Maternal Trichomoniasis

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

An infection caused by the protozoan parasite Trichomonas vaginalis which affects 10 to 25% of women of reproductive age. It is a sexually transmitted disease.

There are anti-protozoal factors in breastmilk that destroy the parasite (May 1984, Gillin 1983).

No transmission of the parasite through breastmilk has been recorded. Maternal disease is not dangerous for a healthy infant (Lawrence 2016 p482).

The disease and its treatment are compatible with breastfeeding (Lawrence 2016 p806, OWH 2015). If a single mega-dose of metronidazole is given, some authors recommend waiting to breastfeed 12 hours after taking the medication. Tinidazole is preferable because of its lower excretion in milk (lower relative dose).

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.
