Can this seizure med cause a possitive for methamphetmine? I Take 50mg morning & night, and allergy meds. Is there a test for meth or is it just amphetamine cause the lady said I was positive for methamphetimine. Is this possible when I have never have even tried the drug?

I take Topamax too. After testing positive for a synethnic form of THC and I know I am clean. I starting researching about Topamax. I found that Topamax can in cact make you test positive. I even took a at home THC test and it came back positive a month and a half after failing the test mentioned above. Link one read section about the class Topamax being a Phentermine. Link two read the very last question about prescription drugs and Phentermine's making you fail test positive on drug test. My advice take your pill bottle(s) with you to the drug testing. Feel free to read the entire articles.

Hi sean,

Although I don't think any probation test would cover this specific drug, Topiramate is generally excreted from the body within 4-5 days, in part, due to it's long 21 hour half-life.

The example shown below, puts the half-life into better perspective:
Monday - 50mg
Tuesday - 25mg
Wednesday - 12.5mg
Thursday - 6.25mg
Friday - 3.12mg
Saturday - 1.56mg

I'd say by Friday you should have 95% of it or more out of your system; especially if you're drinking plenty of fluids and eating clean.

I hope this helps!
