Subj: Albuterol inhaler
Date: 4/8/2007
I NEED to know if an overuse of albuterol could cause a false positive. I was 6 weeks from graduation from Drug Court I developed a bad bacterial infection in my sinuses and lungs. I used my inhaler probably 6 to 10 times a day. I was prescribed augmentin. while at the doctor’s office I voiced my concerns that I might have a kidney problem. The following Monday I had a false positive drug screen. I’ve been in Drug Court for almost 2 years, once before the same thing happened, at that time I used my inhaler the same way I also had a yeast infection. I was put back in Phase one, 3 days in jail and I have to start all over again. I did not use drugs, I have 16 months and 2 days clean and am facing prison for this…I need to Know for ME Please tell me what you think?


AskDocWeb: The chemical name for albuterol sulfate is (alpha) 1 [(tert-butylamino) methyl]-4-hydroxy-m-xylene-(alpha), (alpha)’-diol sulfate (2:1) (salt). It may be possible that the meth part of that is showing up in your drug test.

Subj: Freaking out
Date: 4/9/2007
I tested on March 12,and they called 3 weeks later and said that I was positive for THC. I haven’t smoked since July of 06. The lady that was tested just after me was dirty with THC. I am freaking out. Is there any way that the THC could be in my system since July?


AskDocWeb: Not unless they did a hair sample, then it could.

Subj: False Positive?
Date: 4/10/2007
I have a relative who tested positive by GC/MS for steroids. He was taking supplements for body building One being Hemadrol and the other propadrol. Would these products cause a false positive for steroids?


Subj: Second hand marijuana smoke?
Date: 4/11/2007
I have tested positive for marijuana with a hair test. I do not smoke marijuana but my husband is a medical marijuana patient due to chemotherapy. I feel some how I was exposed but the lab says this is not possible. The testing was for pre-employment. Is it possible to have a positive hair test due to exposure?


AskDocWeb: Yes, the smoke is readily absorbed by hair.

Subj: Tested positive for barbiturates
Date: 4/11/2007
My son tested positive for barbiturates. The only medication he took within the past week before the test was Excedrin (aspirin, caffeine, and acetaminophen) and a generic brand of the same kind. He had been sick with the flu (vomiting/diarrhea) for 8 days. Could this cause a false positive?


AskDocWeb: Nothing in your list could have produced a false positive.

Subj: Food that can cause false positives
Date: 4/12/2007
Do you know of any types of food (other than poppy seeds) that can cause a false positive?


AskDocWeb: Blue lettuce and prickly lettuce, Mormon Tea, tonic water have all been reported to cause false positives.

Subj: Nyquil/Night Time
Date: 4/13/2007
I have been using Methadone for almost 2 years now. Recently I entered a program that is slowing taking me off of the Metrhadone to them, be put on Suboxone for a short time until I am CLEAN! I am in the program because of the Child Protective Services. I have been going down 5mg methadone a week. I started at 145mg and I am now at 70mg. My urine results were as follows … +25,000ng/ml .. 5780ng/ml…9460ng/ml… Now they are 13,000ng/ml! The CPS swear I have been using street methadone and I haven’t at all, but I have been using Nyquil for my chest/throat cold, plus it helps me too sleep because of the withdraws. I know that Nyquil/Night Time can make you test positive for methadone for 2 days but if you use methadone can it make your levels rise? Please help me here my kids are on the line … this is serious!!! I’m desperate!


AskDocWeb: It may be safer to avoid all over the counter cold products if you do any type of drug tests, they could make your levels rise. If you told them after the test that you took Nyquil, they would think you were trying to get out of the test results.

Subj: Air Force drug testing
Date: 4/14/2007
I’ve been taking Amoxicillin 250MG for a tooth infection (cavity) for a bit now, and I’m about to join the Air Force. Will this affect my drug test, and show me as positive for Cocaine with THEIR drug tests? I’m nervous, since I only get one chance at this…


AskDocWeb: Sorry Michael, we don’t know what kind of test the Air Force uses for drug testing. Maybe you could find out and share that here with others.

Subj: Synephrine?
Date: 4/14/2007
Good day! I just want to ask if synephrine the natural herbal extract now used as an active agent in fat burner products can also cause a false positive result for amphethamines just like epherine, base from the chemical structure it has an OH group in the para position. Thank you very much!


AskDocWeb: So far, it has not been reported to cause any problems.

Subj: Ambien?
Date: 4/15/2007
Can anbien fail a urine test?


AskDocWeb: It’s not on the list as causing a positive drug test.

Subj: Things that cause false positive
Date: 4/15/2007
In September 2006 I took a hair follicle test and the results were positive for cocaine. I was wondering if the Fahrenheit diet pills, Rockstar energy drinks, marble mocha machiattos with extra shot of espresso, Sudafed, Advair, Prednisone, Relacore, Albuterol inhaler, Midol, Tylenol, or Motrin IB would cause false positives for cocaine? The last time I tried “coke” was April 22, 2006 and before then it was about October 2003. I read an article about people with naturally dark hair having a higher chance of getting a false positive compared to those with natural light hair colors. Is there any truth to that??? Please help. I miss my four children badly…


AskDocWeb: We’ve heard that rumor about hair color too, so far it is just a rumor. All the products that have been reported to cause a false positive drug test are listed here.

Subj: Afrin
Date: 4/18/2007
My son tested positive for cocaine. He does not do cocaine, but did use some Afrin. Could this be the cause?


AskDocWeb: It is possible, Afrin has been reported to cause a false positive on some tests.

Subj: Tested positive
Date: 4/19/2007
I have tested positive for every drug test over the past year and have NEVER taken it, NEVER seen it, NEVER been around people that have done it, do NOT know what it does, or even what it looks like. WHY? I am currently having a real nervous breakdown and need more information on it.


AskDocWeb: You would have to tell us what drug you tested positive for and what over-the-counter products you are taking before we can answer.

Subj: Zithromax
Date: 4/19/2007
Can zithromax provide a false negative on a urine screen for cocaine


AskDocWeb: Zithromax has not been reported to cause a false positive or negative in a urine drug test.

Subj: Novocain
Date: 4/20/2007
Can Novocain cause a false positive in a hair test? I had one very large dose of Novocain for a dual extraction during oral surgery. A subsequent hair test came back positive for cocaine. Is this really possible? I am quite upset about this.


AskDocWeb: Novocain is a trade name for the drug procaine hydrochloride. Because the name Novocain is similar to cocaine, there is some confusion as to the nature of procaine. “Pro” means, in place of, and “caine” comes from the word cocaine. It’s an alternative to cocaine that acts as an anesthetic but is non-toxic, free of side effects, and is non-addictive.

Subj: Predizone, Sulfer Drugs and Ambien
Date: 4/20/2007
I have never done drugs but today I took a Drug Test for a new Job and I failed because they said I tested positive for Methadone. I do take Prescribed Predizone, Sulfer Drugs and Ambien. Could these have caused the failure


AskDocWeb: Neither Prednisone nor Ambien should cause a false positive. You didn’t say which sulfa drug you are taking so I can’t help you with that one.

Subj: Tested positive for benzo’s
Date: 4/22/2007
Hello, thanks for reading about my problem. I tested positive for benzo’s for two drug tests I took from my meth clinic. I know I didn’t take any. Just trying to see what could cause a false + for benzos.
