Ketamine Overdose Symptoms

Overdose on ketamine, an anesthetic with hallucinogenic effects, can cause a person’s respiration levels to be negatively disrupted, making it harder for them to breathe.

Signs of a ketamine overdose include:

Nausea and/or vomiting.
Severe confusion.
Chest pain and irregular heart rate.
Paralysis.
Violence or terrors possibly related to hallucinations.
Seizures.
Extreme sedation.
Loss of consciousness or coma.
Heightened blood pressure.

Ketamine overdose can be fatal, although death from ketamine poisoning alone is rare. Since paralysis is a side effect of ketamine, if individuals start vomiting, they may choke on their vomit. Accidents and injuries related to the dissociative effects may also result in injuries and life-threatening consequences.
