Subj: False positive for methadone?
Date: 9/28/2010
My daughter is in rehab for alcohol. She came home on the weekend on pass. She was with us the whole time. She got back Sunday and on Tuesday they gave her a drug test. She tested positive for methadone. She is not a drugger, just alcoholic. She is on medication, geodon, remeron, visteril, has been on antbiotics while she was there. Also benedryl. Would those cause a false positive for methadone?
Madge

AskDocWeb: None of those medications have been reported to show up as methadone. The only ones that have are Bentyl, Elavil, Nyquil, Phenergan, Vicks Formula 44M, and antihistamines in general.

Subj: Yeast infection
Date: 9/29/2010
I have had a yeast infection for over a week and unknowingly gave it to my partner. My signs started to go away pretty fast though his did not. His penis is peeling, dicharging white colored discgtarge alot, it hurts for him to touch/ urinate. I have given him some amoxicillon to help get rid of it. Is there anything else i can give to help get rid of it faster? And he would like to know if a doctor would prescribe a pain killer for it because of how horrifying the pain is to him. My fiance is also on probation and is getting drug tested soon will any of the antibiotics/ pain killers cause him to fail the test?
Heather

AskDocWeb: If he is on probation then giving him prescription drugs that belong to someone else may result in loss of his probation. It is illegal to use someone else's prescription drug. Although you suspect that what he has is a yeast infection, he would have to consult with a doctor to find out for sure. And yes, the doctor can prescribe something for his pain.


Subj: Dilude?
Date: 9/29/2010
Hello, I was reading quite a few comments about Drug Testing on your pages of False Positives. I just tested a week or two ago. I was told it came back as a Dilude? That either I had taken something to clean out my system, or that it may be an indication of Kidney Problems. I did NOT take anything to clean out my system, but I was wondering if Green (Herbal) Tea, can affect the results of a urine drug screen? All I had taken in addition to that was, Naproxen 500 mg., Prilosec,(Omerprazole-The Generic)Over-the counter PM's from Wal-Mart, like (Tylenol PM's) and over-the-counter allergy medication for seasonal allergies (CVS Pharmacy Brand) Can you tell me if Green Tea or any of these may have had a role in the Drug Screen being affected? Thank you for your time.
April

AskDocWeb: The only tea on the list is Coca tea, not Green Tea. Several of the Tylenol products as well as Naproxen (Aleve) have shown up as false positives on urine drug tests.

Please note that there are some health concerns with using Green Tea.

Blair

Subj: Hydrochlorothiazide or sumatriptan succ
Date: 9/29/2010
Can hydrochlorothiazide or sumatriptan succ cause an false positive? I'm going to have a drug test for a job and i was just wondering.
LettyS

AskDocWeb: We found a few reports of Hydrochlorothiazide causing false positives but were not able to find a good reference for that. Searching the database for sumatriptan returned no results.


Subj: Darvocet?
Date: 9/30/2010
What other medicines show up in a urine test that would consider to be darvocet
Jenifer

AskDocWeb: Darvocet (also sold under brand names Balacet and Propacet) is a mild narcotic analgesic prescribed for the relief of mild to moderate pain - it can be detected in your body for approximately 5 days after use. Darvocet is a combination of acetaminophen and propoxyphene. It is the Propoxyphene that is classed as a narcotic, which can show up in a drug screen. Other products that contain Propoxyphene can show up on a drug screen include the following:
  • Balacet (combined with Acetaminophen)
  • Darvocet A500 (combined with Acetaminophen)
  • Darvocet-N (combined with Acetaminophen)
  • Darvon Compound 32 (combined with Aspirin and Caffeine)
  • Darvon Compound-65 (combined with Aspirin and Caffeine)
  • PC-CAP (combined with Aspirin, Caffeine)
  • Propacet (combined with Acetaminophen)
  • Propoxyphene Compound 65 (combined with Aspirin and Caffeine)
  • Wygesic (combined with Acetaminophen)
Acetaminophen increases the effect of Propoxyphene.

Subj: Protonics?
Date: 10/1/2010
I was hurt on the job and I took a drug test. It showed THC and I have been swabbed and urine tested both were negative except the one I received from the company. I had taken protonics could that hurt me?
Lisa

AskDocWeb: Not protonics but just in case you might have misspelled it, Protonix has shown up as a false positive for THC (Ref: 37).


