False Positive On Urine Drug Test For Methamphetamine (Top voted first)

Updated

My son use to take meth, but has been clean for over 70 days. He takes 60 mg ritlian a day, 20 - 40 mg lasix a day, potassium each day. On days that he has a migraine headache he will take 2 Excedrin Migraine tables with a can of coke, and repeat it every 4 - 6 hours until the headache goes away. He is on probation so has to have two or three urine drug test a week. Some come back as dilute, so they give him lead way on them as he takes the lasix and drinks lost of water working outside all day. But once in a while when he has taken all his meds it come back positive. Will this combination of meds call a false postive?

The Methylphenidate in the Ritalin has been known to cause false positives for various types of amphetamines, including methamphetamines.

Even being on probation though, that is a lot of tests to have to take in one week. Is there some special reason they test so frequently?

No it should have been 4 a month now. It is nothing special, but once he finishes 3 months without a dulite or postive he will only have to have one or two a month.

There are ALOT of over the counter meds on the market that do show up as amphetamines on urine drug screens, also there are a lot of prescription meds like aderol (& probably Ritalin) that also show up as amphetamines...bring the bottles from EVERY medication he's taken in with u for the next drug screen & talk 2 the personnel giving the test about the concerns ahead of time...good luck!

NO that combination will not cause a false Methamphetamine results, especially if it is confirmed by LC/MS./MS or GC/MS. Meth is a very hard addiction to break, and if you want to consider him clean, he needs to be clean of all mind altering drugs.

Well Doctor John, I almost hate to inform you that you are wrong. You kind of called yourself out on it by stating:

"especially if it is confirmed by LC/MS./MS or GC/MS." What you were basically saying is you won't get a false positive IF it is confirmed LC/MS./MS or GC/MS. Since you weren't the one doing the testing, you don't know how it was confirmed or if it was confirmed at all.

It is irresponsible of you to say that it is impossible to get a false positive. It is absolutely appalling that you would hint or lead this man to believe his son is still using
When you are not a part of their lives and know nothing about them. Is it possible? Of course it is, but its also very possible his son is ckean and he did receive a false positive.

I doubt you are a real doctor, but if you are then you don't need to be. Making assumptions without any proof or facts is amateurish at best. Its unethical, immoral, and downright disgusting.

I take oxycontin, morphine, xanax, abilify, klonopin and triazolam and came up positive for for methamphetamine. I was also very sick, took different cold meds and had surgery on my kidney. I was given antibiotics, fentanyl and diuretics. Would any of these cause this?
