Animal reproduction studies have not been conducted on this combination product. Epidemiologic data for acetaminophen, including a population based case-control study from the National Birth Defects Prevention Study (n= 11,610) and data from 26,424 live singleton births have shown no increased risk of major birth defects in children with first trimester prenatal exposure. In 2015, the US Food and Drug Administration released results of their evaluation on published research studies looking at mothers who took acetaminophen (either over the counter or as a prescription product) at any time during their pregnancy and the risk of attention deficit hyperactivity (ADHD) in their babies. They found all studies reviewed had potential limitations in their designs that prevented drawing reliable conclusions. Barbiturates have been reported to readily cross the placental barrier. A 2-day old infant whose mother had taken a butalbital-containing product during the last two months of pregnancy experienced withdrawal seizures; butalbital was found in the infant's serum. There are no controlled studies with this combination product in pregnant patients. US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
