November, 2006 by LEE COHEN, M.D. Over the last year, several studies on possible neonatal effects of prenatal exposure to SSRIs have been reviewed in this column. These studies have raised concerns about potential risks, [...]
In 2006, GlaxoSmithKline (GSK) elected to change product label warnings for the antidepressant paroxetine (Paxil), advising against the use of this drug by women who are pregnant. This decision was based on preliminary studies which suggested an increase in the risk of cardiovascular malformations among infants exposed to paroxetine in utero. A recent study from the Motherisk Program in Toronto has reported on the outcomes of over 3000 paroxetine-exposed infants.
Q. I am currently talking Remeron for depression. I am about 16 weeks pregnant and doing well. I recently started working with a new psychiatrist, and my new doctor suggested that I switch to Prozac because he thought it would be safer for the baby. I am a little worried about making a change; I have never tried Prozac before and had a bad reaction (horrible anxiety and insomnia) when I tried Lexapro.
Over the past few years, multiple reports have raised questions regarding the safety of selective serotonin reuptake inhibitor (SSRI) antidepressants during pregnancy. Chambers and colleagues reported that exposure to SSRIs late in pregnancy may be associated with an increased risk of persistent pulmonary hypertension of the newborn (PPHN). In the general population, PPHN affects about 1 to 2 per 1000 live births. Infants with PPHN are typically full-term or near-term and present shortly after delivery with severe respiratory distress. In the worst cases, PPHN requires intubation and mechanical ventilation and may result in long-term morbidity. In 2006, Chambers and colleagues published an article linking SSRI use during late pregnancy to an increased risk of persistent pulmonary hypertension in the newborn. Based on the results of this analysis, the authors estimated the risk of PPHN to be about 1% in infants exposed to SSRIs late in pregnancy (after 20 weeks).
Over the past 15 years, multiple studies have addressed the reproductive safety of various antidepressants. Data on the overall teratogenicity of SSRIs has come from relatively small prospective observational studies, larger international birth registries, managed health care databases, and case series; these data have cumulatively supported the reproductive safety of fluoxetine and certain other SSRIs. In a recent meta-analysis including 1774 antidepressant-exposed infants, first trimester exposure to SSRIs was not associated with an increased risk of major malformations above the baseline of 2%-3% seen in the general population (Einarson & Einarson, 2005). The bulk of the data thus far has suggested that SSRIs are not major teratogens; however, concerns about the potential teratogenicity of SSRIs were first raised in 2005 when several preliminary studies suggested that paroxetine may be associated with a small increase in risk of congenital abnormalities.
As many of the traditional mood stabilizers used to treat bipolar disorder, including lithium and valproic acid, carry some teratogenic risk and the reproductive safety of other medications, including the atypical antipsychotic agents, has not been well-characterized, many women with bipolar disorder decide to discontinue their treatment during pregnancy. A new study from Dr. Adele Viguera and her colleagues at the Massachusetts General Hospital and the Emory University School of Medicine helps to better define the risks associated with discontinuing treatment during pregnancy.
At our clinic we have the opportunity to see patients at various stages of pregnancy. When we evaluate a patient while she is still in the planning stages, we may recommend changing medications to those that have a better studied safety profile during pregnancy and see how she does on those medications prior to conception. If that same patient came into our clinic for an evaluation, but was already pregnant, we may make different recommendations than if she was in the planning stages.
Infertility is a problem which has gained increased attention over the past several decades. While many factors may contribute to infertility, some medications may also affect reproductive functioning and thus may have an impact on fertility. This post will focus on the antipsychotic drugs, which are now used to treat many psychiatric disorders other than schizophrenia, including insomnia, anxiety disorders, major depression and bipolar disorder.
The interaction between specific birth control preparations and anti-epileptic medications should always be taken into consideration when developing a treatment approach, as taking the two simultaneously may decrease the birth control pill's effectiveness.
Most women experience some degree of sleep disturbance during pregnancy, and for a significant number of women sleep disruption may be quite severe. There are many different causes for sleep disturbance during pregnancy, and choosing the appropriate intervention relies on an accurate diagnosis of the problem.
