Clinical evaluation

The diagnosis of opioid overdose is primarily based on history and physical examination. History of opioid use or abuse is a key factor. This history is often unavailable from the patient and must be obtained from family or bystanders. Drug paraphernalia found with the patient may lead to a suspicion of opioid overdose.
