Kind: research · Impact: medium

## In brief

- A new study suggests that taking doxycycline, a commonly prescribed antibiotic, during the first trimester of pregnancy may increase the risk of pregnancy loss.
- Doxycycline is a broad-spectrum antibiotic, meaning it targets a wide range of bacteria, and is often used to treat acne and respiratory infections.

## Why it matters

The finding concerns a widely prescribed drug taken in early pregnancy, so it bears on prescribing decisions. The available source excerpt does not give study details such as sample size or effect size.
