New study looks at dangers of prescription drugs during pregnancy
The risk that a drug will cause malformations of an embryo or fetus is referred to as teratogenic risk. Did you know that the teratogenic risk of more than 80% of 468 drugs released in the USA over the last 20 years remains to be clarified?*
Today, prescription drug use during pregnancy is extremely common, with 44–99% of women being prescribed medication during pregnancy. Pregnant women and their unborn children are obviously a vulnerable population. Recent public health scares—for example H1N1— have only further underscored the need for more detailed research into medication use in pregnancy. It is understood that maternal physiological changes during pregnancy can alter drug pharmacokinetics and that placental transfer of medications may have unknown fetal consequences. As a recent study of the situation concludes, there is an urgent need for further research into the adverse effects of drugs used in pregnancy.*
Drugs used to treat depression linked to birth defects
SSRI refers to a drug that is a “selective serotonin reuptake inhibitor.” SSRIs are often considered anti-depressants because they are primarily used to treat depression. Six common name brand SSRIs are: Celexa (citalopram), Lexapro (escitalopram oxalate), Luvox (fluvoxamine), Prozac (fluoxetine), Paxil (paroxetine), and Zoloft (sertraline). Unfortunately, studies show that these drugs are linked to birth defects.**
For example, one study (published in the New England Journal of Medicine in 2007) of nearly 10,000 infants born with birth defects and nearly 6,000 healthy infants found that women who took sertraline (Zoloft) in the first few months of pregnancy had twice the risk of having a baby born with a heart defect. An earlier study (2006) found that, taken during the third trimester of pregnancy, Zoloft users are six times more likely to give birth to a child with persistent pulmonary hypertension of the newborn (PPHN).
Other birth defects reportedly linked to SSRI use while pregnant include: club foot, oral cleft, craniosynostosis and developmental delays.
