Hello. I'm Dr. Phil, licensed and practicing Internal Medicine Physician. Excellent service is my goal.
Likely one of your other meds caused the false positive for codeine
Make sure they send the sample for GCMS. This is a chemical fingerprint confirmation test
It will confirm you didn't take codeine

I also take cyclobenzaprine, tramadol, clonidine, amalodipine,, and lisinopril. Could any of these affect the test and could it bfe skewed by a urinary tract infecrtion?
Expert:  Dr. Phil, MD replied 2 years ago.

Yes, the other meds could cause a false positive.

A UTI wouldn't affect it

Make sure you get that GCMS
