False Positive On Drug Test For Thc
I have been injected with steroids 3 times in the last four weeks, I am prescribed 70mg Vyvanse, and 1800 Ibuprofen daily and I have my first pee test on Tuesday with my PO and I am very scared that it will show thc. Is this true and would I still be in trouble even though my PO is well aware of what I am taking? ## Hi Michelle, I can certainly understand your concern for THC showing up on your drug test, since Ibuprofen is known to cause false positives for Marijuana (THC). In my opinion, your best bet would be to reference any articles of information stating that this is in fact a possibility that they should be made aware of. I would also bring copies of your prescription to the lab and even let your PO be made aware of this as well. I think a great resource for false positives is: a... ...

However, there are quite a few over the counter products that can, far too many for me to list them all, actually. What else were you taking? If you can post back with this information, I will gladly check for you. ...

False Positive Drug Test
I have taken numerous over the counter medicines for sinus headaches, allergies, and pain relivers containing ibuprofen in the last 6 months. I have to take a pre employment drug test soon. I fear some of these medicines might show up as an illegal drug in my hair follicle drug test. Do I need to worry about this? ## It really depends on what you've taken and the quality of the test that is done. False positives have become fairly common. Just as an example, on a poorly done test, the Ibuprofen could give a false positive for Marijuana. This happens much more frequently with urine tests, however, there is always a slight possibility that it could do the same on other tests, as well. There are also reports of many over the counter cold and allergy preparations causing false positives... ...

i am on at least 10 different medications ive done research and over half of them can cause positive or false positive for THC. my question is if one individually can cause this what happens with all five of them together and possibly the rest? the ones i know of so far are robaxin, naproxen, promethazine, voltaren gel, and the flector patch. the others i am uncertain of they are cymbalta, trazadone, seroquel, nexium, and magnesium. i have had multiple test come back positive and i do not use marijuana, i am trying to explore every avenue and get as much research and proof to support my case. any help will be greatly appreciated. ## If the military gave you Methocarbamol or any other meds dont worry its all on record. ## I know for a fact that promethazine can, as it just happened to me... ...

Amphetamines False Positive Drug Test
I have somehow tested positive for amphetimine but the only drug that I touch Is marijuana. How is this possible? It was a urine test done in a hospital. ## If u take allergy pills that sometimes shows up as a false positive for amphetamines if u haven't then I don't know how it happened that's all I know ## It should occur from just marijuana. However, Dloc is correct, these false positives can be caused by other medications, even over the counter products. Did you take anything? ## Nope. Nothing. Not unless you count Tylenol. ## i have had a positive test result for amphetamine.i have never used the drug.the only thing i take is motillium for sickness which contains domperidone.can you help ## @nicole, If you or someone you know is facing serious consequences such as a job... ...

False Positive For Oxycodone
I currently take hydrocodone 5mg 4x, albuterol inhaler, ranitadine, vistaril, chantix, mobic, gabapentin and i have a medical marijuana card.. i was recently on doxycycline, and nizoral cream. I'm also a caretaker for someone. I handle their medication on an almost daily basis. I went to my doctor and she said i tested positive for oxycodone....there has to be some mistake. could i have absorbed any from handling the medication ## No, you shouldn't absorb enough for it to be detectable on a drug test, since the tablets are coated. It was more than likely just caused by the Hydrocodone you are taking, if the doctor is using a less expensive, non-certified test. Semi-synthetic and synthetic opiates are well known to cause false positives for their relatives on those types of tests... ...

False Positive For Meth
im taking naproxen sodium/anaprox ds,sulfameth/trimethoprim/bactrim ds, for an infection and percocets for pain, and recently started using sudafed for my sinuses would any of these cause a false positive for meth? ## Based on my research, none of the drugs mentioned are "notable" for causing a false positive for meth: Naproxen (Aleve) - false positive for THC, Marijuana Anaprox - false positive for THC, Marijuana Bactrim - may test positive for benzodiazepines Percocet - will test positive (not false) for opiates "The chances of you getting a false positive depends on the quality of the laboratory that does the testing. There seems to be about 1,200 of these labs in the United States currently testing for drugs. Less than a 100 of these meet federal standards and most of th... ...
