<unk>  is poisoning due to excessive doses of<unk> s. Symptoms typically include difficulty thinking, poor coordination, decreased level of consciousness, and a decreased effort to breathe (respiratory depression). Complications of<unk>  can include noncardiogenic pulmonary edema. If death occurs this is typically due to a lack of breathing.<unk>  may occur by accident or purposefully in an attempt to cause death. The toxic effects are additive to those of alcohol and benzodiazepines. The lethal dose varies with a person's tolerance and how the drug is taken. The effects of<unk> s occur via the GABA neurotransmitter. Exposure may be verified by testing the urine or blood. Treatment involves supporting a person's breathing and blood pressure. While there is no antidote, activated charcoal may be useful. Multiple doses of charcoal may be required. Hemodialysis may occasionally be considered. Urine alkalinisation has not been found to be useful. While once a common cause of<unk> ,<unk> s are now a rare cause.
