Psychostimulant and muscarinic cholinergic agonist.
Marketed in association with other drugs in products indicated, without proof of their efficacy, to improve memory and physical and mental fatigue.
Also used in cosmetic treatments.
Oral use.

At the date of the last update, the authors did not find any published data on its excretion in breast milk.

The limited pharmacokinetic data available (low molecular weight, high pKa) make it likely that it may be transferred to breast milk in a possibly significant amount.

Product with very few bibliographic references, marketed in few countries. Considered a drug of low therapeutic utility (SEFAP 2012, INSALUD 2001).

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.

In general, multiple drug combinations are not recommended, nor are drugs of unproven efficacy.


We do not have alternatives for C4 H11 NO.

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.
