If you take hydrocodone can a urine test say it's Darvocet?

Yes, a urine test that screens for opioids may potentially confuse hydrocodone with other substances, but it typically distinguishes between them. Darvocet, which contains propoxyphene, is a different medication and is no longer available in the U.S. due to safety concerns. However, if a test is not specifically designed to differentiate between these substances, there could be a false positive. It's always best to inform the testing facility of any medications you are taking.
