The data collected from more than four million American and Nordic women by researchers at Brigham and Women's Hospital show that the risk for having babies with heart deformities increases by 28 percent for pregnant mothers who are treated with methylphenidate drugs, which are commonly taken as medication for ADHD (attention deficit hyperactivity disorder).
This means for every 1,000 pregnant women who took methylphenidate drugs such as Ritalin and Concerta during their first trimester (first 90 days of pregnancy), three infants are born with a heart defect.
"Although the absolute risk is small, it is nevertheless important evidence to consider when treating young women of reproductive age and pregnant women," researcher Dr. Krista Huybrechts of Brigham and Women's Hospital said.
The researchers suggest that those with mild to moderate ADHD symptoms may be able to forego treatment during pregnancy. However, pregnant mothers with severe ADHD symptoms are advised to continue using their medication throughout the nine months of gestation.
"Medications used to treat [ADHD] are increasingly used by women of childbearing age as well as by pregnant women," said Dr. William Cooper, in a commentary on the study. "Because nearly half of pregnancies are unplanned, women could be taking a prescription medication and become pregnant without being aware of the [associated] risks."
Previous studies have linked ADHD medication to heart risks. A 2014 study published in the Journal of Child and Adolescent Psychopharmacology found that children taking ADHD medications are twice as likely to develop rare heart problems.

Meanwhile, a 2016 study published in The BMJ found that cases of arrhythmia, or irregular heartbeats, were more likely to occur during the first two months of methylphenidate treatment.
ADHD is a chronic disorder that affects about 4.1 percent of American adults. The number of people taking ADHD medication is steadily rising, with a 36 percent incline in 2008 and 2012. The biggest spike in this statistic is seen in young women, between the ages of 19 and 34.
Amphetamines and methylphenidate are stimulants that increase activity in the body. They are considered the first-line medication for managing ADHD. However, many medications have been proven to lead to adverse side effects, such as sleep problems, mood swings, and loss of appetite.
