Will the drug lorazepam show up in a urine test and if yes

Customer Question

Will the drug lorazepam show up in a urine test and if 'yes' for how long? In other words, if the 1 mg was taken around 8 p.m. will it show in the urine test taken at 2 p.m. the following day?

Lorazepam can indeed be identified in urine drug tests IF the test includes testing for the benzodiazepine class of drugs. Some drug tests do not include this particular class of drugs, but many expanded panels do include this testing.

If the test is included; the drug would still likely be positive in the urine at that time (less than 24 hours later)

does 1 mg lorazepam fall in the same category as 10-325 percoset???


Expert:  Family Physician replied 6 years ago.
NO - Percocet contains a synthetic opiate (oxycodone) and lorazepam is a benzodiazepine.

what is the difference between an opiate and a benzodiazepine?????
Expert:  Family Physician replied 6 years ago.
They are different classes of medications:

Opiates are "narcotic" pain medications such as morphine, codeine, heroin, Vicodin, Percocet, Oxycontin

Benzodiazepines are sedative/hypnotic medications such as Valium, Ativan, Xanax, Klonopin.
