Lactation Warnings


Pregnancy Warnings

  • Limited human data do not suggest a clear association for development toxicity. Animal data suggest no developmental toxicity at doses greater than 10 times the maximum recommended human dose. In women with poorly or moderately controlled asthma, evidence shows an increased risk of preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Consider maternal treatment benefits versus potential fetal/neonatal adverse outcomes.
