Quetiapine Fumarate

Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

It is a dibenzothiazepine atypical antipsychotic (second generation antipsychotics and serotonin–dopamine antagonists).
It is used in the treatment of schizophrenia and of bipolar and other psychotic disorders, and borderline personality disorders.
Oral administration in two daily doses.

It is excreted into breast milk in clinically insignificant amounts (Yazdani 2018, Aydin 2015, Van Boekholt 2015, Rampono 2007, Misri 2006, Lee 2004, Seppala 2004).
Clinical or development problems in infants whose mothers were treated have not been observed, whether at the short or long term (Levesque 2016, Sharma 2016, Aydin 2015, Van Boekholt 2015, Newport 2009, Rampono 2007, Misri 2006, Ritz 2005, Gentile 2005, Seppala 2004, Lee 2004).
Very low plasma-levels of quetiapine in these infants were found (Rampono 2007).

Galactorrhea may occur with or without an increased of prolactin (Suttajit 2013, Mushtaq 2012, Sethi 2010, Gupta 2007, Atmaca 2002).

Expert authors consider the use of quetiapine to be very probably safe during breastfeeding (Hale, Lactmed, Schaefer 2015, Grover 2015, Larsen 2015, Parikh 2014, Rowe 2013).


We do not have alternatives for Quetiapine Fumarate since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.
