A member asked:

If you receive a epidural during labor, will you test positve for barbituates and benzodiazapans ? drug screen was taken after epidural was given!

The : The medications typically used for an epidural while in labor are anesthetics such as bupivicaine, chloroprocaine, and lidocaine. These are not in the barbituate or benzodiazepine families and would not show up on a drug test as such. Sometimes mothers are given a pain killer prior to the epidural which might show up on a drug test as an opioid, but that would have been documented in the medical record. If you have questions about the testing and whether any prescribed medications could have shown up as barbituates or benzodiazepines in the drug screening, you should call your ob/gyne doctor.

Unlikely: For labor epidurals, anesthesiologists typically do not give any benzodiazipines, barbiturates or other sedative drugs as this can affect the fetus. The epidural infusion may contain an opiate (drugs related to morphine such as fentanyl) but these will not create a positive screen for the drugs you listed.

No: Neither class of drug you mentioned is used for an epidural. You might test positive for opiates, but this would be rare because the dose given is so low.

No: Neither is part of a labor epidural.
