Today I read an article that disscusses the adverse effects of the antidepresants use during pregnancy. It says that when using antidepressant during pregnancy will causes hyperstension. The article is below.
One thing I want to emphase is that according to the authors of this study in the article, 4% to 14% of pregnant women are receiving antidepressants. Indeed, depression is one of the most commmon chronic illnesses among pregnant women. But should we use antidepressants during pregnancy? I check one of antidepresants – Paroxetine – one of the SSRIs on medscape. Paroxetine belongs to Pregnancy Category: D and has Teratogenic Effects: Paroxetine increases the risk of congenital malformations, particularly cardiovascular malformations.
As above I think pregnancy should be one of the contraindications of this SSRI due to the teratogenic effects. Maybe all SSRIs have the effect of teratogenicity during pregnancy, but 4% to 14% of pregnant women are receiving antidepressants, maybe also the SSRIs such as Paroxetine. So anyone can tell me in U.S. do the pregnant women receive SSRIs to treat depression?
Depression is one of the most common chronic illnesses among pregnant women, with a prevalence of approximately 20%. According to the authors of the current study, 4% to 14% of pregnant women receive antidepressants, and these medications are not without adverse effects. The use of selective serotonin reuptake inhibitors (SSRIs) during pregnancy is most associated with a modest increase in the risk for congenital abnormalities, including heart defects.
Less data suggest serious adverse events of antidepressants on the pregnancy itself. However, antidepressants generally increase levels of circulating serotonin, which can, in turn, raise blood pressure. Some previous research has suggested that antidepressants can increase the risk for pregnancy-induced hypertension and preeclampsia during pregnancy. The current study by De Vera and Bérard uses a large patient database to further investigate the association between pregnancy-induced hypertension and antidepressants.
Study Synopsis and Perspective
Women who use antidepressants while pregnant have an increased risk of developing pregnancy-induced hypertension, new research shows.
The increased risk is beyond the risk that could be attributed to their depression or anxiety disorders, Mary A. De Vera, PhD, from the University of Montreal, and Anick Bérard, PhD, from Sainte Justine Research Center, Montreal, Quebec, Canada, write.
“Antidepressants are used widely during pregnancy, up to 14% of pregnant women use them,” Dr. Bérard told Medscape Medical News. “Our study adds one more piece to the puzzle with regard to the risk of using antidepressants during pregnancy.”
The study is published online March 22 in the British Journal of Clinical Pharmacology.
Do Not Stop Meds
SSRIs are the main antidepressants in use today, and serotonin is a vasoconstrictor and also directly affects diastolic blood pressure, although the mechanism of action for this is not very well understood, Dr. Bérard noted.
In this study, the researchers analyzed data from the Quebec Pregnancy Registry and compared 1216 women who had been diagnosed with pregnancy-induced hypertension, with or without preeclampsia, who had no history of hypertension before they became pregnant, with 12,160 matched control individuals.
They found that among the participants with pregnancy-induced hypertension, 45 (3.7%) had used antidepressants during pregnancy, compared with 300 (2.5%) of the women in the control group (odds ratio [OR], 1.52; 95% confidence interval [CI] 1.10 – 2.09).
Antidepressant use during pregnancy was associated with a 53% increased risk for pregnancy-induced hypertension (OR, 1.53; 95% CI, 1.01 – 2.33). Use of SSRIs was associated with a 60% increased risk (OR, 1.60; 95% CI, 1.00 – 2.55); of the SSRIs, paroxetine was associated with the greatest risk for pregnancy-induced hypertension (OR, 1.81; 95% CI, 1.02 – 3.23).
“It is very important for physicians and women to discuss the risks and benefits of antidepressants before prescribing,” said Dr. Bérard.
“Close monitoring needs to be done, because there could be benefits, and there can also be risks. The message isn’t as simple as telling pregnant women to stop taking antidepressants.
“The decision has to be made one woman at a time. Anyone affected by this study should not stop taking their prescribed medication but seek a consultation with their doctor if they are concerned,” she said.
Linda Chaudron, MD, associate chair for clinical services in the Department of Psychiatry at the University of Rochester Medical Center in New York, said the study adds to recent studies that have explored the hypothesis of an association between antidepressant use and pregnancy-induced hypertension.
