Carbarsona

Limited compatibility

Unsafe. Moderate/severe adverse effects. Compatible under certain circumstances. Follow-up recommended. Use safer alternative or discontinue breastfeeding from 5 to 7 T ½ . Read Commentary.

Carbarsone is an organic derivative of pentavalent arsenic that was used as an antiprotozoal drug to treat intestinal amebiasis (Chopra 1933). Today it is for veterinary use only in most countries.

At the time of the last update, we found no published data on its excretion in breast milk.

Product with very few bibliographic references and/or very old, marketed in few countries. The absence of known pharmacokinetic data does not allow predicting its possible excretion in breast milk.

Alternatives

  • Metronidazole (Safe product and/or breastfeeding is the best option.)
  • Tinidazole (Safe product and/or breastfeeding is the best option.)

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.
