Hello. : Hello. Ketorolac (toradol) is a nonsteroidal anti-inflammatory drug used for acute pain. Fentanyl is an opioid (narcotic) analgesic for severe pain. Neither of these are barbituates. Do not see how they would trigger a false positive on a urine drug screen.

Drug test: Fentanyl is an opiate. It will not result in a false + result. It will pop positive. Ketorolac isnt an opiate. It will pop negative.
