What we do


The Welsh Medicines Advice Service (WMAS) provides local, regional and national services. Regional services are provided to local Medicines Advice services and other organisations in our region. WMAS Cardiff centre has resources that are additional to those held by local services.

Like all regional Medicines Advice services, WMAS Cardiff centre provides specialist services at a national level to support other regional services and provide information.
