Can amoxicillin cause a false positive for cocain on a drug test?

Can amoxicillin cause a false positive for cocain on a drug test?

No Proof: The only medical trial to test this was done in on 33 Amoxicilin pts in 2008 and no false positives were found: http://jat.oxfordjournals.org/content/32/4/315.full.pdf Contrast this with the thousands who claim this to be true on the net and we have a dilemma.

Tested positive for strep. On day 6 of 10 of amoxicillin, and I got a tattoo today. Am I okay?

Depends: You are okay as far as your sore throat is concerned, but there is question about your thought process. Tattooing is a form of self-mutilation. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. Get HPV vaccine ...Read more

Can augmentin (amoxicillin and clavulanate) cause c diff? Doc said i tested positive. Only med i took was augmentin (amoxicillin and clavulanate).

Can augmentin (amoxicillin and clavulanate) cause c diff? Doc said i tested positive. Only med i took was augmentin (amoxicillin and clavulanate).

Yes -: The reason for this is that Augmentin (amoxicillin and clavulanate) doesn't just kill the bad germs in your body, but it also kills a number of the good bacteria in your large intestines that keeps the c difficile bacteria in-check. Metronidazole or else, vancomycin by mouth (for example) can treat it, along with minimizing lactose products during this period, and the possiblre use of probiotics. Discuss this with your doctor. ...Read more

But if the problem persists or worsens, call your doctor since the problem may not be from the sinus at all. ...Read more
