Before prescribing a medicine that may matter in pregnancy, ask about the last period, contraception and pregnancy plans, and test where there is any doubt. A single question at the start prevents most exposures that later cause worry.
If a woman learns she is pregnant while on a drug, do not stop it at once without a plan: review the indication, the risk of the untreated condition, and alternatives together, and involve obstetric care early.
- Ask about last period, contraception and pregnancy plans before prescribing
- Test for pregnancy when there is any doubt
- Do not stop long-term treatment abruptly without a plan
- Involve obstetric care early when exposure has already occurred
Why it matters
Most early exposures happen before the pregnancy is known.
