Ok thanks can any drugs cause a false positive for Thx? I was positive for that but i was around marijuana smoke for less than 5 mins i don't smoke either
Health Professional: Dr. Muneeb Ali, Doctor (MD/DO) replied 7 months ago

Actually, there are a number of things which can cause a false positive for cocaine, including various antibiotics, OTC medications, prescription medications along with things like food products which contain the cocoa leaf, coca tea among others.

In your case, it is VERY LIKELY that the positive test for cocaine was due to AMOXICILLIN. It is a known fact that amoxicillin can cause false positives for cocaine in normal urine analysis tests. This occurs commonly in many patients who have been using the antibiotic for other purposes. The best way to clear yourself of this issue would be to ask them to run a GC/MS test on the SAME urine sample which can easily determine that the cocaine positive result that you had was a false positive test.

A GC/MS is MUCH more accurate in determining which drug was used and it will accurately determine that you in fact used amoxicillin and NOT cocaine.

For THC, ibuprofen has been known to cause false positives as well as other NSAIDs

Do you have any more questions?

But I havnt took any amoxicillin in like 4 days
Health Professional: Dr. Muneeb Ali, Doctor (MD/DO) replied 7 months ago

Amoxicillin can stay in your system for upto 7 days especially if you were using it for more than 2-3 days.

And if you did not use either cocaine or THC, then the GC/MS test will come back as negative, it is a common issue to find amoxicllin causing false positives for cocaine, the THC can be false positive because of the excedrin that you used.

I forgot about that i bn taking the dollar general brand similar to benadryl
Health Professional: Dr. Muneeb Ali, Doctor (MD/DO) replied 7 months ago

Benadryl or diphenhydramine (the drug in benadryl and oither brand names) causes a false positive for benzodiazepines and PCP but not THC or cocaine.

In your case i think excedrin and amoxicillin are the culprits which should be easily determined on the GC/MS test.

How long does amoxicillin stay in ur system?
Customer reply replied 7 months ago
I'm sorry for all the questions this is all very confusing for me
Health Professional: Dr. Muneeb Ali, Doctor (MD/DO) replied 7 months ago

As I said earlier, amoxicillin can stay for up to seven days in your system after the last dose IN SOME CASES, but usually, it does leave the body after 3-4 days. Your last dose was 4 days ago, so it is conceivable that it is still in your system.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
