Commonly Prescribed Drugs Known to Cause Birth Defects

The March of Dimes reports that every year in the United States, about 150,000 babies are born with birth defects. Unfortunately, numerous prescription and over-the-counter medications carry a risk of causing fetal harm. As such, the U.S. Food and Drug Administration developed five pregnancy categories that indicate whether a drug is safe for pregnant women and to what extent. These categories include:

  • Category A: Studies indicate there is no fetal risk during the first trimester, nor is there any evidence of risk in later trimesters
  • Category B: Animal studies have failed to demonstrate fetal risk and there have been no well-controlled human studies
  • Category C: Animal studies have shown fetal risk, but there have been no well-controlled human studies; potential benefits may outweigh potential risks
  • Category D: There exists positive evidence of human fetal risk, but potential benefits may outweigh potential risks
  • Category X: Fetal abnormalities have been observed in animal or human studies and/or there exists positive evidence of human fetal risk; the risks clearly outweigh potential benefits

When a medication causes fetal harm, parents may be entitled to compensation for their child’s birth defect. An experienced Orlando injury attorney helps parents hold negligent pharmaceutical companies and reckless doctors and pharmacists accountable for the birth injuries they cause.
