Yes, Lidocaine is actually related to Cocaine and it has been known to cause false positives for it, in people that are using it regularly.


Learn more Lidocaine details here.

There are also other medications that may cause it. What else do you take?

I just had a baby on September 15th and had to have an emergency c-section, which they filled me with so much drugs in my epidural that my hands and also my head were numb as well. I went to the emergency room yesterday b/c I have been recently put on a lot of new medications, that are for my UTI , lexapro for my depression, a mood stabilizer depacoat, and Klophon for anxiety plus I have been taking Suboxone for 1 1/2 or 2 years, I was falling asleep when in active even when just standing up. It was scary well they took my blood and urine sample and it came back in my urine that I had cocaine in it and i have never touched the stuff. What could cause this? My mom was with me and now thinks I am a drug addict and it breaks my heart. I really need help. Could I have been from the epidural??

I do not do drugs. I have two children and they could get taken away from me over something I did not even do.

I had some pretty serious dental work done the day before an appointment with my pain Doctor. Since he prescribes pain meds for me monthly, I am usually asked to UA as I was this time. I have been surfing your website and now am concerned that the lidocaine I was given could cause me to test positive for cocaine. Is that possible and if it is, what should I do?

Honey, I came up positive for cocaine from a root canal and crown. The company swears that the tests know the difference but they don't. UA can not differentiate from one caine to the next. Cocaine, Lidocaine, Novocaine. etc. the idiots running this country have turned a blind eye to drug traffickers from other countries. Instead we hunt down honest patients who are playing by the rules. Contracts with our doctors so we can be persecuted. The reason the drug epidemic is so big in the US? They've made it so hard to play by the rules, one is forced to go to the streets. If I was being threatened about my kids, I'd DEMAND they test my hair to prove I was not doing drugs. This test is pricey but more accurate than urine and goes back further in time. What price do you put on keeping your kids? It's insane.

An ER drug screen has my friend as positive for cocaine and amphetamines. He doesn't do either drug. He had Lidocaine injections two days before this 12 of them down his back and he used cream with Baclofen, Bupivacaine, Cyclobenzaprine, Diclofenac, Gabapentin, Ketamine and Lidocaine. He uses said cream from his neck to end of spine several times a day. The night before his ER visit he also laid in a tanning bed a couple of hours after applying the cream. Could any of this caused him to test positive for the cocaine and amphetamines? If you have any references for your answers please I would like them too.

The more I read the more I see many people that have had the same situation as I. False positives for cocaine as the have used lidocaine 5% patches. I need someting in writing that would hold in court so I can prove that is possible for what took place in my situation. I take random UA's, 5 or more per month and I 100% do not use cocaine . I need help so I can get my daughter back in my life without being subject to paid supervised visits and also want my reputation cleared for I am not using illicit drugs. I used only the medications I am percribed correctly. Please direct me to any help possible to get to the bottom of this. Thank you kindly, Ryan

Hi Falsely Accused,

There has to be a connection between lidocaine & cocaine because there are several people that this has happened to. I am not a drug user and rarely even drink alcohol but tested positive for cocaine in a hair drug test from my employer. So, to prove them wrong, I went to a different lab and paid for a hair drug test myself and it came up positive again. 3 months prior to the drug test I had been injected with lidocaine several times for a biopsy. I had also had a tooth pulled and developed 'dry socket' and they gave me petroleum based Xylocaine to keep putting in the dry socket until it began to heal. However, I was told by 3 different doctors that Lidocaine will not show up as cocaine because they are not related in any way. There has to be something that can be done about this. Too many (non drug user's) are losing jobs and reputations because of this. If you find out any thing that can help, please post it here. And I will do the same. Thank you!

I tested positive for cocaine on a hair follicle test. I have not used cocaine but, I had a baby 12 days ago. I was given a epidural. Could that cause me to test positive for cocaine?

Oc 80 6 times a day and perc 30 5 times a day?! You're lucky to be alive. Your doctor is dumb and shouldn't be prescribing medicine to people.

Yes it happens a lot after dental surgery and you could get something in writing from your dentist acknowledging the ingredients you were administered and their possible false/positive metabulites being related to a positive cocaine result. As protection or as evidence for your attorney if the future ruins your life as many others were in the year 2016.

Ummm of you're taking suboxone you are a drug addict dear. Means you had a serious problem with pain pills or heroin, same thing. Suboxone is prescribed for the same thing as methadone, for getting/staying off opiates. Suboxone contains 2 chemicals, buprenorphine and naloxone. Buprenormphine by itself is known to be a pretty good pain killer. But naloxone IS an opiate blocker which no dr would prescribe you unless you were an addict. They would have given u subutex (which is buprenorphine without the naloxone) . Step 1 in the 12 step program is admitting ur an addict.

Hi, please help. I am in the same situation and need support. I had surgery, and lidocaine was used. I failed a drug test for cocaine; my test involved an injection into my bloodstream. I have been denied a great job.

Laura - YES LIDOCAINE CAN cause a false positive...ALL THESE POSTS are making me so mad! I will tell you this- I KNEW a LAB WORKER who came across a RELATIVE'S urine sample. They knew this relative was a heavy cocaine user. What do you think she did? She simply swapped the urine sample with another male's clean sample. We are in a country that THIS KIND OF CRIMINAL MESS is rampant and SO SO EASY to do. I do not "know" that person anymore . I have medical issues and it infuriated me.And IF I DIDN'T HAVE MEDICAL ISSUES, YES, IT WOULD STILL INFURIATE ME. I, anonymously, told "authorities" about this and was laughed at. So I sent a letter to the lab that was typed, and reported it. 3 years later and she's still working there. The people that work in these "labs" are just THAT..PEOPLE. And people do stupid $%@#!!! So SORRY for your nightmare. It is so screwed up...UGH.

On April 13,17 I had to have an emergency c-section in order to give birth to my beautiful baby girl. Where the doctor filled me up with a lot of epidurals that numb me from head to toe for hours. The nurses had to watch me closely til the feeling came back into my legs and body. After I gained feeling back in my body the nurses brought me my baby to feed. I stayed in the hospital til the doctor released us on the 15th of April. Before we could be released from the hospital the staff called Dcf on me. And I had to leave without my baby girl til I got word from the courthouse. Once I found out my court date I had to take a drug test on May 1st, 2017 which came back positive for oxycodone. But I was taking pain medicine that was prescribed by my doctor yet the state wouldn't accept it in court. And I still had to go through numerous tests which I passed, but my hair still came up positive for cocaine and benzocaine which I DON'T do. Please please I need some questions to be answered in order to help me with my case to fight against the state so I can get my children back home.

I hate to say this, but people use Lidocaine to make Cocaine, hence why when you touch Cocaine to your tongue it gets numb. But this is actually common sense ;)

I know this is an old post but my situation is identical. Every bit down to not seeing my baby. I've taken about 50 and even ask for them to prove the lies but nope. 1st positive...cocaine. NO WAY. I have lupus and use Lidocaine Hydrochloride gel. So many antibiotics..and meds, all new. I finally was able to afford to go back to court as a fighter who survived, to get smashed...

Yes that's why.. I'm currently fighting for custody of my daughter. She was born a preemie. After I gave birth I tested positive for cocaine and I never used it.. Also my my case worker doesn't believe it either but she's still not on my side. It's best you get a list of all meds you were given while in the hospital. I'd get a nurse to write affidavit.. Might need a lawyer. I had to get one.
