Welcome to bumps

This website is dedicated to providing 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 Public Health England 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.

We hope you find the information that you are looking for, if not, please complete our feedback form and let us know how we can improve our website.
