Can Lidocaine Cause A Positive Drug Test
41 Replies RSS
I went to court, and took a drug screen and I was tested positive for cocaine. The day before my doctor gave me a shot that had lidocaine in it. ## From what I could gather, Caine anesthetics seem to be notorious for causing false positives for cocaine. This includes Novocaine, Benzocaine, Lidocaine, etc. If you were to take any course of action, I would recommend insisting on additional testing & perhaps requesting a GC/MS test (Gas Chromatography / Mass Spectrometry), as it is considered to be the most definitive method for confirming the presence of a drug in the urine. I think it's down right unfair for companies to not use this type of testing right off the bat, since there are so many false-positives being reported on a daily basis. At this point in time though, the best a... ...

Is there any kind of food or meditation that can cause a false positive drug test for cocaine? ## I had a hair drug test that came up positive for cocaine. I'm dealing with an addiction specialist who says that I'm a heavy user of cocaine for the last 30 days. Intetesting that I have not used cocaine. I'm wondering if anyone has had a positive hair test for cocaine and did not use and what might have happened here. Given the reputation of this dr, I went for an independent test, who also told me there was no reason to go for an independent test that it would prove nothing. I went anyway. The only thing I've used is Lidoderm patches for my back. ...

Went to dentist had tooth pulled. Dentist gave lidocaine with something else. Had a positive urine test for amphetamines. Do these do this? Or amoxicillin? I have to take antibiotic too for a while. Tooth is infected. ## No, neither the Lidocaine, nor the amoxicillin have been known to cause false positives for Amphetamines on a drug test. Learn more drug test details here. Do you know what else it was that he gave you? Could you possibly call his office and ask? ## thats a lie they can to! same happened to me when i went to have my son! and the anistesiologist even said it could be from the epidural. and amox. because i took that for a UTI and a urine test came out dirty as well. for cocaine so. bud your wrong! ## Lidocaine with epinephrine (aka adrenalin) is a common mix.

The police raided my frinds house got lidocaine claims it tested positive as cocaine in the lab is this possible cause they're looking ay 5 years in prison ## It is related to cocaine, but there is no way it should be detected as such in an actual lab test, since that type of testing would clearly be able to distinguish between the two. Are there any other questions or comments? ## I am taking a random ua for a dui and was told I tested pos. for coke. I called b.s. then remembered I had just had x-ray guided cortizone/steroid shots for my sciatica. I'm not sure what all they put in those shots but before that they used novicaine.

Urine Drug Test Lidocaine
2 Replies RSS
I am getting electrolysis twice a week for facial hair. The electrologist has been putting a topical 5% lidocaine on my face to numb the pain from the needles. I am applying for a new job and will take a urine test and wondered if this will cause a problem or show up in some way in my urine? ## It is difficult to say, it really depends on how much of it is being used and the concentration of it. It is chemically related to Cocaine, though distantly, and just like Novacaine and other similar drugs, it has been know to cause false positives for it, on some drug tests. It may be best to stop the treatments for several days, before you have the test, to possibly give your body time to process it out. Are there any other questions or comments? ## Will a 5% lidocaine patch show up on mouth sw... ...

I have a small delivery/transportation business in Ohio. My husband & I decided to grow our company by purchasing a vehicle that requires a CDL B. The guy we have driving that truck has his class A but if he quit or needed a day off we had no one to fill in so I took classes to get my CDL A's in March of 2014. After receiving my CDL’s [for experience & financial reasons] I made the decision to sign on & drive for a large trucking company in June of 2014. The company performed a hair drug test on me but apparently did not get they're results until after I started the orientation. During my orientation the MRO called & tells me that I tested positive for cocaine. I knew that there had been a mistake because I am not a drug user. He asked me had I been to the ... ...

Can Lidocaine Shots Every Month Test Positive For Cocaine
1 Reply RSS
I have been getting lidocaine shots in my back every month for 4 yrs and lidocaine infusion. every 3 months would that show as cocaine on a drug stick test ## Hi J, Other than a few forum posts from different individuals, I haven't located any concrete details confirming the possibility of a false positive for Cocaine from Lidocaine. However, I do have reason to believe that it's still a strong possibility due to the faulty standard drug tests they use today. A lot of these standardized drug tests have a fairly high false-positive response, where it seems as though anything is likely to show up, no matter what you took. To my knowledge false positives are known to occur on them anywhere from 4 to 50% of the time. Have you asked your doctor yet about getting re-tested? ...

can lidocaine used for mouth ulcers cause a false positive for cocaine in a urine test
1 Reply RSS
I tested positive for cocaine but use liquid lidocaine for mouth ulcers every 4-6 hours and have for months. ## I realize this question was posted a very long time ago but I wanted to let you know that viscous lidocaine, which is what you are referring to and I was recently prescribed, will not cause a positive result for cocaine. It does however sometimes cause a positive result for one of the amphetamine categories (I believe it was methamphetamines). According to poison control and to the lab that I spoke to the only thing that can cause a cocaine positive on a drug test is actually cocaine. Not lidocaine or novocaine or bupivacaine, etc. ...

i need to know if lidocaine viscous can show up as alcohol in a urine test. ## can lidocaine show up as cocaine on i urine test i got a friend that failed a drug test for cocaine but he said he dont do that he said he used lidocaine for a toothache i need to know asap ## On the alcohol question, no it should not show up as that, however, if you have a prescription for it, you should inform them of this, when you go in for testing. Which leads to pnut's question and yes, it can cause a false positive for Cocaine on some tests. It is distantly related to it. Since this works as an anesthetic, there can be severe problems associated with using it improperly and overdosing, so it shouldn't be used with a doctor's instructions and supervision. Are there any other comments or ques... ...
