Lorazepam is a sedative benzodiazepine that is useful for a variety of medical indications, such as insomnia, anxiety, and seizures, and can be given in the form of a tablet or an injection.
Uses
Lt. Tamara Johansen used lorazep in an attempt to revive Jeremy Franklin, though she was not sure if it will work. Lorazepam administered intravenously is used in an attempt to make catatonic patients, specifically those suffering from catatonic schizophrenia, responsive, with generally positive results after only one administration.

Sgt. Spencer's sleeping medication was either a benzodiazepine or a drug that acted in the same manner, since he began experiencing severe withdrawal symptoms after exhausting his supply, leading to his suicide. Withdrawal from sleeping pills and anxiety pills is often deadly, either in itself or through suicide, as it causes extreme autonomic instability, hallucinations, delusions, and paranoia.
