What are the indications for referral to a toxicology specialist in cases of suspected overdose?

Referral to a toxicology specialist, typically via the National Poisons Information Service (NPIS), is indicated for severe or complex cases of suspected overdose ¹. This includes situations involving multiple ingestions ¹.

Additionally, referral is advised for people with significant comorbidities ¹. Cases where the specific poison is unknown also warrant consultation with the NPIS ¹. The NPIS provides information and advice to NHS staff to assist in deciding whether a person needs admission or can be managed at home, and offers advice on hospital management for those requiring admission ¹. The service is available 24 hours a day and is supported by a team of on-call consultant clinical toxicologists ¹.
