False Positives ForumThis forum is intended to help those who Do NOT Abuse Drugs. We do NOT support the illegal use of any substance. If you have experience with false positives, share your experience. What would you tell someone about drug testing and false positives? Please remember that we do not give medical or legal advice.
Why would oxycodone show up in my pee test?
AskDocWeb: The first thing that comes to mind is that you have it in your system. If you haven't used oxycodone then another possibility is that you have used hydrocodone, which has been reported to show up as a false positive for oxycodone. A third possibility has been suggested: It appears that some people metabolize hydrocodone in such a way that it breaks down into oxycodone in their system and can show up on a urine test.
Subj: Can Septocaine affect a drug screening?
I need to do employment drug test, today my dentist gave me 1 capsule of Septocaine (articaine) with 1:100,000 epinephrine, will it affect the drug screening?
AskDocWeb: No, the only dental anesthetic that has been reported to show up on a drug screen is Novocain.
Subj: Nightmare in America
My husband tested positive for amphetamines. He has taken urine tests for years and never has had an issue, never tested positive. He does not do drugs. He had gotton sick and he was prescribed by a doctor to take predisone, ventoline hfa, antibiotic and cough syrup with codine. He was on the road and misplaced his inhaler so he bought a vicks inhaler over the counter. He tested positive for amphetamines and was pulled from work for 2 weeks. He had to pay 400.00 to a SAP and had to go to 2 aa classes and now has to take 6 random urine tests, where he has to pull up his shirt and drop his pants and underwear, turn around in a circle and urinate in front of a man.
We have tried to fight this with very little information and now we are not allowed to speak to the MRO or anyone Sanford. We have been instructed to speak to Sanfords attorney. It is a nightmare because if you dont do drugs there has to be another explanation. I can't believe this is happening in America where your life can be ruined by tests and MRO's. There are pages and pages of similar stories. We need to keep people who do drugs off the road but we also have to protect people from being wrongly accused. Can you please help with this nightmare!
AskDocWeb: It would seem that the pivotal question here is: "Was his urine test confirmed by GC/MS testing?" If not then there is a possibility that you good people are going through this nightmare because of a false positive drug test result. This is why we put together the list, to help the innocent defend themselves against such injustices. That list gives links to references that you can take to an attorney if you decide to go that route.
Subj: Tested positive for amphetamines
I have recently tested positive for amphetamines but I have never done illegal drugs. The only thing I took within the week before the test was Lyrica, Flexeril, Nyquil, Sudafed, and Claritin D24 hr. Would any of these cause a problem? I also have small intestine damage, would that cause problems with breakdown of medications?
AskDocWeb: There are several references that say both Sudafed and Nyquil have shown up on urine drug tests as a false positive for amphetamines. The damage to your small intestine is not likely to cause any problem on a drug screen for drugs of abuse.
Subj: Why is this happening?
Adderall (amphetamine/ dextroamphetamine) Condition: ADHD Dosage: 3 x 20 mg oral tablet three times per day None albuterol Condition: Asthma, Maintenance Dosage: x 200 mcg inhalation aerosol as required when needed alprazolam Condition: Panic Disorder Dosage: 1 x oral tablet one time per day For the treatment of Irritable Bowel Syndrome and P.M.S. pain Bentyl (dicyclomine) Condition: Abnormal Uterine Bleeding Dosage: 1 x 10 mg oral capsule every six hours None Celexa (citalopram) Condition: Anxiety and Stress Dosage: 1 x 20 mg oral tablet one time at night None HyoMax SL (hyoscyamine) Condition: Irritable Bowel Syndrome Dosage: 2 x 0.125 mg oral tablet two times per day None Ibuprofen PMR (ibuprofen) Condition: Rheumatoid Arthritis Dosage: 1 x 600 mg oral tablet two times per day None Prevacid 24HR (lansoprazole) Condition: GERD Dosage: 1 x 15 mg oral delayed release capsule one time per day None tramadol Condition: Pain Dosage: x 100 mg/24 hours oral tablet every eight hours Condition: Rheumatoid Arthritis Dosage: x 100 mg/24 hours oral tablet None Vistaril (hydroxyzine) Condition: Anxiety Dosage: 1 x hydrochloride 25 mg oral capsule every six hours None Vitamin D (ergocalciferol) Condition: Vitamin D Deficiency Dosage: 1 units 500000 intl units/mL oral capsule as required once a month. I take all these medication I have uterus cancer and I came out one day with meth and another day with THC why is this happening?
AskDocWeb: It appears that several of your meds could account for this. Adderall has been reported to sometimes test positive for meth, and both Ibuprofen and PPIs may test positive for THC. Dicyclomine has also shown up on drug screens. With so many possible causes you would need a GC/MS confirmation test to sort out what is actually in your test sample. Hopefully they will allow you to do that.
Subj: Diabetic or kidney disease
Will I fail a employment drug test if I am diabetic or have kidney disease? Should I tell the testing lab that I have these two conditions?
AskDocWeb: Those two conditions do not always cause a problem on urine tests but informing those doing the testing may be a good idea. That may help avoid a nasty surprise.
Will lisinopril show positive for cocaine on an urine test?
AskDocWeb: No, Lisinopril has not caused any false positive results on urine drug testing for drugs of abuse.
Subj: Positive for butalbital?
I take now and then Lorazepam, not long ago I was taking doxycycline for treatment of possiable lime disease, and I take two 400 mg motrins now and then for pain. I just took a drug test for a job and it cam back poss for butalbital???? Could that be from anything I take or for any non prescription drug? The only other thing I can think of is tylanol and I drink a lot of the Monster drinks, they are loaded with caffine.
AskDocWeb: None of what you list has been reported to show up on a drug test as butalbital. Were they testing specifically for butalbital? The 12 panel tests that we have researched do NOT specify which barbiturate is found in a sample, only that one may be present. The table below shows what they test for on a 12-panel immunoassay.
