Lorazepam has a risk for abuse and addiction, which can lead to overdose and death. Using this medication with alcohol or other drugs that can cause drowsiness or breathing problems (especially opioid medications such as codeine, hydrocodone) may cause very serious side effects, including death. To lower your risk, your doctor should have you use the smallest dose of lorazepam that works, and use it for the shortest possible time. Be sure you know how to use lorazepam and what other drugs you should avoid taking with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.

Suddenly stopping this medication may cause serious (possibly fatal) withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as headaches, trouble sleeping, restlessness, hallucinations/confusion, depression, nausea, or seizures. Withdrawal symptoms may sometimes last weeks to months.

This medication is used to treat serious seizures that do not stop (status epilepticus). It is also used before surgeries or procedures to cause drowsiness, decrease anxiety, and cause forgetfulness about the procedure or surgery.

Lorazepam belongs to a class of medications called benzodiazepines, which produce a calming effect on the brain and nerves (central nervous system). It is thought to work by increasing the effect of a certain natural chemical (GABA) in the brain.
