Dimeticone; Dimethicone

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Dimethicone is a fluid type of silicone with a methyl as organic group radical. Silicones are polymers of silicon tied to oxygen atoms with high molecular weight. Dimethicone is water repellent and it is used in creams, dressings for skin protection and pediculicides. An activated form of Dimethicone is Simethicone that is used for treatment of flatulence.

At latest update, relevant published data on excretion into breast milk were not found.

Because it is not absorbed through the skin or orally along with a high molecular weight, excretion into breast milk in significant amount or absorption by the infant gut is highly unlikely.

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.
