Lorazepam may increase the risk of serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take certain opiate medications for cough such as codeine (in Triacin-C, in Tuzistra XR) or hydrocodone (in Anexsia, in Norco, in Zyfrel) or for pain such as codeine (in Fiorinal), fentanyl (Actiq, Duragesic, Subsys, others), hydromorphone (Dilaudid, Exalgo), meperidine (Demerol), methadone (Dolophine, Methadose), morphine (Astramorph, Duramorph PF, Kadian), oxycodone (in Oxycet, in Percocet, in Roxicet, others), and tramadol (Conzip, Ultram, in Ultracet). Your doctor may need to change the dosages of your medications and will monitor you carefully. If you take lorazepam with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care immediately: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
Lorazepam may be habit forming. Do not take a larger dose, take it more often, or for a longer time than your doctor tells you to. Tell your doctor if you have ever drunk large amounts of alcohol, if you use or have ever used street drugs, or have overused prescription medications. Do not drink alcohol or use street drugs during your treatment. Drinking alcohol or using street drugs during your treatment with lorazepam also increases the risk that you will experience these serious, life-threatening side effects. Also tell your doctor if you have or have ever had depression or another mental illness.
Lorazepam may cause a physical dependence (a condition in which unpleasant physical symptoms occur if a medication is suddenly stopped or taken in smaller doses), especially if you take it for several days to several weeks. Do not stop taking this medication or take fewer doses without talking to your doctor. Stopping lorazepam suddenly can worsen your condition and cause withdrawal symptoms that may last for several weeks to more than 12 months. Your doctor probably will decrease your lorazepam dose gradually. Call your doctor or get emergency medical treatment if you experience any of the following symptoms: unusual movements; ringing in your ears; anxiety; memory problems; difficulty concentrating; sleep problems; seizures; shaking; muscle twitching; changes in mental health; depression; burning or prickling feeling in your hands, arms, legs or feet; seeing or hearing things that others do not see or hear; thoughts of harming or killing yourself or others; overexcitement; or losing touch with reality.
Why is this medication prescribed?
Lorazepam is used to relieve anxiety. Lorazepam is in a class of medications called benzodiazepines. It works by slowing activity in the brain to allow for relaxation.
How should this medicine be used?

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to lorazepam.

You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
