Generic Name: lorazepam

What is Ativan?

Ativan (Generic Name: lorazepam) is a benzodiazepine primarily used for short-term relief of symptoms of anxiety disorders in adolescents and adults. It may help relieve excessive worry, shortness of breath or heavy perspiration, feelings of edginess, and difficulty sleeping due to anxiety. The safety and effectiveness of taking lorazepam for more than four months in unknown.

Ativan is also used off-label to treat alcohol withdrawal, insomnia, and to prevent nausea from chemotherapy.

How to Use Ativan

Before starting or refilling an Ativan prescription, read the medication guide included with your pills, as it may be updated with new information.

This guide should not replace a conversation with your doctor, who has a holistic view of your or your child’s medical history, other diagnoses, and other prescriptions. If you have questions, ask your doctor or pharmacist before you begin taking the medication.

Dosage for Ativan

As with all medications, follow your Ativan prescription instructions exactly. Lorazepam is taken orally with water or another liquid, with or without food.

Do not drink alcohol while taking this medication.

The dosage varies by the condition treated and by the patient’s health. A typical schedule is divided into two doses per day. The highest dose is given before bed when the potential reaction of sleepiness is less disruptive. Your doctor may increase your dosage gradually over time to decrease the potential for side effects.

Doctors may recommend starting with a lower dosage for elderly patients or patients with advanced liver or another debilitating disease who may be particularly sensitive to benzodiazepines.

When discontinuing treatment, or decreasing dosage, patients should work with a doctor to gradually taper the level of medication. Stopping lorazepam suddenly can create withdrawal symptoms, and seizures can occur.

Some patients develop a tolerance to lorazepam. Do not increase your dosage without discussing it with your doctor. Your doctor should periodically reassess whether the treatment is still useful. Long-term treatment with lorazepam increases the risk of dependence and may cause difficulty when terminating treatment. After an extended period without symptoms, a patient may work with his or her doctor to taper off the medication gradually.

For updated information about dosages, interactions, and precautions, see the Ativan drug monograph on WebMD.

Side Effects Associated with Ativan

The most common side effects of lorazepam are similar to those associated with Alprazolam and other benzodiazepines, and are as follows: drowsiness, dizziness, weakness, unsteadiness, and symptoms of dependence/withdrawal with long-term usage.

Other serious side effects include constipation, depressive thoughts, loss of appetite, sexual problems, jaundice, memory impairment, headache, and blurred vision. If you stop taking lorazepam suddenly, a life-threatening seizure can occur.

In rare cases, lorazepam can have the opposite of the desired effect — called a paradoxical reaction —and increase anxiety, aggression, insomnia, or agitation. This effect is more common in children and the elderly.

Taking lorazepam may impair your ability to drive, operate machinery, or perform other potentially dangerous tasks. This side effect usually wears off with time. If side effects are bothersome, or do not go away, talk to your doctor.

Most people taking this medication do not experience any of these side effects.

Disclose to your physician all mental health issues including any family history of suicide or depression. Lorazepam may create new or exacerbate existing behavior or mental problems. Call your doctor immediately if you or your child experiences new or worsening mental health symptoms including hallucinations or changes in mood.

Lorazepam can cause kidney or liver problems. Elderly or debilitated patients with impaired renal, hepatic, or pulmonary function should use caution and be observed closely when taking lorazepam. Seek medical help right away if you experience yellowing eyes or skin, seizures, or signs of an allergic reaction.

Benzodiazepines like lorazepam have a low potential for abuse and addiction among people who have anxiety. It is a “Schedule IV Stimulant,” a designation that the Drug Enforcement Agency uses for drugs with a low potential for abuse. Other Schedule IV drugs include Valium, Alprazolam, and Ambien. However, long-term treatment in higher dosages with lorazepam increases the risk of dependence, especially for people with a history of substance abuse. Taking the medication exactly as prescribed can reduce potential for abuse.

The above is not a complete list of potential side effects. If you notice any health changes not listed above, discuss them with your doctor or pharmacist.

Precautions Associated with Ativan

Store Ativan in a secure place out of reach of children, and at room temperature.

You should not take lorazepam if you are sensitive to benzodiazepines, or have acute narrow angle glaucoma.
