Ativan(lorazepam) 1mg how long does it last & wears off completely



New Member
Hi people, I am contemplating taking some lorazepam tablets, and thought I should check first with people who may have experience using lorazepam. I want to know how long to expect the effects of lorazepam to last for. Thank you.

It is generally accepted that lorazepam has a half life of about twelve hours. I used to take lorazepam myself for my anxiety. When I stopped lorazepam, I had lots of rebound anxiety. Missing a dose of lorazepam will cause an immediate escalating level of anxiety, according to my experience. If you manage your dosing effectively, it is possible to have round-the-clock benefit of Lorazepam. It all depends on your dosing.

I’ll tell you my own experience. That should give you at least an idea. I’ve been on Lorazepam, now for ten whole years. I only take it when I need it. Just like you, I am reluctant to take pills, in general. I start always only on the smallest dose. You would be fine with a 0.5 mg dose, and I suggest you take it at bed time. It is only going to make you feel warm and sleepy. Good luck, mate!

I got prescribed sublingual Lorazepam 0.5 mg, and was told to take one or two of them every 6 hours, as needed, but to avoid alcohol. I was wondering how quickly it starts working.

It should start working faster if you take it sublingually, than if you swallowed it with water. In fact, it starts working in about 5 minutes.

Hey there, I was prescribed Lorazepam 0.5 mg, for my anxiety. I’ve been reluctant to try it, because I am sensitive to medications, in general. Has anybody ever tried a benzodiazepine, and how did the lowest dose make you feel?

I happen to be extremely sensitive, and get the smallest dose. I have been using 0.5 mg, for some weeks now, and I can take 1 mg, if I want, but, have never needed it. All I need is 0.5 mg, and it helps me so much with my sleep. You might try 0.5 mg tonight, just before bedtime.

Hi everybody, I just got prescribed Lorazepam, and I’ve been on it for a couple of weeks now and thus want to know how long it lasts. My prescription says 1 mg twice a day, as needed. Will just one of the 1 mg tablets be enough for most of the day? What I’ve been doing is taking one tablet first thing in the morning and then one more one mg tablet in the afternoon, just to be on the safe side. The issues is, I tend to get extremely bad panic attacks, just before bedtime, and was wondering if I could save up the afternoon Lorazepam 1 mg tablet and take it in the night, to help me with the bedtime anxiety, Any advice about this would be deeply appreciated. Thank you.

When I started on Lorazepam, it started making my anxiety survivable. Now I don’t require Lorazepam as much and take it only about once in a month. From personal experience, just 0.5 mg of Lorazepam can finish off a panic attack within 15 minutes. For example, when I used to get my panic attacks, I would take a Lorazepam, and I would be pacing up and down, and I would be able to feel the exact moment, when the Lorazepam kicked in.

Lorazepam brings a wave of calm into me. It makes me feel normal within minutes, and then I can resume functioning. The only downside is the slight drowsiness, which can be great, if you are trying to sleep. It never prevented me from working, though. I managed to stop the Lorazepam, as well, without any fuss. Make sure that you keep the dosage low, and take it only when you absolutely feel that you need it. Also, try to postpone taking it, for as long as possible. I managed 3 months, and I was totally fine throughout. If you have a panic attack, however, I suggest you take it. Lorazepam is the best thing that happened to people suffering from anxiety.

The statistical information says that approximately about two hours after administration of Lorazepam, peak concentrations in plasma occur. The half-life of Lorazepam is said to be about 12 hours. This means that it takes about 12 hours for the Lorazepam in your become half of its initial amount. This half-life period of about 12 hours is relatively short, in comparison with many of the other Benzodiazepine medications.

From my own experience, which is considerably extensive, I feel the hit in about two hours’ time after having taken the Lorazepam, and the effect wears off around 6 hours after the administration. Then, need to refresh the Lorazepam, if I seek continuous relief.

The important question is, what is it you seek relief from. Is your main problem the panic attacks? Or, is your main problem all-the-time anxiety? This becomes important, when it comes to deciding when to take the second tablet. Are your panic attacks mostly at night time? In that case, you would be better off taking one tablet in the morning and the second in the night.

On the other hand, if you have a lot of afternoon anxiety, and you really need to curb that, then you would need to keep continuing the afternoon tablet. The thing is, I know nothing about you, and my intuition tells me, that perhaps, you might just be best off, taking Lorazepam three times a day, as it seems more appropriate than to need to end up compromising on a particular part of your day, in order to keep the rest of the day anxiety-free.

A serious point to consider, while dealing with medication such as Lorazepam, is the addictive potential of the drug. Still, if you need a Lorazepam, then you need it – no question about that. Always keep an eye on whether you seem to be getting addicted to the Lorazepam, and if you ever happen to feel that you may perhaps be getting addicted, you should immediately talk to your doctor. If you really need Lorazepam, then the best thing to do would be to take it. However, if you are addicted to Lorazepam, then the worst thing to do would be, again, to take it.

Have you ever considered going for some kind of counseling, to supplement your medication? Counseling can address deep-seated roots of your anxiety, and if you find a therapist with whom you are able to establish a feeling of trust and comfort, then I certainly feel that your need for Lorazepam can be reduced, and that would actually be a great thing.

Thanks a lot, my friend. Your answer was indeed helpful. Now, I have decided to take one tablet during the day and the other at night. This is what I am going to do from now on. I thought about what you said, about taking it three times a day, but I doubt my doctor is going to go down that road, considering I have had problems of Ativan abuse in the past.

The best thing to do would be to hold out, for the afternoon, which is just a few hours, as the Lorazepam from the morning wears off. The kind of anxiety I have is a combination of general anxiety and also anxiety that comes in waves. These waves of anxiety come mostly at bedtime, but occasionally during the day too. When that happens, my chest gets tight, and I get extremely afraid. I am already in psychotherapy, and I have learnt some tricks in psychotherapy, which help me deal with the anxiety. About the addictive potential, I am aware Benzos have addictive properties. That’s actually yet another thing that I need to worry about!

I'm bipolar and developed a dependency on ativan. I'm halving my dose..these should be only prescribed in crisis patients in hospital..You can get a high from a good walk or exercise..called dopamine...
Avivan is not the answer...The coming down is not worth the going up...
