Lorazepam decreases nervous system activity, making it effective for short-term sleep issues and anxiety relief. It is often prescribed off-label for insomnia.
While lorazepam is considered safe for adults and children over 12, older patients and those with certain medical conditions, including liver or kidney disease, lung problems, and depression, should exercise caution.
Lorazepam starts working in about 30 minutes and lasts 2-3 hours. It’s usually prescribed for no more than four weeks to minimize abuse and dependence risks.
Common side effects include dizziness and muscle weakness. Long-term use or withdrawal can lead to more severe symptoms, and combining lorazepam with opioids can be dangerous.
For many, falling asleep at night isn’t always as simple as lying down and closing one’s eyes. Worries from the day may race through the mind, or getting comfortable may be impossible. Although it is normal to have trouble falling asleep and maintaining sleep occasionally, chronic insomnia can take its toll physically and mentally on one’s daily life. When relaxation techniques don’t work, many people with sleep problems look for medications to aid in the process.
While taking over-the-counter (OTC) sleep aids and supplements may help some, many times, people seek medical professional help and may be prescribed sleeping pills. Benzodiazepines, which include Valium (diazepam) and Xanax (alprazolam), are one of the most widely prescribed drug classes for the short-term treatment of insomnia. While several benzodiazepines are approved by the U.S. Food and Drug Administration (FDA) for treating insomnia, lorazepam, a benzodiazepine also known by the brand name Ativan and FDA-approved to treat anxiety, is often prescribed off-label as a sleep aid.

Lorazepam for sleep
Benzodiazepines are a class of medications that work by making the central nervous system (CNS) less active. This decrease in nervous system activity makes these medications helpful for various medical conditions, such as daytime anxiety disorders and seizures. Clinical studies have shown them to be safe and effective for the treatment of insomnia since their first approval in the 1970s. Lorazepam, approved by the FDA in 1977 under the brand name Ativan, is indicated for the short-term relief of anxiety symptoms. It is often prescribed off-label for the short-term treatment of insomnia.
Many prescription drugs are prescribed off-label to treat conditions other than those for which they were approved. Since lorazepam has calming effects similar to the benzodiazepines approved to treat insomnia, it is often considered by prescribing healthcare professionals to be an effective option. A clinical trial has also shown that lorazepam is as effective as other benzodiazepines in the short-term treatment of insomnia in trial subjects.
Who can take Lorazepam as a sleep aid?
Lorazepam is considered safe and effective for use in those 12 years of age and older, although off-label use as a sleep aid is usually reserved for adults. Those aged 65 and over may respond to lorazepam with an increase in the incidence of sedation and unsteadiness, therefore, dosing in older patients should start at lower doses and be increased cautiously.
Taking lorazepam may not be suitable for some people with any of the following medical histories or :
- Known hypersensitivity to the active drug or any ingredient
- Liver or kidney disease
- Lung disease or breathing problems (e.g., sleep apnea or COPD)
- Have depression, mood problems, or suicidal thoughts or behavior
- Have a history of drug or alcohol abuse or substance use disorder
- Are trying to get pregnant, are already pregnant, or are breastfeeding
- Have glaucoma (a condition of increased pressure within the eye)

How long does lorazepam take to work
Doses of lorazepam oral tablets are well absorbed after swallowing and will typically start to work in about 30 minutes, with peak effects lasting two to three hours. This means that lorazepam can be taken just before bedtime for most people.
Lorazepam is a federally controlled substance (Schedule IV) because it can be abused or lead to physical dependence. Because of this, it is recommended to use the lowest effective dose for the shortest period of time. It is usually prescribed for no more than four weeks at a time and is not recommended for use beyond four months. Lorazepam may be taken daily or as needed, depending on your doctor’s or other healthcare provider’s instructions.
Lorazepam dosage for sleep
For short-term treatment of insomnia, a single dose of 2 to 4 mg is taken at bedtime.
For a person over 65, the initial dose should be reduced to 0.5 to 1 mg at bedtime to achieve the desired effect. Changes to this low dose may be made as needed and tolerated.
Lorazepam alternatives
Many non-drug methods can help those who have trouble falling asleep that may be tried at home, including:
- Physical activity early in the day can improve the quality of sleep, however, avoid exercising within two hours of bedtime
- Stick to a regular sleep schedule
- Eat a healthy diet, but avoid big meals within a couple of hours of bedtime
- Avoid watching TV or using a phone or tablet right before going to bed

Lorazepam side effects and warnings
Like any medicine, lorazepam may cause side effects in some people. Some of the more common side effects when taking lorazepam for insomnia include the following symptoms:
- Dizziness
- Lightheadedness
- Unsteadiness
- Decreased ability to concentrate
- Muscle weakness
- Dry mouth
Rare but more serious side effects that may require medical help include the following symptoms:
- Shuffling walk
- Tremors or inability to sit still
- Fever
- Breathing problems
- Difficulty swallowing
- Skin rash or hives
- Yellowing of skin or eyes
- Irregular heartbeat
- Memory loss or memory problems
- Disorientation
- Sleep apnea or worsening of sleep apnea
Taking lorazepam for a long time, particularly at high doses, may result in long-term effects, usually seen as exaggerated versions of the side effects listed above.
Withdrawal from benzodiazepines, including lorazepam, can be potentially dangerous. The rate of drug withdrawal, the strength of the dose taken, and the longer use time will contribute to how severe the withdrawal symptoms might be. The most common withdrawal symptoms include a significant worsening of sleep, headaches, sweating, tremors, increased blood pressure, GI effects (e.g., nausea, cramps, vomiting), tension, irritability, anxiety, mental confusion, and even seizures in rare cases. Lorazepam should be gradually stopped under medical supervision.
Lorazepam has a black box warning, also known as a boxed warning, regarding the combined use of lorazepam and opioid medications, a class of drugs used to reduce pain. Combining the two medications can worsen adverse reactions caused by lorazepam alone and may result in medical emergencies such as profound sedation, respiratory depression, coma, and death. Following a physician’s or other healthcare professional’s medical advice, is important in order to avoid risks when combining lorazepam with another sedating drug.
