Medication exposure and spontaneous abortion: a case-control study using a French medical database.
First trimester drug exposure may increase spontaneous abortion risk. Certain medications, including non-selective monoamine reuptake inhibitors, were associated with higher risks, while H1 antihistamines showed a potential protective effect.
Area of Science:
- Obstetrics and Gynecology
- Pharmacology
- Reproductive Health
Background:
- Spontaneous abortion is a common pregnancy complication.
- Limited research exists on the association between drug exposure and spontaneous abortion risk.
- Understanding potential teratogenic effects of medications is crucial for prenatal care.
Purpose of the Study:
- To investigate the association between drug exposure during the first trimester of pregnancy and the risk of spontaneous abortion.
- To identify specific drug classes that may influence spontaneous abortion occurrence.
Main Methods:
- A nested case-control study was conducted using the French TERAPPEL medical database.
- Cases comprised women experiencing spontaneous abortion before 22 weeks of amenorrhea; controls were women who had live births.
- Multivariate logistic regression analyses were performed, adjusting for maternal age, obstetric history, and other substance use.
Main Results:
- The study included 838 cases and 4,508 controls.
- Increased spontaneous abortion risk was associated with exposure to non-selective monoamine reuptake inhibitors (OR=2.2), antiprotozoals (OR=1.6), and centrally acting antiobesity products (OR=3.4).
- Exposure to H1 antihistamines was associated with a reduced risk of spontaneous abortion (OR=0.6).
Conclusions:
- This study suggests potential associations between specific first-trimester drug exposures and spontaneous abortion risk.
- Non-selective monoamine reuptake inhibitors, antiprotozoals, and centrally acting antiobesity products may increase risk.
- H1 antihistamines might have a protective effect, warranting further investigation.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
