Phenelzine Sulfate

High Risk

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

Antidepressant used in the treatment of atypical depression. Oral administration 3 to 4 times a day.

Since the last update we have not found any published data on its excretion in breast milk.

The few known pharmacokinetic data do not allow to predict the possible passage into breast milk.

It can cause galactorrhea and increased prolatin levels. (Meltzer 1982, Segal 1969).

Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in cases of prematurity.

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

Alternatives

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
