1 mg lorazepam (ativan) is equal to 0.5 clonazepam (klonopin). Klonopin has a half life of 18 hrs up to 50 hrs whereas ativan has a half life of 10 hrs up to 20 hrs.

So how many green k-pins are in 2mg Ativan?

HOW can you say that a 1mg ativan is equal to a 0.5 mg,just because t shelf life?I agree klonopins last longer,but that doesn't mean that there isn't the same amount of lorazepam in the ativan as there is clonazepam kolonopin?I'm just wondering where the information is coming from?I'm trying to figure that out myself,because you can't just say there's more medication in the klonopin because of the shelf life.

Honestly for me klonopins do not work I'd rather take .5 mg of ativan over and mg of klonopins ... I've just been prescribed klonopins after being on ativan and once again I'm suffering from anxiety but everyone's different I have generalized anxiety disorder (GAD) and panic disorder so maybe that's why it doesn't work for me I don't know...

Unlike Klonopin, Ativan has very low lipid solubility. This causes it to stay in the vascular compartment. As a result, you will experience peak effects from Ativan for 6-12 hours. Ativan's elimation half life is 9-20 hrs. Klonopin has a longer half life at 50 hrs. but with its high lipid solubility, it quickly breaks the blood-brain barrier, and peak effects are closer to only 1-2 hrs. The two agents are more or less "cousins" & one being stronger than the other may not mean it will work better. For further info, reasearch the pharmacokinetics of each agent.

I would like to know which gives you the best result ativan or klonopin

Depends on your type / level of anxiety. Ativan is more for calming your system down immediately, while Klonopin will keep you calm through out day. I have been on both , & from personal experience klonopin is more a stable medication. But if you let it dissolve under your tongue it will give you restless like ativan but continue longer if needed. If you suffer from sudden attacks here and there ativan is your choice. If you suffer constant anxiety I believe klonopin is a better option.

1mg of clonazepam is like a 2.5mg Ativan. And clonazepam is longer lasting.

No I think klonopin 1mg is much higher than 1 mg of Ativan free discount card
