Phentermine And Hair Drug Test
(Newest replies first)

I took phentermine and my UA CAME BACK CLEAN FOR METHAMPHETAMINE, but now they just did a hair sample. Will it test positive for methamphetamine? It's explainable if it does in the hair, but only if it's for amphetamine. I am in so much trouble.

How many milligrams of phentermine do you think you need to consume in order for it to show up on a hair test? I took a phew pills thinking they were diet pills on amazon and I am worried they will show up on a 5 panel test even though I hardly took any of them.

That's great to hear Marky, congrats! So that basically answers earlier questions that Phentermine should not cause a false positive for methamphetamines.

On a hair follicle test will phentermine show up differently than methamphetamine?

Marky, it may come back as a false positive but from what others on here have said, it seems unlikely. But if you can show them that you are prescribed Qsymia (which contains Phentermine and Topiramate) they should take that into account. If possible I would advise you to show them the prescription before you take your test. I hope this helps and let me know how it goes!

Most urine tests are not meant to pick up phentermine, especially a urine dip test like you would use at home. Also, most hair test are looking for specific chemical compounds called metabolites and if the metabolites are not there then the test will not show it in the results (negative). In order for a hair test to be positive it will have to have methamphetamine or amphetamine in the hair. Most labs are not looking for phentermine in a hair test.
