Author Information
Author(s): Barbara J. Struthers
Primary Institution: G.D. Searle & Co.
Hypothesis
Is metronidazole teratogenic when used during pregnancy?
Conclusion
Metronidazole does not appear to be associated with an increased risk of congenital anomalies in infants born to mothers who used it during pregnancy.
Supporting Evidence
- Studies show no significant increase in congenital anomalies among infants born to mothers treated with metronidazole.
- Metronidazole treatment may reduce the incidence of preterm birth and low birth weight.
- Controlled studies indicate that the risk of defects is similar to that of the general population.
Takeaway
Doctors can use metronidazole to treat infections in pregnant women without worrying about causing birth defects.
Methodology
Review of nearly four decades of literature on metronidazole use in pregnant women.
Potential Biases
Potential bias due to reliance on published reports and lack of detailed medical records.
Limitations
No controlled clinical trials specifically designed to determine teratogenicity in humans.
Participant Demographics
Pregnant women treated with metronidazole for various infections.
