Toxicology patient information


Poisons advice

Patients and their relatives with enquiries concerning poisoning / overdose should contact NHS 111

Medical toxicology clinic

Patients with recognised or suspected poisoning are seen and assessed in the medical toxicology clinic, held weekly in Gassiott House, St Thomas’ Hospital. This clinic receives patient mainly from greater London and south east England, but can accept referrals from anywhere in the UK. Part of this clinic is a weekly dedicated 'club drug clinic where patients are seen by a clinical toxicologist with expert knowledge in issues related to the use of club drugs.

Patients must be referred by their GP or local hospital; we do not take direct referrals from patients.

Paediatric (children) cases will normally need to be reviewed by a local paediatrician prior to referral, for clinical assessment and examination.

Inpatient clinical toxicology service

This inpatient service provides specialist advice in the management of poisoned patients coming to St Thomas' Hospital. Patients admitted with problems related to poisoning will be assessed by a clinical toxicology consultant during one of their twice daily rounds.

Where appropriate the ongoing care of these patients is provided by the clinical toxicology team.

A specialist registrar in clinical toxicology and/or consultant is available on call to assess and/or provide advice on acutely poisoned patients who come to the emergency department (A&E)
