Clonazepam - What would make Klonopin not show up on a drug screen?

I was hospitalized the day before Easter. When I got out my therapist called and said that my klonopin wasn't in my system and that they had to take me off of it. I take it everyday 1mg 3x daily. This is unbelievable. I'm gathering as much info as I can on the subject and throw it in there face for not believing me when I said I take my medication. This is absolutely disgusting and they should know better. They didn't even taper me off, just straight up took it away because "it wasn't in my system so you don't have to worry about withdrawals/seizures!". So pissed.

I started drinking green tea. A month later had drug screen, and Klonopin did not show. I stopped drinking green tea, and it showed up. By the way, in March of last year, I was taken off Klonopin. Vomited, no sleep, lost 40 lbs, nightmares, and auditory hallucinations for months. Now, I am jerking and have been put on Ativan. Doctors don't know what they are doing.

Hello.
This medicine is amongst a group of meds that needs to be targeted to find it. A standard screening likely won't be looking for this. Reasons vary. They never found it in my brother's spot tests when he was an over-the-road truck driver for 30 years.

Clonazepam will never show up in a standard test for urine. It has to be analyzed in a lab, and even then, 7-aminoclonazepam is still hard to detect. I get tested weekly and take 4 mg a day, but the lab will find it when it's sent out for analysis I can't believe how many doctors are oblivious to the facts and rely on their laurels thank God mine knows better.

"Klonopin (clonazepam) isn’t like any other benzodiazepine. It’s the only one that’s broken down into the metabolite known as 7-aminoclonazepam (7AC). This means it does not show up in many standard drug tests, such as the SAMHSA-5. Labs must specifically screen for Klonopin or its metabolite."

I can think of three reasons why Clonazepam (or any drug) might not show up on a drug screen:

1. The dosage was too low.
2. Too much time passed since the drug was taken, so it was mostly out of the person's system.
3. The drug was not included in the list of drugs being screened.
4. The lab is incompetent.

I'm also on Klonopin, I notice if I drink a lot of water it will not show up in my system, yet the Dr says it should be in my system up to a month. I video tape myself taking it. But they only care about the urine test. Someone above said to file a grievance, can I ask how this works ? Who do I file it with, because I take my pills, I do not understand why they are not showing up. I can use some help please.

I have taken clonazepam for 10+ years and it never shows up on urine tests for me either. I always thought it was due to other medications I take that could possibly mask it. If you request they test your pee and send it into the lab they can detect minor traces in it I have found as well. Weird though.

Research has shown that this is true. It has to do with how klonopin is metabolized. Even in a lab, it might not show up it they use GC/MS testing. For some reason there are people who continue to maintain that there is not reason for it. They are misinformed, or under informed. "It does not react well by the commercially available screening reagents" If you want more detailed information, please look up research by Dr. Peter Abaci, as well as many others!

You have to look for it to find it.

It would stay in my system for 3 days. Every time I'd pass. I guess it depends on your metabolism...

Will vinegar cover up Klonopin in a ua? What will really cover it?

There's a hundred different answers here. Klonopin has a longer half-life than Xanax. But does not always show up on UAs. Don't know why, and you don't know when it will or won't. But it sometimes doesn't. Maybe depends on water intake, other drugs, kidney functions or liver functions for that period, metabolism, who knows. But in my case, it would show up sometimes, sometimes not. Same dose, same times, just did what it wanted. To be sure it's out, if you take it once or twice, give yourself 5-6 days, and hydrate yourself just in case.
