I dont do any of those. And ever since I went to the hospital for a re check I have failed my drug test. I had antibiotics and what ever else running threw my IV, then taking my scripts, which are: propranolol HCL 20 mg 4x a day, Norco 7.5/325, Sulfameth/ TMP DS TAB 2x a day, cephalexin 500 mg 1 capsule every 6 hrs, propythiouracil mg PO TAB 3 tabs 2x a day, Klo-Con M20 ER 20 MEC 1 tab 2x a day. I want to stop taking them just so I can see my kids again but then again the infection would only get worse. I hope you can help me.

I checked for all your medications and the and none give a false positive for amp & meth. I am very sorry about your situation.
Please click on link below to check and see for yourself about false positive readings:
The only ones are antibiotics but they can cause a false positive for heroin and cocaine.-
I hope you get to see your kids very soon.-
All the best and take care.-

I am not an expert and drug test are horrible about false positives and negatives, but one med you listed is sulfameth, the fact that it has the suffix meth would tend to make me believe it might show a false positive for uppers of various types. ChristineATU has a link and info on what will test false positive, friend her by clicking on her avatar and look for ask private question and post a pm to her. She may answer this anyway without you having to do that. You know that psuedophed will test positive for meth, if you took any of that for your sinuses or allergies, it may have done it. Ask whomever is testing you to send your specimen to the lab for a double check and offer blood or hair to show you are earnest and honest and bring all rx bottles in with you.

The following excerpt is from an article I found. There are several links you could review by typing in "False Positives" or "Drug Screening." David Kopel is the leading expert in this field and has published several articles and books on this subject. Even the chemicals used in test kits have short shelf lives and can cause false positives. But the number one reason for false positives is poor quality control in the labs themselves. Most have less quality control standards in place than most restaurants. I wish you good luck and you have rights to appeal these findings.
Laboratory slip-ups are to blame for many of the mistaken test results. But even perfect labs running perfect tests will also find many false positives.
False positives are caused by:
*Nasal decongestants such as Dristan, Neosynephren, Vicks Nasal Spray, and Sudafed, which cause false positives for amphetamines.
*Poppy seeds like those on a dinner roll, which cause false positives for opiates. Even the highest-quality test currently available, the GCMS test, still confuses poppy seeds with heroin.
*Pain relievers such as Advil, Nuprin, Midol, Trendar, or any medicine containing Ibuprofin cause false positives for marijuana.
*Antibiotics such as amoxicillin or ampicillin cause false positives for cocaine.
The above list is only a beginning. Most substances which people have in their blood have never been tested to see if they cause false positives. Indeed, even some natural body enzymes cause false positives. According to research validated by the Congressional Office of Technology Assessment, melanin, the natural pigment which makes skin dark, can cause false positives for marijuana
