The majority of the drugs consumed were compatible with breastfeeding(n=71, 97.2%), except for Phenobarbital (n=1, 1.4%) and Losartan (n=1, 1.4%. Conclusion: it was evidenced that medicine consumption during breastfeeding was high among nursing mothers, but most of the drugs presented low risk, that is, they were drugs compatible with lactation.
