It is often the consequence of a drug overdose. Common symptoms include dizziness, disorientation, nausea, vomiting and oscillopsia. It may indicate a medical emergency requiring treatment at a poison control center. Aside from poisoning, a systemic infection may also lead to one. Classic toxidromes may be variable or obscured by co-ingestion of multiple drugs.

A common tool for assessing for the presence of toxidrome in the United Kingdom is the CRESS tool. thumb|upright=1.6|Toxidrome flowchart diagnosis
