What is the most important information I should know about lorazepam?
Lorazepam may be habit-forming. Misuse of habit-forming medicine can cause addiction, overdose, or death.
What should I discuss with my healthcare provider before taking lorazepam?
It is dangerous to purchase lorazepam on the Internet or from vendors outside the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. The sale and distribution of lorazepam outside the U.S. does not comply with the regulations of the Food and Drug Administration (FDA) for the safe use of this medication.
You should not take lorazepam if you have:
- narrow-angle glaucoma;
- myasthenia gravis; or
- a history of allergic reaction to any benzodiazepine, such as diazepam (Valium), chlordiazepoxide, clonazepam, flurazepam, and others.
To make sure lorazepam is safe for you, tell your doctor if you have:
- seizures or epilepsy;
- kidney or liver disease (especially alcoholic liver disease);
- asthma or other breathing disorder;
- open-angle glaucoma;
- a history of depression or suicidal thoughts or behavior;
- a history of drug or alcohol addiction; or
- if you use a narcotic (opioid) medication.
Do not use lorazepam if you are pregnant. This medicine can cause birth defects. Your baby could also become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant. Use effective birth control to prevent pregnancy while you are taking lorazepam.
Lorazepam can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using lorazepam.
Lorazepam is not approved for use by anyone younger than 18 years old.
The sedative effects of lorazepam may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury while you are taking lorazepam.
How should I take lorazepam?
Follow all directions on your prescription label. Never use lorazepam in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in treating your symptoms.
Lorazepam may be habit-forming. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
Misuse of habit-forming medicine can cause addiction, overdose, or death. Selling or giving away this medicine is against the law.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Lorazepam may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
What other drugs will affect lorazepam?
Taking lorazepam with other drugs that make you sleepy or slow your breathing can cause dangerous side effects or death. Ask your doctor before taking a sleeping pill, narcotic pain medicine, prescription cough medicine, a muscle relaxer, or medicine for anxiety, depression, or seizures.
Tell your doctor about all your current medicines and any you start or stop using, especially:
