description AIMS To investigate the transfer of amphetamines into breast milk following their recreational use and estimate drug exposure for the breastfed infant. METHODS Two breastfeeding mothers who were occasional recreational users of intravenous amphetamines were studied. A urine sample was collected 4 h after dose, and milk samples were collected over 24 h. Drug in urine was qualitatively identified by gas chromatography-mass spectrometry and quantification in milk was by high-performance liquid chromatography. Absolute infant dose via milk was estimated. RESULTS The urines contained predominantly methylamphetamine together with smaller amounts of amphetamine. In the 24 h after dose, average concentrations in milk were 111 mg l-1 and 281 mg l-1 for methylamphetamine and 4 mg l-1 and 15 mg l-1 for amphetaminein cases 1 and 2, respectively. Absolute infant doses for methylamphetamine plus amphetamine (as methylamphetamine equivalents) were 17.5 mg kg-1 day-1 and 44.7 mg kg-1 day-1, respectively, for cases 1 and 2. CONCLUSION These limited data suggest that breastfeeding should be withheld for 48 h after recreational amphetamine use.
