Amoxicillin False Positive Drug Test

Updated

When tested for drugs, can amoxicillin give you a false positive? If so, how much amoxicillin would I have to use to give a false positive for cocaine? Also, will drinking lots of water right before the test cause it to show up diluted?

Yes, Amoxicillin can give a false positive for Cocaine, however, there is no specific amount to tell you, because this is generally caused by an unreliable test, not the antibiotic itself.

And yes, drinking more water/fluids before the test may lessen the chances of its doing so, but in most cases, it will be noticed that your urine is diluted.

This antibiotic may cause side effects, such as: nausea, drowsiness, diarrhea and skin rash.
