if i had the list of prescriptions you are taking now perhaps i could be of more help. amphetamines are in a class of drug called sympathomimetic amines and some decongestants (like pseudoephedrine) and even some combination cold medicines can cause a false-positive result. some over-the-counter weight loss medications often contain them. just give the list to your doctor and have him/her figure it out. if you have not been taking any amphetamines then just have the test repeated.
what medications can result in a false positive for illegal methamphetamine in a urine analysis who's never used before. i'm having bariatric surgery my labs came back pos. for methamphetamine when i've never done any drugs in my 40yrs of living. are there otc/prescribed meds that could cause this? because of the results they want me to do treatment & wait a yr before surgery-which is for my severe acid reflux/obesity. i'm mortified since i've never used illegal drugs i'm on several prescriptions it has taken me 20 yrs to finally get my insur. to cover this surgery just to have this happen? ! please help!
