Lorazepam

Ativan™

What It's For & How To Take

Lorazepam acts on the brain and nerves in the brain to produce a calming effect. It does this by enhancing a chemical in the brain which decreases excitement.

Lorazepam is used to treat anxiety, short-term treatment of insomnia, and chemotherapy-related nausea and vomiting. Lorazepam is usually a tablet that is swallowed. However, it will dissolve under the tongue when someone is unable to swallow the tablet.

Lorazepam is usually prescribed to be taken not more than three times daily. Your doctor will adjust your dose based on your response to treatment. This medication may be taken with or without food.

If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Do not increase your dose of lorazepam or take it more often than ordered without your doctor’s approval because this drug can be habit-forming.

If you have taken this medication for a long time, you may notice that it doesn’t seem to work as well. Contact your doctor to discuss the options. If you have taken this medication for a long time or in a high dose, do not stop taking it all at once because it may cause a withdrawal reaction. Your doctor may have you decrease your dose of lorazepam over a couple weeks or months.
