Legal Drugs During Pregnancy

Effects of Prescribed and Over the Counter Drugs While Pregnant

There is a number of prescribed and over the counter drugs that are dangerous to the child while it is still in the womb. Some drugs only effect the fetus in certain trimesters of the pregnancy. Like the use of Codeine (a) in the first trimester is associated with inguinal hernias, cardiac and circulatory system defects, cleft lip and palate, muscle and skeletal defects. A full dose of aspirin may cause premature closure of the ductus arteriosus in the third trimester, as well as prolongation of gestation and labor. Anticoagulants, in the first trimester, like Warfarin, may result in fetal warfarin syndrome (FWS). Warfern also causes neonatal respiratory distress which occurs frequently due to upper airway obstruction. If it is used in the second and/or third trimester it may cause blindness, optic atrophy, and defects in the eyes. Most of the danger can be avoided if the drug is not taken in certain trimesters.
