Abstract
MPH is a common treatment for adult Attention Deficit Hyperactivity Disorder (ADHD). However, little information exists regarding its safety during pregnancy and thus, women with ADHD face difficult decisions regarding continued use during pregnancy. Here, Sprague-Dawley rats were orally treated 3x/day with 0 (control), 6 (low), 18 (mid), or 42 (high) mg MPH/kg/day (i.e., 0, 2, 6, or 14mg/kg at each treatment time) on gestational days 6-21. On postnatal days (PNDs) 1-21, all offspring/litter were orally treated 2x/day with the same dose. Righting reflex (PNDs 3-6) and slant board performance (PNDs 8-11) were assessed. T3, T4, E2, testosterone, LH and corticosterone were measured at PND 22. Separate pregnant dams and resulting litters were used for serum MPH measurements. MPH treatment had mild, but significant, effects on gestational body weight and food intake. Birth weight of high MPH offspring was 5% more than controls (p
