Lorazepam (Ativan)

Lorazepam is a benzodiazepine, sold as Ativan, used for anxiety. Like others in its class, it's meant mainly for short-term or occasional use.

Also known as: Ativan

What the word means

Lorazepam is the drug. Ativan is the brand.

It’s a benzodiazepine, and it sits in the middle of the class in terms of how long it lasts. Longer than alprazolam, shorter than clonazepam. It’s used for anxiety, and it turns up frequently in hospitals and emergency settings, partly because it can be given by injection.

The cautions are the class cautions, and they’re real. Regular use brings tolerance and physical dependence, and stopping abruptly can cause dangerous withdrawal. It’s a controlled substance.

When to seek professional care

Never stop a benzodiazepine abruptly on your own, because withdrawal from this class can cause seizures and can be life-threatening. Don’t combine it with alcohol or opioids, which is where most serious harm from these drugs happens. If you’re taking more than prescribed or can’t cut back, tell a clinician directly. If you have thoughts of harming yourself, get help right away by calling 911, or call or text 988 in the US to reach the Suicide and Crisis Lifeline.
