Quetiapine Fumarate

Very Low Risk

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. (Glocker 2021, Suttajit 2013, Mushtaq 2012, Sethi 2010, Gupta 2007, Atmaca 2002)

Expert authors consider the use of quetiapine to be safe or very probably safe during breastfeeding. (Hale, Lactmed, Uguz 2021, Teodorescu 2020, Rybakowski 2019, Pacchiarotti 2016, Schaefer 2015, Grover 2005, Larsen 2015, Parikh 2014, Rowe 2013)

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.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
