Diazepam use while Breastfeeding. Drugs containing Diazepam: Valium, Diastat, Dizac, Diastat AcuDial, Valrelease, Diazepam Intensol, Diastat Pediatric, Zetran. Diazepam is excreted into breastmilk and it and its active metabolite, nordiazepam, accumulate in the serum of breastfed infants with repeated doses.
