chorionic villus sampling (CVS) usually done before day 70 can cause
limb anomalies
medication class that has controlled studies that show no risk Ex: folic acid
category A
medication class that has studies in animals or humans that show fetal abnormalities or there is evidence of fetal risk based on human use and the risk clearly outweighs and benefit Ex: Isotretinoin (Acutain)
category X
medication class that has animal studies that do not show risk but there are no human studies or animal studies show adverse effects but this is not confirmed in human studies Ex: amoxicillin and augmentin
category B
medication class that has animal studies that show risk and there are no human studies or there are no human or animal studies Ex: Rifamoicin
category C
medication class that has positive evidence of human fetal risk but benefits for some women outweigh the risk Ex: phenytoin and ACE inhibitors
category D
side effects of marijuana use in pregnancy
Stimulate uterine contractions
Shortened gestation (dose dependent)
IUGR
