Welcome to bumps

This website provides reliable, evidence-based, and accurate information about use of medicines in pregnancy, in the form of freely available patient information leaflets called 'Bumps' ('Best Use of Medicines in Pregnancy'). 

Bump leaflets are produced by the UK Teratology Information Service (UKTIS), a not-for-profit national organisation hosted by the Newcastle upon Tyne hospital NHS Foundation Trust and funded by the UK Health Security Agency (UKHSA) on behalf of the UK Health Departments. Bump leaflets are based on the scientific material UKTIS produces for healthcare professionals and incorporate information from all relevant published scientific studies.
