A small number of observations seem to conclude that colistimethate is eliminated at low rates in milk, which together with the low intestinal absorption makes it unlikely that causes general disorders to the baby, but does not exclude a possible alteration intestinal as diarrhea or thrush.

The peak milk concentration is reached within five hours of intramuscular injection, while its level in milk can range from undetectable to 2100 mcg/L after an injection equivalent to 66 mg of colistin.

Warning of the manufacturer:

Colistimethate sodium is excreted in breast milk. It is advisable to administer to lactating women only when clearly needed.
