Delirium tremens
Prevention is by treating withdrawal symptoms using similarly acting compounds to taper off the use of the precipitating substance in a controlled fashion. If delirium tremens occurs, aggressive treatment improves outcomes. Treatment in a quiet intensive care unit with sufficient light is often recommended. Benzodiazepines are the medication of choice with diazepam, lorazepam, chlordiazepoxide, and oxazepam all commonly used. They should be given until a person is lightly sleeping. Nonbenzodiazepines are often used as adjuncts to manage the sleep disturbance associated with condition. The antipsychotic haloperidol may also be used in order to combat the overactivity and possible excitotoxicity caused by the withdrawal from a GABA-ergic substance. Thiamine (vitamin B) is recommended to be given intramuscularly, because long-term high alcohol intake and the often attendant nutritional deficit damages the small intestine, leading to a thiamine deficiency, which sometimes cannot be rectified by supplement pills alone.
