Hello,
Persistent Pulmonary
Hypertension in newborns (PPHN) is not only associated with immature lungs - it can occur in full-term infants as well. And, without doing an amniocentesis evaluation, we cannot say at what point the lungs are fully developed anyway. The studies that have determined an increased risk when the mother took
SSRIs after the 20th week in pregnancy did not evaluate the older tricyclic
antidepressants at all but generally they are considered just as the
SSRIs, to be safe when indicated for the benefit to the mother and baby when
depression puts them at risk.
I'm afraid the jury is still out on this and it is not known if PPHN is definitely associated with the use of the
antidepressants. More studies are needed on this. To avoid or withhold
antidepressants places pregnant women and their children at risk and, untreated,
depression in the mother has been associated with poor neonatal outcomes, including preterm birth, low birthweight, and lower Apgar scores. The risk of PPHN is small - less than 1% in infants exposed to
SSRIs in utero, so, many women with severe or recurrent illness may elect treatment with
SSRIs during pregnancy. If you are able to find alternative ways to treat the
depression, you may feel more confident that no harm will result because of your treatment.
Maternal smoking and use of
anti-inflammatory medication has also been implicated in PPHN. These facts often confuse the results because the mother may have other conditions going on at the same time.
I have not heard of an increase in this syndrome among mothers who used the tricyclic
antidepressants but those come with side effects of their own and many women find them unacceptable. Usually women respond best in pregnancy to the same treatment that worked before, if they were treated previously, so most experts believe it is not a good time to change their medication at this time.
Good luck.
