## Quick answer

Which medicines are safe in pregnancy and breastfeeding? Check every medicine with a pharmacist, midwife, GP or specialist during pregnancy and breastfeeding, including pharmacy and herbal products. Do not stop prescribed medicine suddenly without advice, because untreated illness can also harm you or the baby. The safest choice depends on the medicine, dose, timing and reason it is needed.

General UK health information, not a diagnosis. In an emergency call 999 ; for urgent advice use [NHS 111](https://111.nhs.uk/) (GP out-of-hours in Northern Ireland).
