Diethylstilbestrol is a synthetic non-steroidal estrogen medication, which does not fall within the UK Health Security Agency’s remit.

Decisions on topics for new or updated guidance from the National Institute for Health and Care Excellence (NICE) are considered through an established NICE prioritisation process with decisions overseen by a prioritisation board, chaired by NICE’s Chief Medical Officer.
