LSD Toxicity Medication

Medication Summary
If placing a patient who has used lysergic acid diethylamide (LSD) in a quiet environment with minimal stimuli is not effective, a benzodiazepine (lorazepam or diazepam) is the medication of choice, especially in patients with dysphoric reactions. Benzodiazepines decrease both central and peripheral sympathomimetic drug effects.
Benzodiazepines
Class Summary
These agents may be indicated for extremely agitated patients.
Diazepam (Valium)
Depresses all levels of CNS (eg, limbic and reticular formation), possibly by increasing activity of GABA.
Although seizures may be promptly brought under control, a significant proportion of patients experience a return to seizure activity, presumably because of the short-lived effect of diazepam after IV administration.
Lorazepam (Ativan)
May depress all levels of CNS (eg, limbic and reticular formation) by increasing activity of GABA, which is a major inhibitory neurotransmitter in the brain. Preferred due to longer duration of action.