Subj: Fat burner?
Date: 10/1/2010
I have been taking a fat burner with 1,3 dimethylamine..can this show up for false positive for amphetamines on a 5 panel drug test?

AskDocWeb: 1,3-Dimethylamine is the chemical name of Geranamine. The chemical structure of Geranamine is similar (although not identical) to amphetamines so there may be a possibility of a false positive, but so far there is no documentation on that.


Subj: This doesn't make sense
Date: 10/2/2010
Please help! At first I was scared because this is a legal issue but now I am angry because this just doesn't make sense. I am a patient at a pain management center and on Sept. 15th 2010, I had an appointment where they took my urine for a urine analysis. There are three drugs I have been accused of taking or rather that they "found them in my urine". The first one is PCP. Really?? PCP?!?!? Unreal, but that isn't all. I then got a call that they detected Soma??? (Not even sure what that is.) Then I got a paper in the mail stating that my urine showed that I used meprobamate!!! First of all, I have NO IDEA what any of those are for. Second of all there is NO possible way that any of that should have been in my system! Here are a list of medications that I DO take on a regular basis...BECAUSE THEY ARE PRESCRIBED TO ME!!!:
Norco 10-325 2 pills 4 times a day
Oxycodone 15mg. 1 pill twice a day
Zolpidem 10mg. 1 pill at bedtime
oxcarbazepine 300mg. 1 pill twice a day
bupropion 100mg. 2 pills in the morning and 1 pill in the evening.
Phenergan 25mg supp. 1 rectally every 4 hours.
Acetaminophen PM 500mg
Diphenhydramine 25mg 2 pills at bedtime.

That is all that would have been in my system at that time...or even NOW!!! Why would ANYTHING like that show up in my system when I have NEVER taken anything like that??? Please help!!! Thank you,
Sherrie

AskDocWeb: When someone does not know that a false positive is possible, it can come as a shocking surprise, as you found out. First you need to know that the EMIT urine tests are not perfect. They do have error rate, which means that these test sometimes misidentify what is present in a sample and sometime miss what is there. Urine tests are known to have a problem correctly identifying several of the drugs you are taking; Oxycodone, Bupropion, (Wellbutrin), Phenergan, and Diphenhydramine. Getting a GC/MS confirmation test is about the only way to sort this out. If you have to pay for that test out of your own pocket it may be worth it if you want to remain in the pain management center. Just remember to keep copies of everything to document this experience because it could happen again.


Subj: Fioricet?
Date: 10/3/2010
Can fioricet cause a false positive for opiates. I recently tested urine, positive for opiates and had taken Fioricet for a migraine. Is this a false positive?
Marsha

AskDocWeb: Although it is possible, you would have to get a GC/MS confirmation test to find out for sure.


Subj: Positive for alcohol
Date: 10/4/2010
I go to a methadone clinic, and my dose is 97mg. daily (liquid form). I am u.a.'d weekly. I'm given anabuse and breathalized daily as well. Within the past month I have come up positive for alcohol. I DID NOT consume any alcohol!! Of course they hear this ALL the time, as you can imagine. I've got a good reputation there, and will admit to something that I've actually done. The problem is this. I DID take A LOT (approx.18-20) Benedryl (Diphenhdramine) 50 mg. liguid caps. daily for about 3 weeks. As to why I did this is irrelavint at this time. The problem is that my past 3 u.a.'s have tested positive for alcohol. This itself is bad enough, but the clinic had an ETG test as well which ALSO came up +. I've been told there is no further test that can be done. I've learned that women that are pregnant or diabetic have u.a.'s that test positive for alcohol and are required to put a tablet in there u.a.. I know I'm not pregnant but thought perhaps I'm pre-diabetic. My counselor informed me that would perhaps explain the +'s on the first 3 regular u.a.'s but not on the ETG. I am at a loss! I've made an appt. to see my regular Dr. and also the clinics Dr.. Do you or your readers have ANY thoughts on this? Has anyone had a similar story? PLEASE PLEASE HELP ME!!!
Kristin
