 Typically over prescribed- 30 days instead of 3
 Widely prescribed
 Pharmaceutically pure
 No street drug stigma
 Active orally
 Potent
 Legitimate needs vs abuse potential
Abuse potential of prescription drugs, particularly
opioids, is having significant societal issues!

Hydrocodone- the Most Prescribed Opioid
 Hydrocodone is absorbed and then metabolized to
Hydromorphone
 Hydromorphone is 7 – 10 times more potent than morphine!

Meeting The Prescription Drug Challenge
April 8, 2015
Step
Issue
Comments
1
Policy
Policy always comes first- don’t forget a legal
review!
2
Panel
You can’t find it if you don’t test for it- make sure
your company is using the right panel!
3
Consistency
Use the same panel for all your testing regardless
of reason- avoid collector errors.
4
Require
Disclosure & Train
Supervisors
Require confidential employee disclosure- policy
(non)compliance may be critical. A trained
supervisor can provide evidence for impairment.
5
MRO
Use a board certified MRO- sorting through
legitimate vs illegitimate prescription medication is
better left to a professional.

Step 1- No Testing Without a Policy

Always Hire an Employment Lawyer to Review Your Policy

Step 2- Use the Right Panel.
“Urine 8”- Illegal + Prescription Drugs
.

Test
Drug Class
Cutoff
Make sure cutoff is appropriate
1
Amphetamines
500 ng/mL New more sensitive DOT cutoff
2
Benzodiazepines
200 ng/mL Need lower cutoff & special
screening test for Alprazolam
3
Cocaine
150 ng/mL New more sensitive DOT cutoff
4
Opiates
300 ng/mL Need low cutoff for Hydrocodone
5
Heroin
10 ng/mL New test included in each panelcan be positive by itself!
6
Oxycodone
100 ng/mL Required to reliably detect
Oxycotin, Percodan, Percocet
7
Methadone
300 ng/mL Increasingly common prescription
drug
8
Marijuana
50 ng/mL
DOT cutoff to exclude passive
exposure

Other Drug Step 2 Panel Considerations
Out with the OLD screening tests:
Propoxyphene, MDMA, Barbiturates, Methaqualone, PCP,
Amphetamine 1,000, Cocaine 300,
In with the NEW / relevant screening tests:
Oxycodone, Methadone, Benzodiazepines, Heroin,
Amphetamine 500, Cocaine 150,
Out with the OLD confirmation tests:
“DOT Opiates”: Morphine and Codeine only
In with the NEW / relevant “Expanded Opiates” confirmation
tests (will be in DOT panel in 2 years):
Morphine and Codeine 2000
Hydrocodone / Hydromorphone 150
Oxycodone / Oxymorphone 100

Consistency & Disclosure
Step 3: Consistency helps reduce errors. If you have only one panel
you will avoid “the wrong panel” syndrome. Keep it simple.
Step 4: Important issues if you have a post accident or reasonable
suspicion drug screen.
If a prescription drug is detected and it was legally prescribed- policy
becomes paramount.
The MRO will NOT be able to determine impairment using urine
drug levels.
If the employee failed to disclose a detected prescription drug- you
will have a policy violation.
If a trained supervisor documented objective evidence of
impairment- you have a policy violation.

Step 5: A Board Certified MRO
Board certified MROs can
•investigate prescriptions without violating HIPAA laws.
•Interview donors regarding their medical conditions.
•Review chain of custody documents.
•Legally provide a safety concern if an employee has a detectable
prescription drug that could cause on the job impairment and result in
increased accident risk
SAFETY CONCERN: A legally prescribed Hydrocodone is detected
in Joe’s urine in a pre-employment drug test for a fork lift operator.
Reported Negative after an interview- no safety concern: A legally
prescribed Alprazolam metabolite is detected in Suzy’s preemployment drug test for a receptionist.
