Ativan
® (
lorazepam) is a prescription medication that is used to treat
anxiety. An injectable form of the medicine is also available. The injectable form of the drug is used to decrease nervous tension and anxiety, as well as treat severe
seizures (known medically as
status epilepticus). Ativan is part of a group of medications called benzodiazepines.

Ativan is part of a group of medicines called benzodiazepines.
These medications have several effects on the body, including:
- Reducing anxiety
- Causing sleepiness
- Relaxing muscles
- Stopping seizures
- Impairing short-term memory.
All medicines in this category can have these effects to some degree, depending on the specific benzodiazepine that is being taken. They work in the brain by enhancing the effects of
gamma-aminobutyric acid (
GABA), a brain chemical that is naturally calming. GABA can slow down or stop certain nerve signals in the brain. This is why Ativan and other benzodiazepines are known as mild tranquilizers, sedatives, or central nervous system depressants (CNS depressants).
When and How to Take Ativan
Some general considerations for when and how to take the medication include:
- It comes in tablet, oral liquid, and injectable forms. When used orally, it is usually taken two or three times a day (or sometimes just before bedtime).
- It can be taken with or without food. If it bothers your stomach, try taking it with food.
- For the medication to work properly, it must be taken as prescribed. Ativan may cause serious problems if you take it at higher dosages or for a longer period of time than your healthcare provider recommends.
The dosage that your healthcare provider recommends will vary depending on a number of factors, including:
- Your age
- Other medications you may be taking
- Other medical conditions you may have.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
As with any medicine, side effects are possible. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Common side effects include, but are not limited to:
- A sleeping or calming effect (known medically as sedation)
- Dizziness
- Weakness
- Unsteadiness.
