Two Antidepressants Taken During Pregnancy Linked To Heart Anomalies In Babies

Women who took the antidepressant fluoxetine during the first three months of pregnancy gave birth to four times as many babies with heart problems as women who did not and the levels were three times higher in women taking paroxetine.

Although some of the conditions were serious, others were not severe and resolved themselves without the need for medical intervention, according to a three-country study in the November issue of the British Journal of Clinical Pharmacology.

Researchers have advised women taking the drugs to continue unless they are advised to stop by their doctor or consultant. But they are being urged to give up smoking, as the study also found that more than ten cigarettes a day was associated with a five-fold increase in babies with major heart problems.

The team has also suggested that women on fluoxetine should be given a foetal echocardiogram in their second trimester to diagnose possible heart anomalies.

Antidepressants, Exercise, Age, Even Food Intake, Affect Generation Of New Brain Cells

Recent research shows that the production of new brain cells may be crucial for antidepressants to be effective and that the medication's effectiveness is strongly influenced by age. What's more, meal frequency, type of food, and physical exercise affect the brain's ability to manufacture these new cells.

For the first time in nonhuman primate models, scientists have documented the cause-and-effect relationship between antidepressant drugs and neurogenesis. The researchers found that the antidepressant drug fluoxetine improved the behavior of macaque monkeys with depression-like symptoms.

They also discovered that administering the drugs to normally behaving monkeys did not influence their behavior but did alter their brains by boosting neurogenesis in the hippocampus, an area involved in memory and learning.

Behavior therapy plus medication may help teens with depression and substance use disorders

The antidepressant fluoxetine combined with cognitive behavioral therapy appears as effective for treating depression among teens who also have substance use disorders as among those without substance abuse problems, according to a report in the November issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.

“Adolescents with substance use disorders (SUDs) have higher rates of depression (15 percent to 24 percent) than adolescents in the general population,” the authors write as background information in the article. “Comorbid [co-occuring] depression is also associated with more severe substance abuse, poorer drug treatment outcomes and higher relapse rates.”
