I was recently hospitalized for a seizure due to an overdose on Ultram. They amount was toxic and?

No is it possible at all that you were around a friend or family member that may have put PCP in your drink? the overdose may have been caused by PCP and not the ultram or it could have been both together.

I agree with the first responder Ultram and PCP and chemically nothing alike, you got PCP in you somehow

Ultram WILL show a false positive for PCP, even at therapeutic dosage.I had a random drug screen and it showed positive for PCP. I had to provide a list of all of my medication and when they found Ultram as a prescribed drug, they dismissed the test as a false positive Do a little research on false positive test results and you will find it. I had that issue arise with me I have never even seen PCP before, wouldn't know what it look like if it was in front of me. I have been in the medical field for 23 years and do not do illegal drugs. My job depends on it and it's not worth the risk anyway. You must consider, amoxicillin can show a false positive for cocaine and they are nothing even closely related .One is a fungus made into an antibiotic medicine and the other come from a plant leaf. Keep in mind, as well, that Afrin nasal spray can show positive for amphetamines. There are a lot of things that can show false positives even if you never figure they will.
