant is likely to be high as well.

Frequent and potential severe side effects have been found.

Until more published data is known about this drug in relation to breastfeeding, known safer alternatives are preferable, especially during the neonatal period and in the event of prematurity.

  • Maternal Depression (Moderately safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.)

The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
