Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

Used for treatment of insomnia.

It is excreted in non-significant clinical amount into breast milk.

Foods with high fat content may delay absorption by the gut. A low oral bioavailability decreases the pass of it from the mother's milk to the infant's plasma, except in prematures or in the early neonatal period, when a higher intestinal absorption may occur.

Not commercially available in Spain


We do not have alternatives for Zaleplon 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.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia
