Warning
Lorazepam has a risk for abuse and addiction, which can lead to overdose and death. Taking 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 take the smallest dose of lorazepam that works, and take it for the shortest possible time. Be sure you know how to take 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.
Precautions
Before taking lorazepam, tell your doctor or pharmacist if you are allergic to it; or to other benzodiazepines (such as alprazolam, clonazepam, diazepam); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney disease, liver disease, glaucoma, lung/breathing problems (such as sleep apnea), mental/mood disorders (such as depression, psychosis), personal or family history of a substance use disorder (such as overuse of or addiction to drugs/alcohol).

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be more sensitive to the side effects of this drug, especially loss of coordination and drowsiness. Loss of coordination and drowsiness may increase the risk of falling.

This drug may have the opposite of its usual calming effect in children, causing restlessness, shaking, or mental/mood changes (such as agitation, hallucinations).

Newborn babies of mothers who use this medication late in pregnancy may have symptoms such as slow/shallow breathing, nonstop crying, shaking, or trouble feeding. If you become pregnant, talk to your doctor right away about the risks and benefits of this medication.
This drug passes into breast milk. Consult your doctor before breastfeeding.
