Ativan is the brand name for lorazepam. Typically, this drug is prescribed for anxiety disorders and depression. However, it can also be used as a sedative for epilepsy.
When taken according to the prescription, Ativan is a safe drug. It can become dangerous if it is taken with other drugs or alcohol. Because it is a sedative, it can slow your breathing and potentially become fatal if it is used incorrectly.
If you are using Ativan recreationally, it is important to seek professional medical advice as you try to recover. In an addiction treatment program, you can get professional supervision and support as you recover. To learn more about the duration of Ativan’s effects and its effect on your body, read on.
What Is Ativan?
Ativan is considered a benzodiazepine. Benzos make up a class of drugs that depress the central nervous system. It is because of this effect that Ativan is able to treat seizures, anxiety, and short-term insomnia.
Besides treating anxiety, Ativan is often used to alleviate the nausea and vomiting that occur during cancer treatment. Additionally, it can be prescribed during alcohol detox to reduce withdrawal symptoms.
Ativan functions in the body by slowing down your brain and nerve activity. This is why it can make users feel calm and relaxed. When used at different doses, it can stop muscle spasms and seizures.
How Long Does Ativan Last?
The half-life of any drug is the time it takes for the total amount to be reduced by half. Each drug has a different half-life. Additionally, the half-life can vary based on your metabolism and unique body chemistry. To understand how long Ativan lasts, it’s important to gain a basic understanding of the drug’s half-life in the human body.
Ativan Detection Times for Drug Tests
Ativan (lorazepam) is a benzodiazepine used to treat anxiety, seizures, and insomnia. Its detection time varies based on the test type, metabolism, dosage, and frequency of use.
| Test Type | Detection Window | Notes |
| Urine Tests | Up to 6 days (single use), Up to 9+ days (chronic use) | Most common drug test for benzodiazepines |
| Blood Tests | Up to 24 hours | Detects recent use, not long-term use |
| Saliva Tests | Up to 8 hours | Short detection time; rarely used for benzos |
| Hair Follicle Tests | Up to 90 days | Detects long-term use, but less commonly used for Ativan |
If you’re facing a drug test, it’s important to note that Ativan and other benzodiazepines may be detected longer in chronic users due to accumulation in fat stores.
Half-Life of Ativan
Ativan, a prescription drug and controlled substance classified as a schedule IV drug, has a half-life of 14 hours. Depending on the amount of time consumed and other factors, this half-life can vary by up to five hours. Because most drugs are fully eliminated after four to five half-lives, you can generally expect Ativan levels to be close to zero after 56 to 70 hours, meaning it will be completely out of a person’s system within that time.
There are a few important caveats to keep in mind. If someone has a substance use disorder related to Ativan, it may take longer to eliminate the drug. People who suffer from drug use often have a tolerance to Ativan, so they use a larger amount of this drug. In turn, the higher amounts mean that Ativan takes more time to be fully eliminated from the body. This is because the body has to process a larger amount of the substance.
When the body metabolizes Ativan, which affects the peak effects of the drug, it occurs primarily in the liver. Then, the drug is fully eliminated through the kidneys and urine. Because of how it is metabolized, there are some metabolites that may remain for longer than a week. However, the actual drug compound is generally eliminated in three days or less after the last dose. Ativan works by enhancing the effects of GABA (gamma-aminobutyric acid) in the brain.
Sometimes, people want to know about Ativan’s half-life because they are trying to pass a drug test. Ativan will normally stop appearing on urine tests after just three days. Hair tests can still detect it up to 30 days later after ingestion.
The Duration of Effects
Ativan’s effects generally last for four to six hours. However, people who are especially sensitive to the drug’s side effects may feel sedated for a little longer. The main effects will generally start to subside after the six-hour mark.
If you abuse Ativan, this timeline can vary. When someone has an Ativan addiction, the drug’s effects may go away after just one or two hours. Additionally, they will likely need higher doses in order to achieve the same effects.
A drug’s half-life and the duration of its effects aren’t the same thing, which is why these figures are so different. The effects of Ativan typically end significantly before the half-life is reached. While the half-life represents how much of the drug is present in the body, the duration of its effects simply represents how long you will be able to feel Ativan’s side effects.
Factors Influencing How Long Ativan Lasts
While the previous figures are normally how long the effects and half-life last, individual results can vary. There are several important factors that can contribute to how long Ativan lasts in the human body. In addition to the dosage and your substance abuse history, your liver function, age, dosage, kidney function, and the presence of other medications can also impact the drug’s efficacy.
- Age: The individual’s age can impact how long it takes for the body to process Ativan. In general, older adults process this drug at a slower rate, which causes the effects to last longer. In addition, older adults are more likely to experience more intensive side effects.
- Dosage & Frequency: In general, a higher dosage leads to longer-lasting effects.
- Liver and Kidney Function: Ativan is typically metabolized by the liver and kidneys. Because of this, impaired kidney and liver function can affect how well your body metabolizes drugs. If you can’t metabolize the drug properly, it will remain in your body for longer periods of time.
- Metabolism: Each person has a unique metabolism rate. If your body metabolizes drugs slower or faster, it will impact how you experience the effects and how long Ativan lasts in your body.
- Additional Medications: Sometimes, other medications can interfere with Ativan’s effects. For instance, certain medications may cause Ativan to be eliminated at a faster or slower rate. Because of how dangerous some drug interactions can be, it’s important to always consult with a doctor before you take other medications when you are already taking Ativan.
- Usage History: If someone engages in long-term use of Ativan, they may develop a tolerance. Because of this, the same dose will cause less of an effect. The amount of time someone uses Ativan can greatly affect the development of a tolerance.
- Hydration & Activity Levels: Hydration and exercise can slightly affect clearance.
Important Considerations
When taking Ativan for your physical or mental health, there are a few important things to keep in mind. The following list includes a few examples of things you should talk to your doctor about before starting or discontinuing Ativan.
Tolerance and Dependence
If you take medications for an extended period of time, it can lead to drug dependence and a higher tolerance. Tolerance is when you need more of the drug to achieve the same effects. Meanwhile, dependence means your body feels like it needs the drug to function properly. If you are dependent on the drug, you will experience withdrawal symptoms if you stop using it suddenly.
Normally, Ativan is only prescribed for short-term use. If you take it for a longer period of time, it can end up leading to drug dependence and tolerance. Because withdrawal side effects can be incredibly uncomfortable, it’s important to reach out for professional medical help when you start the detox process.
Side Effects of Ativan

Safety Precautions
To ensure the safety of yourself and others, you should never drive or operate heavy machinery while using Ativan. This drug can impair your coordination and cognitive function, which can make driving dangerous. Similarly, you should never use alcohol and other drugs while taking Ativan because this can cause life-threatening complications. This is especially true if you use Ativan at the same time as other central nervous system depressants.
Finally, you should never use Ativan while pregnant or breastfeeding. Instead, talk to your doctor to find out if the benefits of taking Ativan outweigh the risks. You should also consult with a medical professional about your Ativan use if you plan on becoming pregnant.
