Phenergan Drug Test?

Question

I just took some phenergan and I read that it will f up a drug test and test positive for pot. I am getting tested next week. How many days do I need to wait. The phenergan was not prescribed to me but I took it for a tummy ache. If I document that I took it, will I be OK or will they really need a script for it?

I also take Ultram, Lisinopril, Buspar, Metformin all with prescriptions of my own.

What is phenergans half life or detectability timefram?

Btw. I dont use any illegal drugs. I havent smoked weed since 1998 and likely never will again.

Answer 1

Phenergan will not test positive for THC or anything else. Even if a false positive occurs, which it won't, it must be confirmed with a more accurate test to be reported as a positive.
What you should concern yourself with is the Ultram. It is a synthetic opioid and can test positive for opiates. Hold on to your prescription bottles. You may need them.
