How long does ativan (lorazepam) stay in your system?

6 to 8 hours active: Ativan (lorazepam) is a mid range benzodiazepine with an active period of 6-8 hours of sedation. After 6-8 hours, Ativan passes again through the liver. Now the liver breaks the Ativan into 2 parts- each part has no psycho-active effects. Lower dosages are used for geriatric adults and medically debilitated patients. Their bodies are slower to metabolize Ativan into its 2 inactive parts. ...Read more

I'm on. 5 mg of ativan (lorazepam) daily. Can I just go off it? Also how long does it stay in my system if I wanted to have a drink? Been on it for a year.

Do NOT stop w/o Doc: It is usually recommended not to use this drug for longer than 4 months without clear reasons. It is always recommended that the drug be tapered with the help of a physician. Ask that physician to tell you when you might be safe to have any alcohol. The risk seems to be that the combo will be dangerously much stronger. So, if & when you do drink - have very low proof & a very small amount. Best! ...Read more

I just took my first dose of ativan (lorazepam). 1/2 of a. 5 mg tab and I feel hyper. Is this normal? How long is it in my system? Will I be able to sleep?

Paradoxical response: This is not an uncommon phenomena. I would note your response to benzodiazepines, and not take them anymore. If you can't sleep tonight try a little over the counter Benadryl (diphenhydramine). ...Read more

I took 3 20mg tablets of prednisone ended up in the er about 2 hrs after (im allergic) gave 2 shots benadryl (diphenhydramine) & ativan how long til Pred. Out of system?

Unlikely allergic: I presume your reactions were from the prednisone which may cause hyperactivity, depression, anxiety, insomnia, palpitation, flushing occasionally in a few people when given at this dose. I would expect these side effects to decline after about a day and subside altogether in 2-3 days. The problem may also be from the disease for which the prednisone was prescribed. Not allergic ...Read more

I took 2 mg of Ativan (lorazepam) at 7 pm yesterday. I was wondering if it would be ok for me to have a few drinks at 2pm today. Will it be out my system?

Ativan (lorazepam): Two mgs of ativan (lorazepam) is a strong dose and it's effect may be dissipated after 12 hours but there is some possibility that there may be some interaction with alcohol after 17 hours if you're a slow metabolizer. If you feel any residual effect of the medication, Don't drink alcohol especially if you're going to drive. ...Read more

I have had two urine screens, both did not show any benzos in my system but I take 1 mg. Ativan every night for the past two months. Any insight?

Unreliable: I personally feel that these urine drug screens leave a lot to be desired. If you had the screen done in the afternoon or evening, and you take it at night, it may have been out of your system. Did you get in trouble because it wasn't in your system? ...Read more

Since I switched from ativan (lorazepam) 6mg back to clonazepam 2mg I don't have to take 2mg somedays just. 5mg is because of the ativan (lorazepam) leaving my system?

Since I switched from ativan (lorazepam) 6mg back to clonazepam 2mg I don't have to take 2mg somedays just. 5mg is because of the ativan (lorazepam) leaving my system?

Klonopin (clonazepam) is more: Potent than ativan, (lorazepam) and this varies a great deal between people. However, if you have a history of seizures, and you are on a significant dose of benzodiazepines, sudden reductions may increase the chance of having more seizures. There are better ways to treat anxiety over the long haul than using benzos - psychotherapy (esp cognitive behavioral therapy or cbt), antidepressants and other meds. ...Read more

My drug screen results were negative, why? I take percocet and ativan (lorazepam) on a daily basis, my screen results did not find them in my system. Knowing that I take my meds daily, I cannot understand why they did not show.

My drug screen results were negative, why? I take percocet and ativan (lorazepam) on a daily basis, my screen results did not find them in my system. Knowing that I take my meds daily, I cannot understand why they did not show.

Many possiblereasons: Oxycodone may not show up on a drug screen unless the screen is specifically geared to that drug. Ativan (lorazepam) should show up, but it depends on the dose. If you are on a low dose (0.5 mg a day) it may be negative. Also, if you are drinking large amounts of water, it dilutes your urine to where drugs may be below the detection limit of the test. ...Read more

Hopefully, 60+ yrs: I'm thinking that you might have a part of you that wants another chance. This was an action that certainly is serious and may have done some significant damage - but it is not a drug that is reliable for ending life. Please don't take more - it may just do more harm. Please call a suicide help line - it's confidential and can really help you get through this hard time. ...Read more

I was on ativan (lorazepam) 6 mg for 15 days how long will the half life last I heard only a day or two?

More Information?: Please re-ask this question with some context on why you are asking. There is nothing about the half life of benzodiazepine medications on their own. If you are asking about testing then the average urine screening for benzos can easily pick these up for six weeks after the last use, regardless of the 'half life' of the medication. ...Read more

My Ativan (lorazepam) is as needed. 5 3x a day, Can I take two at one time? As long as I don't take more then 3 in one day.

Great Question: The truth is that you CAN take two at a time. The real question is SHOULD you? Ativan (lorazepam) is a short-acting anti-anxiety medication that is very effective. When the effect wears off, patients are inclined to take more. This sets the stage for over-use, misuse and possibly abuse. Talk to your doctor before altering your medication dose or schedule. There are many options to managing your symptoms. ...Read more

I was taking ativan (lorazepam) 3mg at bedtime for 6 weeks and stopped jan 23rd and still feel aweful. How long does this last?

Not sure what it is.: You don't say why you were taking the Ativan (lorazepam) or how you now feel awful. The Ativan (lorazepam) itself is long ago out of your system, so it's not causing the problem. Did you have a return of whatever symptom you had before, e.g., not being able to get to sleep? Do you feel bad in a new way? Assuming a doctor prescribed the ativan, (lorazepam) speak with him/her about what's happened; no need to continue to suffer. ...Read more

How long till ativan (lorazepam) leaves the body for 2.5 weeks I've been taking anywhere from 1.5 mg to 1 and have not taken any since Wednesday?

Half-life: To be conservative always use the top end of half-life ranges. Ativan's is 20hrs to have only half your last dose in your system. So, after approx a day you'd have less than 1 mg in you. After 2 days, . 5 -- 3 days, . 25 -- 4 days, . 125. It should be totally gone by a week. It may be less - but I'm being conservative. Best! ...Read more
