Page "Lorazepam" Paragraph 11

Catatonia with inability to speak is responsive and sometimes controlled with a single 2-mg oral, or slow intravenous dose of lorazepam.

Symptoms may recur and treatment for some days may be necessary.

Catatonia due to abrupt or too rapid withdrawal from benzodiazepines, as part of the benzodiazepine withdrawal syndrome, should also respond to lorazepam treatment.

As lorazepam can have paradoxical effects, haloperidol is sometimes given concomitantly.
