For the study, researchers observed a group of 300 pregnant women, most of whom did not suffer from depression but some either had a history of depression or reported becoming depressed during pregnancy. Of those observed, some took medication to treat their depression either for part of their pregnancy or for the entire pregnancy; some did not take medication and remained depressed; and some did not take medication and reported being depressed for only part of their pregnancy.

The research found that the women who took medication for the duration of their pregnancy and the women who did not take medication but still suffered with depression had a much higher rate of premature birth (20 percent) than the women who took no medication and recovered from their depression during their pregnancy (4 to 9 percent).

Antidepressants can also carry others risks to unborn babies. A 2005 scientific study showed a link between birth defects in babies born to women who took antidepressants during pregnancy. The recurrence was rare enough that some antidepressants are still considered viable options for pregnant women.

However, one antidepressant showed a greater risk to unborn children in the first trimester over other antidepressants, Paxil. As a result of the study, drug manufacturer GlaxoSmithKline updated the PRECAUTIONS subsection on the labeling for its popular antidepressant Paxil, citing a greater risk for overall birth defects, in particular heart defects.

Women who are pregnant or are considering becoming pregnant should consult with their doctors to determine what depression treatment is best for them.

Paxil Linked to Twice as Many Birth Defects

GlaxoSmithKline recently conducted a study of major birth defects in infants born to women who took antidepressants (including Paxil) during the first trimester of pregnancy.

In a study of more than 3,500 pregnant women, Paxil was linked to twice as many major birth defects as other antidepressants, according to the FDA.

Birth defects are very rare in the U.S., and it’s not certain what role, if any, Paxil played in the birth defects seen in the study, notes GlaxoSmithKline.

Changes have been made to the labeling information on pregnancy precautions that accompanies Paxil, says the FDA.

GlaxoSmithKline is a WebMD sponsor.

Most of the birth defects seen in the study were heart related; the most common heart malformations were ventricular septal defects, which are holes between the heart’s two main pumping chambers. These are common birth defects overall as well.

The study was a retrospective epidemiological study. That means it looked at large groups of people in hindsight. There was no data on birth defects in babies born to women who didn’t take antidepressants during early pregnancy.

From the Company to Doctors

It is “difficult” to determine whether Paxil caused those birth defects, says GlaxoSmithKline in a letter sent to doctors.

In the letter, the company notes that these findings differ from previous studies looking at birth defects and antidepressants.

Data from the large Swedish Medical Birth Registry hasn’t shown evidence of increased risk of major birth defects with antidepressants, including Paxil, notes GlaxoSmithKline.

GlaxoSmithKline spokespeople were not immediately available for comment.

Paxil’s Warning

Paxil’s official web site puts it this way:

“Tell your doctor if you are pregnant or plan to become pregnant as there is a potential risk to the fetus with [Paxil]. Some studies of [Paxil] in pregnant women have suggested a possible increased risk of malformations, while others have not shown such a risk.”

Antidepressants, including Paxil and others, such as Prozac and Zoloft, have been linked to withdrawal symptoms in babies born to mothers taking these medications. These antidepressants are known as selective serotonin reuptake inhibitors (SSRIs).

The Paxil web site also says: “Babies born to mothers who have taken antidepressants, including SSRIs such as Paxil, in the third trimester of pregnancy have reported complications, including difficulties with breathing, turning blue, seizures, changing body temperature, feeding problems, vomiting, low blood sugar, floppiness, stiffness, tremor, shakiness, irritability or constant crying. Tube feeding, help with breathing and longer hospitalization may be needed. There have also been reports of premature births in pregnant women exposed to SSRIs, including Paxil.

“Like many antidepressants, Paxil can be present in breast milk so tell your doctor if you are nursing.”
