None: There is no cross reactivity with tests for Cocaine in the commonly used screening tests for drugs, and xylocaine (lidocaine) or novacaine (or any other) will not show up.

Be aware!: Streptomycin is an old ototoxic antibiotic that can cause permanent hearing lost. It is seldom used due to this side effect! it may be used for multidrug resistant tb! can't understand why dentists in tn will use it.

Does xenical give a false positive drug test?

No: I know of no research that shows xenical can cause a false-positive drug test. All xenical does is block some of the fat from your diet from being absorbed, thus decreasing your calorie intake. This shouldn't cause either a urine or a blood drug test to become positive.

Can I fail a drug test taking the diet pill, ali.?

Hmmm...: Best answer is to tell the tester that you are taking "alli"(i think that is the correct spelling) before you get the test. Honesty is the best policy! of course, stopping the supplement about 1 week prior to the test should give your body ample time to metabolize it out of your system. Ask you doctor just to be sure.

THC protonix (pantoprazole): Yes a false positive test can be obtained but only on the urine dipstick - with the quantitative test there is no false results.
A 30-year-old member asked:

Will metaxalone show up on a drug test?

1 doctor answer1 doctor weighed in
Dr. David Teicheira
Pain Management 36 years experience
Occasionally: Metaxalone is not a drug of abuse, so most labs won't te st for it. Unless someone asks. Most urine tox screens are 2-part: a dipstick immediately to get a rough idea of what you've been taking, and a lab confirmation run on sensitive instruments to break down what the exact meds are in you, and in what concentration
