If you’re feeling stuck in the pains of addiction, We Level Up Texas addiction recovery center can help you.
What Is Ativan?
Ativan is used to relieve anxiety. Ativan is in a class of medications called benzodiazepines. It works by slowing activity in the brain to allow for relaxation. Ativan is also used to treat irritable bowel syndrome, epilepsy, insomnia, and nausea and vomiting from cancer treatment and to control agitation caused by alcohol withdrawal. Ativan side effects may cause several health risks, let’s discuss how to recognize serious complications from this medication and How long does Ativan last?
How Long Does It Take To Feel Effects?
When starting Ativan, anxiety or insomnia may improve rapidly or over a period of days or within hours of the first dose of medication. Ativan tablets and liquid start to work in around 20 to 30 minutes.
How Long Does Ativan Last?
The full sedating effect of Ativan medication lasts for around 6 to 8 hours. The most common Ativan side effects include feeling sleepy (drowsy) during the daytime. It’s not recommended to use Ativan for longer than 4 weeks.
Factors That Affect Detection Time
There are a number of things that can influence How long does Ativan last. While rates usually follow a fairly consistent timeline, some people metabolize and clear the drug more quickly than others.
Some of the factors that can influence How long does Ativan last in your body include the following:
- Age: Older people tend to clear the drug more slowly than younger people. This is likely because older individuals have slower metabolisms, decreased organ function, lower blood flow, and other health issues that can affect how quickly the drug is processed and excreted.
- Kidney function: Research has found that liver impairment does not have much of an impact on Ativan clearance rates; however, kidney problems are associated with prolonged drug half-life.
- Height and weight: Taller, heavier people typically clear the drug more quickly than shorter, lighter individuals.
Dosage and Frequency of Use
How long does Ativan last? Higher doses of Ativan take longer to metabolize. The drug is also detectable for longer periods in individuals who have been taking the drug for a longer period of time.
Use of Other Substances
The concurrent use of other substances can have an impact on how quickly each is processed and excreted from the body. For example, consuming alcohol while using Ativan reduces clearance rates by 18%. Researchers believe that short-term alcohol consumption impairs the coupling of the drug or its metabolites with other molecules, which slows the metabolism process. 
How To Get Ativan Out Of Your System?
Physiological dependence on benzodiazepines such as Ativan is accompanied by a benzo withdrawal syndrome which is typically characterized by:
- Sleep Disturbance
- Increased tension and anxiety
- Panic attacks
- Hand tremor
- Difficulty in concentration
- Weight loss
- Muscular pain and stiffness
Instances are also reported within the high-dosage category of more serious developments such as seizures and psychotic reactions.
Withdrawal from a normal dosage of Ativan or any other benzodiazepine treatment can result in a number of symptomatic patterns. The most common is a short-lived “rebound” anxiety and insomnia, coming on within 1-4 days of discontinuation, depending on the half-life of the particular drug. The second pattern is the full-blown withdrawal syndrome, usually lasting 10-14 days; finally, a third pattern may represent the return of anxiety symptoms which then persist until some form of treatment is instituted. 
Physiological dependence on benzodiazepines can occur following prolonged treatment with therapeutic doses, but it is not clear what proportion of patients are likely to experience a withdrawal syndrome. It is also unknown to what extent the risk of physiological dependence is dependent upon a minimum duration of exposure or dosage of these drugs. Withdrawal phenomena appear to be more severe following withdrawal from high doses of short-acting benzodiazepines. Dependence on alcohol or other sedatives may increase the risk of benzodiazepine dependence.
Overcoming an Ativan addiction permanently involves detox and its associated withdrawal. As a benzodiazepine, Ativan is a highly addictive drug that can easily trap a person who takes it for longer than the normally prescribed four to six weeks. And once addiction sets in, withdrawal is a normal part of trying to stop.
If you are currently misusing or abusing Ativan, it is important for you to understand withdrawal and detox before you begin treatment. Note that there is no way to fully stop using Ativan until you go through the detox and withdrawal processes. Also, note that undergoing professional rehab at a private clinic offers you the safest and most comfortable detox and withdrawal possible.
If an overdose occurs call your doctor or 911. You may need urgent medical care.
Symptoms of Ativan drug overdose include confusion, impaired coordination, slow reflexes, coma, and death. A specific treatment to reverse the Ativan side effects does exist. This medicine, called flumazenil, can reverse the effects of Ativan but must be given through an IV at a hospital. Only a doctor can decide if you need this medication.

In most cases, it takes about five to six half-lives for the medicinal dose of a drug to be eliminated from an individual’s system.
