Benzodiazepine overdose may occur with extremely high doses or, more commonly, when it is taken with other depressants. This risk is especially present with other GABAergic depressants, such as barbiturates and alcohol, since they work in a similar fashion but bind to distinct sites on the GABAA receptor, resulting in significant cross-potentiation.[citation needed]

Benzodiazepine overdose is a medical emergency that may lead to a coma, permanent brain injury or death if not treated promptly. Symptoms may include severe slurred speech, confusion, delusions, respiratory depression, and non-responsiveness. The user might seem like they are sleepwalking. The user is also more susceptible to consume more of the same or another substance due to their impaired judgement, which is typically not seen with other substances during overdose.

Benzodiazepine overdoses may be treated effectively in a hospital environment, with generally favorable outcomes. Care is primarily supportive in nature, although overdoses are sometimes treated with flumazenil, a GABAA antagonist[1] or additional procedures such as adrenaline injections if other substances are involved.[citation needed]
