title: The safety of antituberculosis medications during breastfeeding.
abstract: Most antituberculosis drugs appear to be safe for use with breastfeeding. These agents are excreted in breast milk at relatively small concentrations. No adverse effects have been reported to date. The percentages of the therapeutic dose of antituberculosis agents that potentially may be delivered to the nursing infants range from 0.05% to 28%. Currently isoniazid, rifampin, ethambutol, streptomycin (first-line agents), kanamycin and cycloserine (second-line agents) are the only agents considered by the AAP to be compatible with breastfeeding. Unfortunately, there are still no clear data on the safety of pyrazinamide, ethionamide, and capreomycin during breastfeeding. If the mother chooses to breastfeed, it may be prudent to examine the infant for signs and symptoms of toxicity. In infants requiring treatment with antituberculosis agents, it is important to use therapeutic doses since drug concentrations in breast milk are not adequate as effective therapy for treatment or prevention. However, dosing at the lower end of the therapeutic range should be prescribed (i.e., 10 mg/kg/day of isoniazid) to decrease the risk of toxicity.
