## In brief

- A retrospective active-comparator cohort study found doxycycline use for respiratory tract infections or acne during early pregnancy was associated with an increased risk of pregnancy loss.
- The study was published in Annals of Internal Medicine.
- Doxycycline is a common antibiotic, and the findings concern women of childbearing age who use it frequently.

## Why it matters

The study reports an association, not proof of cause, but doxycycline is widely prescribed, so the finding bears on prescribing decisions and the evidence base for drug safety in pregnancy.
