What do we tell the MRO?
My husband is on Azithromycin, Hydrocodone and takes supplements: B2, B12 and Hemp Oil caps (you can get these online). He took a drug test yesterday. What are the chances of him passing? How and what do we tell the MRO?
AskDocWeb: As a general rule, it is a good idea to disclose everything you are taking, both prescription and over-the-counter remedies, herbs and supplements at the time of testing. In our opinion those who are subject to drug testing are asking for trouble if they take or use Hemp Oil in any form.
Is this possible?
i tested possitive for benzodiazapiens and the only thing i was using was oxymethalone steroids, is this possible?
AskDocWeb: Anadrol (oxymetholone) is a synthetic steroid which belongs to the class of anabolic steroids. It has not been reported to cause any false positives on urine drug tests for drugs of abuse.
Test shows meth
i will try to make this short. i do not drink or do drugs other than what was subscribed from a doctor. i have a disk pressing against a sciatic nerve and have been given the following medications. Cyclobenzapr 5mg, tramadol hc l50mg, hydroco/acetaminop5-500mg, meloxicam 7.5mg. i also take to over the counter medications 1 is equate headache relief(acetaminopen, aspirin) and equate acid reducer ranitidine 150mg. could any of these have given me a possitive for meth? i went to my first visit at a pain clinic and they said i faid the test because i was showing meth. i do not do any drugs other than what i listed.
AskDocWeb: Only one of your meds is on our list. Two sources say that Ranitidine may test positive for methamphetamines; Redwood Toxicology Laboratory (Reference 33) and Blue Grass Drug Screen, Inc. (Reference 52). Both of those run first class drug testing laboratories so they should know.
How long does Xanax stay in your system?
Hello I have a question. I'm scheduled for a pre-empolyement drug test. I have recently two 2mg of xanax for two day's. I was just wondering how long would it take for me to pass a drug test because I have heard that different benzodiazepine stay in your system for different times.
AskDocWeb: There are several reasons for the different times that you have heard. The amount of dosage, length of time it is taken, physical condition of the body, your race, etc.. If you are a chronic user of Xanax, it can be detected a month or more after last dose. The average half-life of Xanax is 11 hours and it takes about 5 half-lives for the body to completely eliminate a drug from the system. After that your body still has to eliminate the metabolites, which is what the drug test is designed to detect. That means that optimistically the soonest you would pass the test is three days.
False positive for methodone?
I have a question. I have a false positive saliva drug test. I am under dr care and take soma as a muscle relaxer. I also take Benadryl 50mg bid. Will this give me a false positive for methodone?
AskDocWeb: Benadryl (Diphenhydramine) has shown up as false positives for benzodiazepines, PCP, and tricyclic antidepressants but not as methadone.
Mouth swab drug test
i was given a mouth swab drug test today at work.. i tested positive for PCP and methadone, i have NEVER touched either of these.. the ONLY medications i've taken over the last few days are otc cold medicine, buspar and hydrocodone (which i'm prescribed and didn't show up on the test!!!) after i went in, my bestfriend/coworker had to go in and she tested positive for pcp and opiates and she's never taken that.. now we are suspended until we can test negative and i'm not sure what just happened!!!
What just happened???
AskDocWeb: Your drug test may have produced a false positive or false non-negative result. Did they authenticate results with a confirmation test at an outside laboratory? If not you may have a legal claim for loss of wages but you would have to check with an attorney to find out.
Blamed Vics Vapor rub
My husband just failed a hair follicole and the blame is Vics Vapor rub. the cutoff on the test was 500 and his level was 3322. now he's saying false positive bc he used vics. is there a way to tell between vics and the use of Meth?
AskDocWeb: Yes, it is called a GC/MS confirmation test. The GC/MS stands for Gas Chromatography/Mass Spectrometry. The original sample is tested to confirm or deny the results of the hair test. It is an expensive test but it will prove exactly what is in the test sample, which eliminates false positives.
Poppy seeds muffin and opiates
i recently took a 12 pannel drug test and came out positive for opiates. ive been sober for 11 month. the morning of the test i ate a poppy seed muffin could that test positive. and they sent it to the lab will it show that i have not igested any kind of drug containing opiates.
AskDocWeb: The problem with poppy seed muffins is that the seeds contain a small amount of morphine and codeine, which would both show up as opiates on a drug test. There are some conditions for ruling out poppy seeds as the sole source of morphine and codeine but there is no guarantee that these will be applied in your particular situation. The conditions are:
Please, I'm just taking micardis plus for initial hypertension. Is there any negative or dangerous side effects of taking this medicine with ocational alcohol or marijuana consumption? Best Regards,
AskDocWeb: Consuming alcohol while taking Micardis Plus may have additive effects in lowering your blood pressure. We have no data about using marijuana with Micardis Plus. If you are concerned about drug interactions, always discuss the risks and benefits of a new medication with your doctor.
History of use
I recently filed order of protection against my husband for domestic violence. We have young kids who are in my custody. He wants visitation, because of his criminal past the judge ordered a urine analysis first he tested positive for marijuana. Just this week he was tested again and amphetamines showed very faintly, the judge ordered further testing to determine whether this was positive or not. Does this most likely mean that amphetamines are in his system? I know he has a history of use.
AskDocWeb: With a history of use the chances are high that he actually had amphetamines in his system at the time of the test. However, with urine tests there is always a small chance of a false positive. That's why they send the sample out for additional testing, to confirm the results.
